Intermittent Fasting

When you’re on a quest to be the fittest, healthiest version of you, working out is only part of the equation. If you’re training hard, you need to optimise your recovery and make sure that you are fuelling your body properly – this means getting clued up on nutrition.

As with so many things in health and fitness, there are a wide variety of different approaches – it’s a case of experimenting with what works best for you, your lifestyle and your body. One concept that has recently grown rapidly in popularity is “intermittent fasting” (IF). This involves cycles of fasting and eating which can be adapted depending on your age, activity level and lifestyle.

So first, let’s take a look at the benefits of fasting…

Weight loss

Intermittent fasting is often used as a tool for weight loss, and with good reason. Following a conventional eating pattern, we fast between dinner and breakfast – hence the name for our first meal of the day, where we “break” our “fast”. Lengthening the time you spend fasting and restricting your “feeding window” automatically makes it easier to reduce your caloric intake, which is one the key things to focus on when it comes to driving weight loss (the other, of course, being increased physical activity).

However, this will only work as long as you don’t overcompensate for your fast by eating excessively during your allocated eating hours! If your calories are the same as what you would usually eat, or if you find yourself unable to resist overeating calorie-dense foods when you are “allowed” to eat, then maybe intermittent fasting isn’t the best approach for you, especially if weight loss is your goal.

Inflammation reduction

Inflammatory responses in the body are a vital part of the immune system, helping to heal injuries, defend against viruses and bacteria and repair damaged tissue. However, it also has the potential to do a great deal of harm when the body mistakenly starts to attack its own tissues. Low-level, chronic inflammation has been linked to a long list of chronic health issues, from heart disease, autoimmune conditions, arthritis, diabetes, cancer, digestive problems, anxiety, depression, brain fog, and hormonal problems.

A number of studies have suggested that fasting can reduce inflammation, by triggering anti-inflammatory responses such as:

  • Positive changes in the composition of gut microbiota
  • Reduction of insulin resistance
  • Increased immune response in cells
  • Increased production of β-hydroxybutrate, a compound that blocks part of the immune system responsible for inflammatory disorders like diabetes, Alzheimer’s disease or rheumatoid arthritis
  • Significant reduction in the presence of inflammatory markers such as cytokines, C-reactive protein

Enhance your gut health

When we refer to  the “gut”, we mean the digestive tract that your food passes through, which encompasses many different parts of the body, including the oesophagus, stomach, small and large intestines and the colon. Within the gut, an army of microbes (vast numbers of microorganisms and diverse bacterial communities) work with our cells to keep us alive and healthy. Around 80% of our immune system lives within the gut microbiome, impacting almost every aspect of how we feel. As well as supporting our immune system, good bacteria in the gut can soothe inflammation, promote absorption of nutrients and minerals, stabilise glucose levels, balance hormones, aid digestion and fight against bad bacteria and pathogens that contribute to disease. There is even evidence that the bacteria in our gut plays a key role in our mental and emotional wellbeing.

Constantly eating, going from breakfast to snack to lunch to snack to dinner, means that not only are we out of touch with our body’s hunger signals, we are also constantly digesting food. We have something in our stomachs all the time. Humans are the only animal with constant access to food – and this is a relatively recent change in our dietary habits. Our ancestors had to forage for their own food (no 24-hour supermarkets back in caveman days!), so they did not follow a clockwork regime of 3 meals per day with a steady supply of snacks to graze on in between. Evolutionarily-speaking, our bodies are actually designed to cope for fairly prolonged periods without food.

Fasting gives your overworked gut a break from constantly processing our food and allows it to devote time to the many other roles it has to play. What’s more, when you fast, your blood sugar levels and insulin concentrations both fall, which may help to reduce the risk of developing Type 2 diabetes by reducing resistance to insulin.

Boost brain health

Intermittent fasting causes an increase in levels of a brain hormone called BDNF, which promotes the growth of new nerve cells and increases the resistance of neurons in the brain to dysfunction and degeneration. Some studies have shown that changes in neurobiological mechanisms triggered by intermittent fasting can help to prevent the onset of conditions like Alzheimer’s.

Ongoing research shows that adjusting meal size and frequency may affect human health more deeply than we realised, so in the future IF may well be used as an approach for disease prevention and treatment.

Learn to recognise your body’s hunger signals

If you think about it, we very rarely experience “real” hunger. We eat breakfast because our parents drilled into us that it’s “the most important meal of the day”, we automatically reach for our lunch when it hits 12.30 because this has always been the designated lunch break granted to us by our teachers, and, later, our bosses. Eating on autopilot, we rarely stop to ask ourselves whether or not we are actually hungry. Extending your fast is a way of learning what hunger actually feels like, so that you are better able to distinguish between eating out of habit and eating in response to your body actually sending you signals that it needs fuel.

Becoming more in tune with your body is really empowering and especially important when you’re trying to learn what works best for you as part of a commitment to improving your health and fitness.

Different types of intermittent fasting

There are many different types of intermittent fasting – as touched on earlier, it’s all about finding the approach that works best for your lifestyle and your body. It can be worth experimenting with different approaches and seeing how you feel.

