So, let’s start by talking about why you should be eating pre-workout, i.e. before a workout. Many people carry out what’s called fasted cardio, in an attempt to burn and lose body fat but in reality you need to fuel your body before each and every workout.
Ultimately, you should picture your body like a car – you can’t expect to drive 150 miles with no petrol in the tank, can you? If you’re looking to perform and train at your best, you need to make sure your body has enough fuel to do so. If you fail to provide yourself with the energy and nutrients required during exercise, the chances are you won’t see results as quickly as you should. Plus, over a long period of time, the likelihood of becoming ill or injured will be increased.
What are the benefits of eating before exercising?
Our bodies use carbohydrates and glycogen as the first source of fuel. This is because carbohydrates and stored glycogen can be converted into ATP (adenoise triphosphate, i.e. energy) faster than protein and fat. Therefore, filling up your glycogen stores pre-workout will mean you’ll have more energy to perform at your best.
Prevents Muscle Catabolism
When we exercise, glycogen stores are quickly used up and depleted, so the body looks for new sources of energy – our muscles. By breaking down hard-earned muscle, the body can utilise amino acids for energy. This is bad, as it puts our bodies into a catabolic state, which can prevent muscle growth and recovery.
Increases Muscle Anabolism
Eating the right foods pre-workout means you won’t only top up your glycogen stores, but by eating a good source of protein, you’ll also be able to promote muscle-protein synthesis and create an anabolic environment in the body.
What are the best foods to consume before a workout?
Pre-workout, it’s best to avoid too much fat. This is because, although high in energy with 9kcal per gram, fats are slow-digesting. This means, instead of making you energetic, they can actually make you feel sluggish and heavy.
Pre-workout meals containing protein provide us with a major benefit – the prevention of muscle catabolism. By consuming a good source of protein before a workout, you can give your body the amino acids (branched-chain amino acids in particular) that it needs to prevent muscle breakdown, whilst aiding muscle recovery and growth.
There are two types of carbohydrates: simple, high glycaemic index carbohydrates, and complex, low glycaemic index carbohydrates. But which one is best pre-workout?
This ultimately depends on your goal and the time of your pre-workout meal. Simple carbohydrates are great for 30 minutes to an hour before a workout, as they provide the body with fast-acting glucose as fuel. However, complex carbohydrates also play a role within energy metabolism. By consuming low GI carbohydrates around 2-3 hours before a workout, you can give your body a slow-releasing source of energy. This means you’ll be able to work out for longer and be less likely to have a dip in your blood sugar levels in the middle of your workout.
30 Minutes to an Hour Pre-Workout:
Consume light meals and foods which contain simple carbohydrates and some protein.
2-3 Hours Pre-Workout:
Consume a meal around 400- 500 calories containing a good source of protein (around 20g) and complex low GI carbohydrates (20-30g).
