When you exercise, your body works hard to supply energy to your muscles. That energy comes from what you eat – before, during, and after your workout. Eating well isn’t just about choosing healthy foods; it’s about eating the right things at the right time. Here’s a guide to help you stay energised throughout your session and get the most out of your effort.

Before Your Workout – Build Up Your Energy

What you eat before training has a big impact on how you perform. Your body needs fuel, and the best source comes from carbohydrates, which can be quickly converted into energy.

• Have a main meal 2–3 hours before your workout. Try a bowl of porridge with milk and fruit, a wholemeal sandwich with eggs, or a portion of pasta with vegetables and chicken.
• Add a small snack 30–60 minutes before. A banana, a handful of nuts, or a yoghurt can give you an extra energy boost without feeling heavy.

Avoid very fatty or high-fibre foods right before training – they take longer to digest and can cause discomfort while exercising.

During Your Workout – Keep the Energy Flowing

For shorter sessions under an hour, you usually don’t need extra fuel as long as you’ve eaten properly beforehand. But for longer or more intense workouts, your body can start to run low on carbohydrate stores.

• Drink water regularly. Even mild dehydration can affect your performance.
• For sessions lasting over 60–90 minutes: Consider taking in quick carbohydrates – for example, a sports drink, a piece of fruit, or an energy bar. These help keep your blood sugar stable and prevent fatigue.

Listen to your body. If you feel dizzy, nauseous, or suddenly tired, it may be a sign that your energy levels are dropping.

After Your Workout – Rebuild and Recover

After exercise, your body is ready to rebuild muscle and restore energy stores. This is when recovery begins, and the right meal can make a big difference.

• Eat within 30–60 minutes after training. A combination of carbohydrates and protein is ideal – for example, a smoothie with milk and berries, wholegrain toast with cheese, or Greek yoghurt with fruit and oats.
• Drink plenty of water. You lose fluid through sweat, and it’s important to rehydrate.
• Have a balanced meal later in the day that includes vegetables, whole grains, and a good source of protein such as fish, chicken, beans, or eggs.

Match Your Food to Your Type of Training

Not all workouts require the same kind of fuel. A 5K run demands something different from a strength session or a long bike ride.

• Endurance training: Carbohydrates are especially important, as they’re your body’s main energy source.
• Strength training: Protein plays a bigger role in muscle repair and growth.
• Light exercise or yoga: A small meal before and after is often enough – focus on hydration and balanced nutrition.

The key is to find a rhythm that suits your body and activity level.

Don’t Forget Hydration – The Overlooked Energy Source

Water is one of the most underrated factors in exercise performance. Even a small fluid loss can lead to reduced concentration, fatigue, and cramps.

• Drink a glass of water 1–2 hours before training.
• Take small sips during your session, especially if you’re sweating a lot.
• After training: Drink until you feel rehydrated – ideally alongside a meal.

If you’re exercising in hot weather or for a long duration, a sports drink with electrolytes can help replace lost salts and minerals.

Listen to Your Body – and Find Your Balance

There’s no single perfect eating plan that works for everyone. Age, gender, training type, and goals all play a role. Some people need more energy, others less. The most important thing is to pay attention: if you feel sluggish, heavy, or low on energy, it might be time to adjust what and when you eat.

Eating right during your workout isn’t about strict rules – it’s about giving your body what it needs so you can perform at your best and feel good while doing it.