Firstly, we have the 16:8 method. In this kind of IF, you limit yourself to an 8-hour feeding window, fasting for the other 16 hours of the day. The easiest and most popular way that people achieve this is to skip breakfast, then eat from 12PM – 8PM. This is ideal if you work out in the afternoon, as you can eat some healthy carbohydrates for lunch, with plenty of calories left for a post-workout protein shake in the afternoon before dinner. It’s relatively easy to stick to, as you only need to skip one meal, so it’s a good place to start if you’re new to fasting

A second approach is the 24-hour fast. This one is fairly self-explanatory and involves fasting for an entire day at a time. People following this method usually do one to two fasts per week, by not eating from one dinner until the next. This is more challenging than the 16:8 approach and will likely be pretty difficult to adhere to if you’re new to fasting.

The 5:2 method is a third approach and in terms of difficulty sits somewhere between the 16:8 and 24-hour methods. Popularised by celebrities in recent years, this type of fasting requires you to eat normally 5 days of the week, then restrict your intake to 500-600 calories for 2 non-consecutive days.

With all these approaches, the key is to eat normally when not fasting. If you overcompensate for the fast by eating a ton more calories than you normally would, then a calorie deficit is not achieved, which is usually one of the key objectives achieved by trying out IF.

Working out and intermittent fasting

It goes without saying that if you choose to experiment with intermittent fasting, you need to do so sensibly and figure out when it makes sense for you to eat! You need to have enough fuel to work out, and you should be able to nourish your body with carbohydrates and protein after an intense session at the gym. So, opting to fast from dinner to lunch the next day if you’re planning a workout at 9am may not be the best strategy – not only will you be running on empty, you also won’t be able to refuel immediately. Not ideal.

Top tips

  • Don’t overeat when in your feeding window – this defeats the point if your goal is weight loss
  • You can’t intermittent fast yourself out of a bad diet – you still need to focus on building a healthy diet, that includes plenty of veggies, fruit, good sources of protein and wholesome carbs
  • Make sure that you stay hydrated during your fast. As well as water, you can have herbal tea and coffee without milk or sweetener during your fasting hours
  • Many people successfully use intermittent fasting as a tool for weight loss, as it helps them to reduce the number of calories they consume. However, as with any diet that puts you in a calorie deficit, it’s key to ensure that your protein intake is adequate and that you perform regular resistance training. This will help to ensure that the weight you lose comes from fat, not muscle, and therefore improve body composition
  • Ease into it – it won’t be easy at first to go without food when you’re used to eating! Set yourself achievable, realistic goals. Try extending your fast by an hour at a time, taking a couple of days to adjust before extending again when you feel ready to

5 Top Tips For Choosing Your Protein Bar

Not all Protein Bars are made the same. Here are our Top 5 Tips for choosing the right Protein Bar for you.

After the effort, the reward. You’ve just finished a tough session with your trainer, now it’s time to refuel. If you’re after something quick and convenient – maybe you’re in a rush or want something desk-friendly – then a protein bar seems like the logical choice. But with so many options to choose from, what do you go for?

Dodgy marketing tactics – i.e. slapping a healthy label on sugar-laden bars – is incredibly frustrating when we’re trying to make the right choices. So, we’ve put together a quick guide to decode protein bars and make your life a little easier.

Rule #1 – At least 10g of protein

Protein plays a number of really important role in our bodies and is a building block for our tissues and organs. Getting in some post-workout protein is really important when it comes to helping your muscles recover and grow, so if you’re opting for a bar, you need to make sure it offers a decent helping of protein.

Be wary of bars with protein concentrates or soy “crisps” – these aren’t always the best option as they won’t be utilised as readily by the body as more complete sources of protein. Bars that contain pea protein are often a good bet!

Rule #2 – Less than 15g of sugar

It’s easy to be tricked into thinking something is healthy, when actually it’s packed with hidden sugar. Shockingly, one report (published by Food Navigator USA) found that over a third of nutrition bars contain more saturated fat than a glazed donut from Krispy Kreme. Whaaaaattt! And, as if that wasn’t bad enough, ten of these “healthy” bars actually had more sugar than the doughnuts.

So, have a quick scan of the ingredients. Is one of the main ones sugar or glucose syrup? Avoid! Any sugar in a bar should come in small amounts and be from natural sugars, like brown rice syrup, maple syrup or dates.

Rule #3 – Around 150-250 calories

Protein bars are a convenient way of getting in a little dose of protein post-workout, or fuelling you with some energy to get through the day, but they shouldn’t be used as a meal replacement, as you’re unlikely to meet all your nutritional needs this way. A bar that contains between 150-250 calories can easily be worked into your daily calorie needs.

Rule #4 – At least 3g of fibre

Choosing a bar with a decent serving of fibre will help to keep you feeling fuller for longer and promotes good gut health. Most adults in the UK don’t get enough fibre, so this is something to bear in mind not just when you’re buying a quick snack after the gym, but when you’re doing your weekly food shop!

Rule #5 – Avoid overly processed, artificial bars

A bar might look healthy on the shelf, but if you flip it over to see a loooong list of unpronounceable gibberish where you should be seeing ingredients… It may not be the best thing for you and your body. This is a common sense rule that can be applied whenever you’re shopping for food – try to opt for food with proper ingredients that will fuel your body in the best possible way.

The Importance Of Rest Days

Getting in your workouts and nailing your nutrition is crucial when it comes to achieving your fitness goals – we all know that. Chances are you take the time each week to schedule in your training sessions and think about what your meals are going to look like. But are you also planning your rest and recovery?

Adequate recovery time is hugely important, but it’s all-too-often overlooked. And this is true of everyone – fitness junkies sometimes dismiss rest as unnecessary and boast that they train hard every day, while on the other end of the scale, fitness newbies may feel they have some catching up to do and end up setting themselves ambitious aims to train hard five, six, seven times per week to maximise their progress.

