Getting dehydrated

‘Hunger and thirst are controlled by the same part of the brain, which can leave us confusing the two,’ says Rebecca. This is why we often have the urge to nibble post-workout.

SORT IT Hydrate with plain water. Drink 250-300ml 30 minutes before a workout, take small sips during exercise, and aim for 500ml–1ltr afterwards, rather than reaching for a snack. Avoid sports drinks unless you’re doing endurance exercise – some contain up to 150 cals.
