Whatever fitness goals you have, nutrition is an absolutely critical component to success. Think of your body as a finely tuned sports car – you wouldn’t expect to win the Grand Prix if you filled the tank with cheap, dirty fuel! In the same way, there’s no point setting yourself challenging goals in the gym unless you’re also going to think about what you’re putting into your body.
The food we eat has a massive impact on our training, influencing both our performance and our ability to recover and grow muscle. Ever heard the phrase “abs are made in the kitchen”? There’s a lot of truth to it. You could spend hours in the gym trying to sculpt the perfect six-pack, but if your diet is poorly thought-out and leaves you with excess fat around your midsection, then your hard-earned abs will unfortunately never see the light of day.
For those with more specific fitness goals, or who are interested in delving a little deeper into nutrition to take their training to the next level, it can be helpful to consider the role that macronutrients and micronutrients have to play.
So, what are macronutrients and micronutrients?
Macronutrients are the building blocks of our diet. They provide energy in the form of calories and are used by the body to create energy, grow and repair tissue and keep all of our body’s systems running smoothly. They are required by the body in large amounts (hence the Greek prefix Macro, meaning large), and can be broken down into three categories:
Maintaining a consistent calorie surplus or deficit will lead to weight gain or loss, respectively. However, considering how much of each macronutrient you include in your daily diet can help you to meet more specific goals, for example by making sure that you are getting adequate protein to recover from your workouts and actually build muscle. So, roughly how much of each should you aim to be eating?
The idea that “carbs are bad” has been popularised by diets like Atkins and Dukan, however, it’s incredibly misleading to demonise one food source and claim that it will “make you fat” –any food can be fattening if you eat too much of it! In reality, carbs they are your body’s primary source of energy and as such should make up the most of your calories. Current NHS guidelines suggest that carbs should make up at least 50% of your calories. Fat shouldn’t exceed 30% of your intake, however shouldn’t drop below 15%, as this can lead to a myriad of health problems, including hormonal imbalances and digestive problems.
If you’re looking to build muscle, then checking your protein intake is a good idea. At least 15% of your daily calorie intake should come from protein, however people seeking to take their training to the next level will quickly realise that there are a lot of different opinions on the optimum amount of protein. It will largely depend on what your goals are and requires a process of trial and error to see how your body responds to different amounts of protein. It’s worth mentioning that protein satiates hunger, so if you’re embarking on a weight loss plan, it can be helpful to up your intake of protein to stay fuller for longer.
It’s not uncommon for athletes and fitness enthusiasts to dedicate a lot of time tweaking their macronutrient ratios, to achieve optimum results. This may be according to their personal experience of what works for them, or recommendations based on their body type or training goals. Some people subscribe to the “If It Fits Your Macros” approach, which essentially states that you can eat whatever you like, as long as it fits in to the ratios you have calculated to help you achieve your goals – so nothing is off limits, you can eat as much junk food as you like as long as it fits within your macros. While it’s definitely great to have a flexible attitude to dieting and not restrict yourself too much, common sense dictates that our body will not benefit from consuming our macros from processed junk food – this is where micronutrients come in.
Having a complete macronutrient profile is essential to support your body, however it’s important not to overlook the importance of micronutrients. Making sure that you hit your macro targets by consuming healthy, unprocessed foods means that you are also providing your body with essential vitamins and minerals, thereby fuelling your body in the best possible way to ensure optimal performance.
Micronutrients are essential substances that ensure the smooth running of our organs, nervous system, joints and ligaments. Critically, they also help to ensure efficient metabolism of macronutrients, which can help to maximise your results in the gym. They are only needed in tiny amounts (which is why they’re known as Micronutrients, from the Greek for small) and include the following vitamins, minerals and trace elements:
From the above list, it’s clear that by eating a wide variety of whole, colourful foods, you should be able to hit your micronutrient needs with ease, while also ensuring you get a complete macronutrient profile.
Temporarily tracking your calorie intake and macronutrient ratios can be a really helpful exercise. You may be unwittingly consuming more calories than you thought, for example, or not getting enough protein to help your body recover from workouts. Just a few days of tracking can drive your understanding of what you should be eating, so that eventually you can intuitively reach for the right foods. This isn’t something that you should feel that you have to do for ever, unless you want to. It’s great to just use it as a short-term strategy to help you understand what you are putting into your body and think about what adjustments you might be able to make to bring you closer to your goals.
Try not to get sucked in by diet fads and buzzwords – and although there’s a lot of information above, hopefully you can see that healthy eating is really not as complicated as the media sometimes makes it out to be! Just try to be mindful of how much you’re eating, and focus on filling your plate with a variety of wholesome, unprocessed and colourful foods that fuel and nourish your body. And as well as eating right, don’t forget to stay hydrated – you can find out why this is so important in our blog dedicate to this topic here.