But in reality, everyone – whether they’re new to fitness or have been training for a while – needs to give their body enough time to rest and recover. It might be tempting to go all-out, but rest is a crucial part of your training. If you’re wondering why, keep reading.

You’ll notice we’ve added links to other Fitness Lab blogs throughout this article. We’ve added these blogs so you can get more in-depth information on any subject we’ve covered here. You can start exploring these detailed blogs here: Why Are Gym Rest Days Needed?

Allow muscle recovery and growth

Anyone who has challenged themselves in the gym will be familiar with DOMS – muscle soreness and stiffness that lasts for a couple of days after a tough workout. This pain because exercise creates microscopic tears in our muscle tissue that occur when we work out. It’s a completely normal part of the muscle growth process – it is when these muscle tears knit together and repair that the growth and strengthening occurs.

These small tears naturally start to repair when we stop overworking them. The muscle fibres compensate for the damage by physically re-building themselves to be bigger and stronger, so that they can cope better with the stress from an exercise routine in future. Refusing our body the chance to recover therefore means compromising our muscle’s ability to grow.

This is where workout splits can come into play if you’re lifting heavy on a regular basis. Put simply, this means staggering your workouts in such a way that allows you to vary the muscle group you’re working, so that each one has a chance to rest before being exerted again. When you train with us at Fitness Labs, one of the first things your coaches will do with you is to sit down and chat about your goals and your current schedule. They will put together a personalised workout plan that optimises your ability to reach your goals and will factor in adequate rest time, to make sure that you don’t overtrain.

If you’d like to learn more what your muscles do when you take a rest day, you can get more indepth information in our dedicated blog: Are Rest Days Good for Muscle Growth?

Reduce your risk of injury

A really common consequence of overtraining is injuries. If your body is refused the chance to repair after intense workouts, it could lead to weaknesses and injuries that prevent you from training properly. Overuse injuries can be avoided by giving your joints and muscles the time to rest in between workouts. The rest time you need will vary depending on the type of training you’re doing and how experienced you are when it comes to fitness – don’t worry, your coach will be there to guide you through this!

Immune system health

Regular exercise has been shown to boost immune health (for example, studies have shown that people who exercise regularly have a higher number of the bacteria-attacking cells called macrophages). However, intense exercise does put your body under a certain degree of stress, so it’s important not to overdo it. When it comes to your immune system, there are a number of ways over-exercising can impact you. Notably, our bodies’ stress hormones (cortisol and adrenaline) raise blood pressure and suppress the immune system. This has been linked to a higher risk of infection in endurance athletes after extreme exercise (e.g. triathlons).

Ensure you enjoy your workouts and prevent burnout

There are lots of physical advantages to prioritising rest and recovery, but it’s equally important to consider your emotional and mental wellbeing, too. Mental fatigue can be just as draining as physical fatigue, and taking a rest day can help to rekindle your desire to train, making sure that your training stays FUN.

You should never feel as though you’re having to drag yourself to the gym – if that is the case, then it’s a sign that you’re tired and need a day to reset. Enjoy a rest day or two, then come back strong and find the fun in your workouts.

Create sustainable fitness habits

Arguably the most important factor when it comes to achieving your goals is consistency, with both your nutrition and your workouts. So, you need a level that you can sustain – you might manage a couple of days of hitting the gym at max effort, but pretty soon you’re going to burn out. Balance out higher intensity workouts with steadier sessions, stretching and complete rest days.

If your workout regime isn’t sustainable, you won’t stick to it, which means you won’t see results. This can lead to a vicious cycle of bursts of intense training, burning out, loss of motivation and periods of not doing anything, before again picking up an intensive new regime that you will ultimately abandon. Stick to a steady-paced programme that you can maintain, trust the process and the results will come in time.

Can rest days help with weight loss?

If you’re focused on losing body fat, it can be tempting to just forget about rest days and concentrate on burning calories at all costs.

The trouble is, ditching your rest days does come at a cost. A lot of the time, this cost impacts your body’s ability to burn the fat that you’re keen to get rid of.

If you approach exercise with a ‘no rest days’ mentality, you’ll likely end up increasing the amount of stress hormones in your system. Stress hormones – in particular ‘cortisol’ – can do all manner of damaging things to your ability to burn fat. If you’re experiencing poor sleep, an increased tendency to snack, and a lack of focus, it’s possible that cortisol is at least partly to blame.

Personal Training London

As we’ve already covered, it’s important to incorporate rest days to make sure you’re building muscle effectively. Even if you’re not weight training, adding muscle to your body is the single most effective thing you can do in the gym if you want to burn fat.

This is because muscle requires energy just for maintenance. The more muscle you have, the more calories you burn at rest. Therefore, anything you can do to encourage growth of your muscles makes you an even better calorie-burning machine. What’s better than burning calories while you rest?!

For a more in-depth look at losing weight and rest days, take a look at our blog: Why Are Rest Days Important For Weight Loss?

How many rest days per week should I take?

It really depends on how long you’ve been training and what type of training you do. There is no one-size-fits-all. You might be able to tell that you need a rest day before you next workout because you feel too tired to get through what you normally can. Maybe you feel like you’re having to drag yourself to the gym, whereas you’d normally leap at the chance to do a workout.

The best advice – as with so many things related to health and fitness – is to take the time to get to know your body and listen to what it tells you. Understanding what too much exercise feels like and how much rest you need is an important part of staying healthy.

