What to eat before training: the basics, without the hype

Eat carbohydrate, drink water, and don't overcomplicate it. That is what the evidence supports on what to eat before training, and it is less complicated than most plans you will find out there. A recent review from the British Nutrition Foundation is clear: carbohydrate is the main fuel for the brain and muscles during exercise, and eating too little carbohydrate when you train can leave you with low energy, poor concentration, dizziness or irritability. If you only have two minutes, hold on to those three things.

Now the part nobody likes to hear: what you eat before training is not the only factor at play. If you train recreationally, you can generally follow healthy eating guidelines and base your meals on carbohydrate, according to the British Nutrition Foundation.

Why carbohydrate is the piece that really counts

Think of carbohydrate as firewood and training as the stove. Without wood, the stove doesn't heat, however good the recipe. The British Nutrition Foundation describes carbohydrate as the key fuel for the brain and muscles during exercise.

What happens when you eat too little? The same source describes concrete consequences: low energy levels, poor concentration, dizziness, irritability. None of this is dramatic in itself, but the British Nutrition Foundation notes that a very low carbohydrate intake during exercise can cause these symptoms.

And the reverse? The message is not that eating more carbohydrate turns anyone into an athlete. The British Nutrition Foundation says that people who are active at the recommended level of around 150 minutes of moderate activity per week can follow general dietary guidelines and base their meals on carbohydrate, choosing wholegrain and higher-fibre options where possible. Only for athletes and those training at a higher level does it say that additional carbohydrate may improve performance, and that it is a good idea to have some before and after exercise. This matters. What you eat should depend on the frequency, type, duration and intensity of the activity you do.

Which foods actually work, and in what amounts

The British Nutrition Foundation lists examples with their carbohydrate content: wholemeal pasta, couscous, brown rice, baked potato, wholemeal bread, banana and oatcakes. Notice the pattern — these are ordinary foods, not branded supplements or sports-shop products.

The amount, though, has no universal number. The same source says it depends on the frequency, type, duration and intensity of the activity. That means any table giving you exact grams without asking how you train is guessing. A thirty-minute walk and a two-hour weights session do not call for the same thing.

If you want a practical rule without inventing precision that doesn't exist: start with a portion of one food from that list, see how you feel in the next session, adjust. Half a banana more if you ran out of energy. Less bread if you felt heavy. That is how you calibrate, with your body as the measuring instrument, not a calculator.

Protein: the myth that steals the place of carbohydrate

The idea that eating lots of protein gives you bigger muscles is, in the words of the British Nutrition Foundation, a common myth. Most people can meet their protein needs with a healthy, varied diet, and focusing on protein may mean not eating enough carbohydrate — which is the most important energy source for exercise.

We are not saying protein is irrelevant. We are saying the pre-training plate is not the place to put it first. A protein shake before training, when what was missing was bread, is money and effort in the wrong place.

If you train seriously and want to adjust protein and carbohydrate in a personalised way, seek a qualified sports nutritionist or dietitian. The British Nutrition Foundation recommends exactly that for professional athletes.

Water, and the question about energy drinks

The British Nutrition Foundation says drinking enough fluids is essential for performance and recovery, and that it matters to stay hydrated before, during and after exercise. The practical part many people ignore: unless you are training at high intensity for more than an hour, water is usually the best choice.

In other words: you don't need a sports drink for a forty-five-minute gym session. You need water, before and during. If you train for two hours at high intensity in the heat, the conversation changes — but that is not most people, and we are not going to pretend it is.

How to fit this into a real day, including breakfast

Here we are not going to invent timings, calories or macronutrient targets. Any article that tells you "eat exactly 90 minutes before" is filling a gap with an opinion dressed up as science.

What you can do, with what is solid:

• Base your meals on carbohydrate, choosing wholegrain and higher-fibre options where possible.
• Make sure the meal before training has carbohydrate, not just protein.
• Drink water throughout the day, not just when you get to the changing room.
• Adjust the amount to the duration and intensity of the session, not to a fixed number.

We know that carbohydrate counts and that the whole day matters. If you train at seven in the morning, try eating something with carbohydrate and see the difference in the session. If you feel uncomfortable with a full stomach, eat less and closer to your usual habit.

The mistakes that undo the habit, and the ones that matter less

The mistake that really undoes it: building the day around protein and leaving carbohydrate for the leftovers. The British Nutrition Foundation is explicit about that. Another real mistake: training fasted out of discipline, when the lack of energy and concentration is already noticeable — the same source describes exactly those symptoms with very low carbohydrate intake.

What the evidence does not fix: the exact time of the meal before training and the amount of carbohydrate suitable for each person. Neither is at the centre of the evidence. Variety and matching your effort are.

And there is a reading mistake worth undoing: the idea that the pre-training meal makes up for an unbalanced diet the rest of the day. It doesn't. The British Nutrition Foundation talks about a healthy, varied diet as the base, and says that eating well for physical activity can help performance and reduce the risk of injury and illness. That is a description of the overall pattern, not of an isolated meal.

Supplements: where they fit, and where they don't

The British Nutrition Foundation's position is "food first": supplements are generally not necessary for most active people. This applies to pre-training as much as to anything else. If your diet already has enough carbohydrate, a supplement won't fix what isn't broken.

If you are looking for information on creatine specifically, there are dedicated pages for that. What we can say, and it is factual: Creatine Gummies are taken at a dose of 3 gummies per day. They contain polyols, whose excessive consumption may produce laxative effects, and food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Keep out of reach of young children. They are intended for adults.

We have no label data for the Performance Pack, so we give you no amounts or composition for it. If you consider it, read the label.

If it is still not working after two or three weeks

First, define "working". If the goal was more energy in training and you still don't have it, check whether you are actually eating enough carbohydrate throughout the day — not just before the session. If the goal was weight loss, no pre-training meal solves that on its own, and we won't pretend it does.

Second, look at what changed and what didn't. What you eat before training counts, but so does the rest of your eating day.

Third, and here we are direct: if you have persistent symptoms of low energy, dizziness or irritability, speak to a qualified health professional. The British Nutrition Foundation recommends personalised advice from a qualified professional for athletes, and the same principle applies to any situation outside the ordinary. It is not a question of supplements. It is a question of knowing what is going on before trying to fix it blindly.

What to do tomorrow: put a carbohydrate food in the meal before training, drink water throughout the day, and don't add anything until that is sorted. If you already do that, you probably don't need to change a thing — and that is a useful answer too.
