Sports nutrition does not have to be complicated. When you eat enough, drink steadily and recover properly, training usually feels more even and energy is more stable.
What matters most#
Regular meals, enough protein and enough carbohydrate around harder sessions are the main pillars. Fluids matter as well, especially when the training is long or the weather is warm.
Before training#
A light meal or snack before exercise often works better than training hungry or overly full. The goal is a calm stomach and enough energy.
During and after training#
For short sessions, water is usually enough. For longer or harder sessions, a drink with carbohydrates can help. After training, the next meal should bring back protein, carbohydrate and some vegetables or fruit.
Supplements#
Supplements can have a role, but they do not replace food, sleep or sensible training load. They are most useful when a specific need is clear.
When to seek care#
Seek care if fatigue becomes persistent, weight drops without trying, training tolerance falls quickly, or eating becomes difficult or stressful. The same applies if stomach symptoms interfere with exercise or recovery.