What to do on a rest day?

Taking a rest day doesn’t necessarily mean spending a day glued to your sofa, binge-watching Friends and eating aaaaaall the snacks (as good as that might sound).

Instead, it’s worth understanding what an ‘active rest day’ is. This is a kind of active recovery that might mean going to a relaxing yoga class, or still going to the gym but avoiding high-intensity or heavy workouts. You could warm up and go through mobility drills or stretches, or skip the gym entirely and go for a walk, gentle swim or cycle. Low impact exercise still counts as rest (“active rest”) and, crucially, getting enough rest can be good not just for the body for the mind, too.

We’ve explored some rest days ideas in our dedicated blog: What Should I do on Gym Rest Days?

What should I eat on rest days?

There’s no blanket rule around what you should eat on rest days. Ultimately, the answer depends on what your health goals are. Beware of any source of information that says you should always cut your calories on rest days – this simply is not true for most people.

If your only goal is fat loss, there may be some merit in reducing calories while you let your body recover.

However, if you’re looking to build muscle at the same time as reducing fat (one of the most effective ways to do so), then reducing calories on rest days can counteract your goals somewhat.

Of course, there are lots of people who train with the goal of bulking up. For people with this goal, you may even want to look at increasing calories on rest days.

So, as you can see, there’s no one-size-fits-all answer. Recovery days – like your workout routine – should be tailored to you. If you’re interested in getting a more in-depth look at what rest days might look like for different people with different goals, take a look at our blog: What Should I Eat on Rest Days?

Strength And Getting Older

It is estimated that people lose around 3-5% of their muscle mass per decade after they reach 30, with this rate of decline higher in inactive individuals and accelerating in all of us after the age of 60. This loss of muscle mass and strength is a serious cause for concern, as it contributes to the overall increased frailty and reduced mobility that can strike in advanced years, both of which lead to a higher risk of falls and injuries.

Why do we lose muscle in old age?

There are a number of factors that contribute to age-related muscle loss, a phenomenon which is also referred to as sarcopenia. As we grow older, our muscles become resistant to normal growth signals (nutrition and exercise), in a process known as anabolic resistance. When studying the muscles of older individuals, we do not see the normal increases in muscle protein synthesis (the repair and growth of muscle tissues) after exercise. Although this phenomenon is more common in older populations, it is becoming increasingly common in younger people, a fact that is likely caused by our steady decline in physical activity and increasing rates of chronic inflammation (which is itself a major contributory factor to muscle loss).

Other causes of muscle loss as we age include hormonal changes, specifically of those hormones that have a role to play in muscle mass maintenance, including testosterone and oestrogen.

The menopause and muscle loss

While age-related muscle loss impacts both men and women, women are particularly vulnerable. Studies have shown that after the menopause, the loss of muscle force relative to muscle mass accelerates at a much faster pace than in men of the same age.

This is primarily due to a steep decline in the release of ovarian hormones, with the decrease in oestrogen playing a key role in the loss of both muscle and bone mass. A decrease in muscle mass exacerbates postural issues and contributes to the deterioration of bone health, both factors which increase the risk of osteoporosis (a medical condition in which the bones become brittle, fragile and prone to fractures).

The oestrogen deficiency that occurs around menopause coincides with other lifestyle changes that often appear as we approach our later years. Most notably, levels of physical activity tend to drop, causing us to become more sedentary. As fitness becomes less of a priority, poor nutrition habits may also start to creep in. Combined with the poor sleep quality and high stress levels that many of us are facing across all age groups, we have a “perfect storm” for not only muscle loss, but also fat gain. The result is the loss of muscle tone and weight gain around the middle that we often see in middle age and beyond.

Countless studies have shown that across all age groups, women are consistently less physically active than men and participate much less in resistance training, which will accelerate their already higher rate of muscle loss and place them at an even higher risk of losing muscle mass, experiencing weight gain in middle age and ultimately suffering from increased frailty due to poorer bone health in their advanced years.

Can we prevent losing muscle as we get older?

Losing muscle is generally accepted as an unfortunate, but normal, part of the aging process, however that does absolutely not mean that we are powerless to stop it. While some of the factors that contribute to age-related muscle loss are largely beyond our control (hormonal and neural changes), all the evidence agrees that it is massively compounded by inactivity and poor nutrition. Meaning that there is a great deal that we can do to maintain our muscle as we get older. Studies have also demonstrated that we can continue to build muscle well into our eighties (!) so it is absolutely never too late to start.

The importance of resistance training 

Working with weights in the gym is hugely beneficial across all stages of life, but it should remain a key part of our exercise regimes in later years. As our muscles become less responsive to normal growth stimuli, regular resistance training can help to counteract this and encourage our body to maintain muscle mass. Resistance training not only serves to build muscle, but also to burn fat, meaning that we can help to optimise our body composition well into our retirement.

When it comes to maintaining bone health, weight training again has a huge role to play, with a higher rate of bone formation associated with mechanical loading. Frost’s mechanostat theory was the first to propose that bones will grow stronger in response to stress, and stated that “the bone possesses an inherent biological system to elicit bone formation in response to high mechanical strains, thereby strengthening the bone”. His theory, which has been supported by a large number of studies, suggests that bone formation is site-specific, in other words it is increased in areas of high strain.

