Energy food

winston eat plenty of carbs in the morning and lunch, none at all for dinner and no fats either....have a big dinner of veggies (not potatoes) and protein...as early as you possibly can...worked for me.

what he said. unless you're going on an all day ride, in which case eat carbs the night before.

if you're snacking during the day eat crunchy food with virtually no energy content (rice cakes, celery, carrots, cucumber) - crunchy stuff makes you feel like you're eating even if you're not actually taking in much in the way of carbs.

If you need a boost, eat fruit - the sugars are absorbed slower. Refined sugars hit you quickly and give you a brief boost, but then they leave you feeling slumped and listless when they wear off. They may be helpful if you're racing but even for training I reckon bananas are a better bet than powerbars. I have a soft spot for dried dates and apricots, personally.