This kind of research is highly relevant when we consider the menopause and high prevalence of fractures caused by osteoporosis. One particular study looked at postmenopausal women and concluded that resistance training successfully reduced bone loss in the hip and spine. Hip fractures are one of the most debilitating and life-changing injuries in later life, as they almost always have a severely detrimental impact on independence and quality of life. Weight-bearing exercises that elicit physical loading to the lower limbs can therefore promote bone strength in the hip region

Key takeaways

The decline of skeletal muscle with age is one of the key causes of functional decline and loss of independence in older populations. Women are particularly vulnerable to the effects of this, primarily due to the steep decline in oestrogen that occurs around the time of the menopause, triggering deterioration of both bone strength and muscle mass.

Resistance training benefits us at all stages of life, but it should remain a key part of exercise regime in later years. As well as maintaining muscle mass and strength and promoting strong and healthy bones, resistance training has a positive effect on body composition, hormonal and stress regulation, sleep and cognitive function.

The Importance Of Sleep

When looking to optimise their health, the first things most people consider is getting some workouts in and sorting out their diet. Whilst these two things are obviously critical, often overlooked is the importance of getting enough sleep.

We all know that getting seven or eight hours of shut-eye is ideal, but unfortunately, when we’re busy, good sleep habits tend to fall by the wayside. This can be a problem when trying to fit in your weekly workouts, especially if you’re already juggling work commitments and a social life.

Sacrificing an hour of sleep may not seem like a big deal, but when you’re trying to make progress in the gym, a lack of rest can really derail your progress. Sleep has a profound impact on all aspects of our health, not just physical (e.g. digestion, immune system, hormonal balance…) but also psychological (stress and depression can be triggered or worsened by sleep deprivation).

When considering its impact on our health and fitness, there are a vast number of benefits that adequate sleep has to offer, as summarised below:

Prevent illness

Sleep has a profound effect on our immune system, with research showing that people who get fewer than five hours are 4.5 times more likely to get a cold than those who sleep for 7 hours. In the long-run, taking an extra rest day here and there to make sure you’re getting enough sleep could prove less disruptive to your training (and general life) than working too hard and making yourself ill.

Drive your performance

When you do resistance training, you are actually causing tiny tears in your muscle fibres. Your body then repairs these micro-tears and over time the muscles adapt to better handle the demands that caused the initial damage. This is how muscles grow (the process is referred to as hypertrophy). This recovery process happens while we sleep, so ensuring that you have a good sleeping pattern will really help your training – indeed, sleep is sometimes referred to as “nature’s sport supplement”.

Also, although it may seem obvious, it’s worth pointing out that by getting enough sleep, you have the energy needed to power through tough sessions at the gym. You can’t expect to push past PBs if you’re struggling to stay awake and yawning your way through sets. Arrive at the gym fully rested and alert, ready to give it your all and you’ll be far more likely to smash out a great session.

Achieve your weight loss goals

Years of research has proven that there is a solid connection between weight and sleep. Hormonal changes in your body take place as a result of the amount and quality of your sleep. Crucially, the hormones ghrelin and leptin, which increase appetite and signal satiety, respectively, can fluctuate with insufficient sleep. This can mean feeling hungrier and struggling to feel satisfied when you eat. So, a lack of sleep can not only leave you lacking energy for your workouts, but can also make you feel hungrier. This combination means that you may be burning fewer calories, but consuming more – the opposite of what you want if you’re aiming for weight loss…

Research by Harvard University has confirmed a strong link between insufficient sleep and weight gain. There is a possibility that insufficient sleep impairs brain reward systems, including those that govern energy intake, judgment, and food choice. Some studies suggest that sleep-deprived people eat fewer vegetables and gravitate more toward sweet, fatty foods.

Furthermore, a lack of sleep can have a detrimental impact on your metabolism, as rest helps to regulate our metabolic rate.

Boost heart health

A lack of sleep can put your heart at risk – studies have shown that “short sleepers” getting fewer than the recommended 7 to 8 hours of sleep per night have a significantly higher risk of developing and ultimately dying from coronary heart disease – plus they also have an increased risk of suffering a stroke.

So, it’s obvious by now that sleep is something you should be prioritising as part of a healthy lifestyle. If you struggle to sleep, check out our top tips below:

  • Keep your room cool and dark
  • Have a consistent bedtime routine, so that your body knows when it’s time to start winding down. Having set rituals, like a cup of tea or half an hour of reading before bed, can help you to relax
  • Limit your use of technology before going to bed – the blue light in your phone can prevent your brain from “switching off”. Scrolling through Instagram can wait til the morning!
  • Exercise! There are a number of reasons why it can help you to drop off – an obvious one being that you need to recuperate after expending lots of energy. Also, as your body temperature rises during exercise, the drop in body temperature that comes after you’ve cooled down can trigger the signals your body needs to help fall asleep. So, a walk after dinner, for example, could be really beneficial if you’re someone that struggles to fall asleep.

Why You Should Track Your Calories

If you’re going somewhere new, do you HAVE to use a map? No – but it helps. The same applies with calorie tracking. You can probably get to where you want to be without it, but it is undoubtedly the best and most efficient way of getting you there.

Before we delve into why you should track your calories, let’s begin with a quick definition of what we actually mean by the term “calorie”. In a nutrition setting, it’s an abbreviation for kilocalories, the amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree Celsius. When referring to food, it measures the amount of energy contained in the food and drink we consume. Everything we do relies on the energy that we consume in the form of calories. Ever heard of the saying, “food is fuel”? It is exactly that.

If we eat exactly the amount of calories we need to fuel our body’s metabolism, digestion and movement throughout the day, then we will maintain our weight. Once our body’s immediate energy needs are met, any excess is stored for future use – some as glycogen in our muscles, but some as body fat. Conversely, if we consume too few calories, then our body will lose weight as it turns to other sources of energy, including fat. However, to know what is “too much” or “too little” requires us to actually monitor our intake.

Disclaimer – if you have a history of disordered eating and the prospect of tracking your calories is something you know is a trigger for unhealthy behaviour and anxiety, calorie tracking may not be for you right now. At the very least, please make sure that your coach is aware and can support you in the process. 

Calorie tracking is most commonly associated with weight loss, however it can help with a wide variety of goals, including weight gain and body recomposition. In this blog, we will be focusing mainly on calorie tracking from a weight loss perspective – a process that people tend to overcomplicate. There is a mind-boggling number of different diets, each with its own tribe of loyal supporters fiercely proclaiming it to be the best way to lose weight. Keto, paleo, 5:2, IF, raw, high carb, low carb… However, if you look closely at the food diaries of people who have successfully lost weight by adhering to these diets, you’ll see that despite being vastly different, they have one crucial thing in common: they help the dieter to achieve a calorie deficit.

Which brings us to reason number 1 to track your calorie intake…

  1. To understand what your current intake is and give you a baseline to work from

Understanding where you’re at is key to getting where you want to be. As a general rule, most of us tend to underestimate the amount of calories we consume and overestimate the amount of activity that we do. Without a baseline, you have no idea what target to set yourself.

For example. You plug in your height, weight, activity level and so on into a calorie-tracking app. It suggests that you should aim for 1,500 calories per day. Sounds reasonable. However, if you have inadvertently been consuming in excess of 2,500 calories every day, then this diet will feel very restrictive and hard to stick to from the beginning. Instead, work out your current daily average, then start slow with a deficit that is more easily manageable. Once you have adjusted, you can bring your calorie intake down again. It’s all about steady, sustainable progress.

  1. To understand what eating behaviours you have that you need to modify in order to lose weight 

Tracking your calories can highlight some habits that you might not realise are hindering your progress. Grabbing a coffee in the morning, for example – you might not think this would have a big impact on your calorie intake for the day. However, depending on what you go for, this could actually make a huge difference. Some lattes pack upwards of 350 calories per serving, whereas an Americano has just 15 calories.

You may unconsciously reach for biscuits at work, thinking “Ah, one or two won’t hurt”. Two chocolate digestives, however, can add 200 calories to your day – without offering you many nutrients in return. And sometimes, the healthy options can be deceptively high in calories. Having a salad for dinner may seem like a great choice, for example, but if you’re liberally drizzling olive oil all over it, you may unwittingly be eating far more calories than you intend to. Just one tablespoon contains about 120 calories, but it’s easy to accidentally double this if you’re not using a measuring spoon. Similarly, nuts are often touted as a great healthy snack (and they are!) but be wary that they are high in fat, and not sticking to the prescribed portion sizes can cost you hundreds of calories.

“Eyeballing” your calories can often lead to you unwittingly adding on 200-300 unnoticed calories throughout the day, especially when it comes to calorie dense foods like peanut butter, oils and nuts.

For sustainable weight loss, we’re looking to create a moderate deficit of no more than 20% of your daily intake, often considerably less than this – so you can see how adopting just small changes like swapping the coffee you have in the morning and opting for a healthier snack option in the office can make a huge difference.

  1. To understand your daily versus weekly calorie balance

It is very, very common for people to stick to a calorie deficit during the week and then land themselves in a surplus at the weekend – the net result being that across the week, they average out at maintenance and therefore do not see any progress.

Why does this happen? Well, there may be a wide range of causes, but there are two situations that we see quite a lot as trainers.

Scenario 1 – moderate weekly calorie deficit undone by mild overindulgence at the weekend

Throughout the week, you adhere to a fairly moderate deficit of 200 calories per day. Despite being a small deficit, this would still generate weight loss if committed to for the whole week, seven days. However, at the weekend, the deficit of 1,000 calories (200 daily for 5 days) is almost immediately undone with a few untracked treats that tip the balance of the scale back to “maintenance” when you average out calories across the week.

A few drinks and handfuls of bar snacks may be enough to land you in maintenance or an overall surplus. And actually, it is incredibly easy to accidentally land yourself in a massive calorie surplus when you go out for dinner and don’t track your meal. Many high street restaurant chains have main meals on their menu that add up to 800, 900 even in excess of 1,000 calories. This isn’t always obvious, as portions might not look unreasonably huge, but the sauces and oils are rich and can really stack up the calories. And that’s before you take into account the bread you eat before your meal, the wine you drink alongside it, or the dessert you may decide to treat yourself too (another easy 600 calories).

A great illustration of this is shown in the below infographic from @cartergood

Scenario 2 – extremely restrictive calories in the week leads to binge-eating at the weekend

You plug in your height, weight and activity level into your calorie tracker. Next it asks you what your desired speed of weight loss is. Well, duh… ASAP, right? That’s what you click and, ouch – it gives you a startlingly low figure of 1,200 calories. Never mind, it is Monday and you are 100% motivated and committed to your weight loss target so you resolve to stick to it.

Monday to Friday crawl by and you’ve managed to stick to your stingy calorie target. Same breakfast, lunch and dinner, no thank you to the office cookies and you skipped work drinks on Friday. The problem is, you are now craving all your favourite foods that you have told yourself are “forbidden”. And now that it’s the weekend… An “all-or-nothing” mentality is triggered, causing you to binge out and savour your treats “while you can” in anticipation of another miserable, restrictive week ahead. Not only is the calorie deficit wiped out, you’re also cementing yourself in a vicious restrict-binge cycle that is detrimental to not only your physical health but also your mental well-being.

The bingeing at the weekend is not the real problem. This overeating at the weekend is a response to drastic undereating for the previous five days. So, the restrictive food habits taking place during the week that need addressing as a priority – this will then prevent you from overeating at the weekend. A good trainer will help you to put together a sustainable food plan that keeps you in a moderate, manageable calorie deficit, while still allowing you the flexibility and freedom to include your favourite treats, in reasonable amounts. Calorie-tracking will be key to achieving this.

Eating more during the week will leave you feeling more energised, which will have a direct impact on the quality of your training, your stress levels and your relationship with food. It will also prevent overeating at the weekend, helping you to create a more balanced calorie intake throughout the week – staying in a calorie deficit without depriving yourself and feeling unbearably hungry.

  1. To help monitor your behaviour and keep you accountable

So, you’ve looked at your current intake and addressed where you need to improve. The next step is simply to implement the changes, for the long-term. Tracking your calories and sending the screenshots to your trainer is a fantastic way to help you stay on top of your plan. You’re less likely to reach for an extra cookie if you’re committed to tracking your calories and know that this will tip you over and impact your progress for the week. And you’re less likely still to give in to temptation if you’re sharing every bite with your trainer!

Key takeaways: our top tips for tracking your calorie intake

  • Understand where you are before making any drastic changes to your diet
  • Set a realistic calorie target – nothing too restrictive. If you’re looking to lose 5kg or more, then you’re in this for at least 6-10 weeks. So it has to be sustainable! Prioritise realistic changes that you can maintain for life
  • Create your calorie deficit by reducing your intake of the least filling and least nutritious foods (alcohol, sweet treats, fancy coffees, etc)
  • Make room for your favourite foods instead of banning certain things from your diet. It’s all about moderation

Vegan Protein Sources

For a variety of reasons, more and more people are adopting a plant-based diet. Arguably the most popular question (apart from, “But don’t you miss cheese?!”) that vegans get asked is, “Where do you get your protein from?”.

In this blog, we will answer that question, sharing top plant-based sources of protein, as well as some tips for incorporating them into your diet.

Sidenote! If you’re looking for some fantastic healthy vegan places to eat that are close to Fitness Lab, who not check out our list of The Best Places For Healthy Eating in Soho (and Nearby!)

Complete vs. incomplete protein

Before we delve into it, first a quick word on the two different types of protein. Animal protein is often referred to as being a “complete” protein, because it contains all nine essential amino acids that our body needs. Plant-based proteins, conversely, are labelled “incomplete”, as they rarely contain all of these protein building blocks. This can lead to the misconception that vegan protein is in some way inferior, or that a vegan diet is by default lacking in nutrients, but this is definitely not the case!

You can very easily get all the amino acids you need from a vegan diet by simply eating a variety of plant-based proteins. For example, including legumes and wholegrains into your daily diet will ensure that your body has all the amino acids it needs. What’s more, you don’t need to combine these incomplete proteins together in one meal – as long as you incorporate these different proteins throughout the day, you will get everything you need.

So – where do you get protein on a vegan diet?

Plants

Yep, veggies contain protein! This is commonly overlooked, but important to understand. People often equate protein with meat, and can be surprised to learn that plants have protein in them, too. 100g of spinach contains about 7 grams of protein, for example. 1 cup of green peas offers about 9 grams. Other veggies to include for a little extra protein include broccoli, kale and corn. Even the humble potato offers a little bit of protein.

Grains

Quinoa is one of the best grains you can opt for in terms of protein, providing 14 grams per cup as well as all nine essential amino acids that our body needs. Wild or brown rice provides about 7 grams of protein per cup. Bulgur, barley, aramanth, buckwheat, kamut and millet are also great ones to try that offer around the same amount.

Beans and pulses

Beans and pulses are a cheap way of adding lots of protein to your diet, alongside fibre (which most of us are severely lacking in) and a whole host of other nutrients. Lentils are a particularly great source of protein, offering 26g of protein per 100g. They’re super versatile – try making lentil dhals, mashing them to form the base for veggie burgers or using them to thicken soups and sauces.

Some other great high protein options include chickpeas, edamame, black beans, kidney beans and butter beans. Tip: these are considered an incomplete protein. But, by combining any of these with a grain like brown or wild rice, you’ll get all nine essential amino acids in one meal.

Nuts and seeds

Although they are also high in fat, nuts and seeds (and the spreads made from them) pack a great protein punch too. Peanuts, for example, are one quarter protein. Try adding a tablespoon of peanut butter to a smoothie – this is a great way to incorporate some healthy fats as well as protein. Similarly, almonds are made up of over a fifth protein – try adding flaked almonds to salad or a spoonful of almond butter with some apple slices.

Adding seeds to salads is a good way to up your protein intake – sunflower seeds, for example, have 21g of protein per 100g. However, like nuts, they are also high in fat, too, so eat them in moderation.

Non-dairy milk

One cup of soy or almond milk can pack about 9 grams of protein, as well as a whole range of other nutrients. There are a ton of different plant-based milks out there to try – soy, almond, coconut, oat, hazelnut, rice, hemp… Different brands and varieties have different nutritional properties and flavours. Just be aware that there are some sweetened varieties that contain lots of sugar – try to avoid these.

Soy products

You can pick up cheap soy mince, either frozen or dried, in every supermarket nowadays. Low in fat but high in protein, it’s a perfect alternative to meat for your spag bol or chilli. Add some beans or lentils for some extra protein and texture (check out the chili in our sample day of vegan meals if you need recipe ideas).

Tofu, which is made from soy milk in a similar way that cheese is made from animal milk, is considered a complete source of protein as it contains all the essential amino acids required by the body. A small 100g serving contains just 70 calories, broken down into 2 grams of carbohydrates, 8 grams of protein and 4 grams of fat. It has a number of health benefits – for example, it has been shown to boost heart health and reduce the risk of some cancers as well as diabetes.

Tip: tofu tends to be pretty overpriced in supermarkets. Instead of picking it up at your local Tesco, head to an oriental supermarket where it will be a fraction of the price. Plus, you can pick up some cheap soba noodles and edamame at the same time, to cook up a protein-packed stir fry. Bonus.

Tip 2: opting for firm tofu means you get more soya bean and less water, and therefore a higher protein content. Softer versions are great for making tofu desserts, but for acting as a meat substitute, it’s the extra firm variety you want.

Like tofu, tempeh is also made from soybeans, but is fermented into a firmer and denser food than tofu. As well as undergoing less processing, it has more protein, fibre and vitamins and less fat than tofu, so it is slightly healthier – but it tends to be harder to find and more expensive.

Other veggie “meats”

The last 12 months have seen veganism explode in the UK, with 7% of the population now following a plant-based diet (up from just 1% in 2016). Brands have been forced to respond, causing not only a steep rise in the availability of soy-based products, but also the appearance of some more creative options, like seitan. Made from wheat gluten, it’s 75% protein which is pretty impressive.

Hemp

The seeds of the hemp plant (not the leaves) can be used to create protein powder, with one scoop providing about 10 grams of veggie protein. It has a somewhat earthy flavour, so one of the best ways to use it is in baking – try adding to healthy brownies or protein balls for a post-workout treat.

You can also buy hemp hearts (hemp in seed form), three tablespoons of which contain 10 grams of protein with all essential amino acids.

Protein powders

While you can easily get sufficient protein on a vegan diet without using protein powder, depending on your goals it may be useful to incorporate some into your diet. There are loads of options to choose from when it comes to vegan protein powder – we’d recommend one that uses a blend of different sources as it’s more easily digestible (e.g. a blend of pea, rice and hemp protein).

Fitness Lab recommends:

Protein Works: Extreme Vegan

A mixture of soy, hemp, pea, rice and sunflower seed proteins, this protein is available in a wide variety of flavours and packs in a powerful 24g protein punch per serving.

My Protein: Vegan Blend

Made up of pea, rice and hemp protein, this is good if you’d rather avoid soy. It blends well and offers 22g of protein – and thanks to My Protein’s near-constant promotions, is one of the cheapest options available.

Vega: Clean Protein

This is a little pricier, but if you’re looking for the most natural, organic vegan protein powder, then this is the one for you. Available in chocolate or vanilla, each serving provides an impressive 25g of protein.

Protein requirements

In line with government guidelines, the NHS recommends an intake of 50g of protein per day for the average person eating 2,000 calories. This is incredibly easy to achieve on a plant-based diet – as you can hopefully see from the blog! If you do regular exercise, are trying to build muscle, or want to drop some body fat without losing hard-earned muscle, then you may need some more protein – depending on your goal, this could range from 0.8 to 2 grams of protein per kilo of body weight.

Sample day of meals

We’ve put together an example day of plant-based meals and snacks, to show you how easy it is to get adequate protein on a vegan diet. As mentioned above, your macro targets will vary depending on what your goals are – it’s a good idea to chat to a trainer about this.

Sweat Away Stress

According to a recent study, 85% of Brits experience stress regularly, with more than a third of us feeling stressed for at least one full day every week. There are a million different reasons that someone might suffer from stress, with common triggers including financial worries, pressure at work, relationship difficulties and health concerns. It can hit us at any time, but as April is Stress Awareness Month, now is perhaps a good time to identify the source of stress in your life and explore strategies to combat it.

Many people use exercise as a way to fight against stress. The rush of feel-good endorphins that is released by the pituitary gland during exercise can act as a major mood boost (ever heard of the “runner’s high”?). Not only do they make us feel happier, endorphins, also known as the body’s natural painkiller, have been shown to moderate our appetite (reducing the temptation to comfort eat when we’re feeling stressed), release sex hormones and enhance the functioning of our immune system.

It’s not just the release of endorphins that makes exercise great for combatting stress. Focusing all of your energy on your body’s movements can help you to forget about daily irritations or worries – you’re likely to feel much more optimistic after thinking about something else for a while, instead of dwelling on what has caused your stress and getting caught in a negative cycle of thoughts. Stepping away from a problem and focusing your energy on something else can sometimes open your mind up to a solution you might not otherwise have thought of, too – a change in perspective can sometimes really help.

What’s more, with regular practice of any sport, you’ll see yourself making improvements, which is a great confidence-booster and something positive to focus on when other areas of your life may be causing you some stress. When you’re feeling overwhelmed it can be tempting to isolate yourself, and while it’s true that spending some time alone can sometimes help to restore some calm, getting out and being active is one of the best ways to reduce stress.

Working out is a fantastic way to combat stress, but the most important thing is to find something that works for YOU! Above all, be kind to yourself – we all have bad days after all.
