A trick I've learned is to eat just a little bit of something that has no carbs and no sugar in it before you go to sleep because it keeps your metabolism going. ↗
I drink protein shakes nonstop - three or four a day - and I run a lot, so you get rid of the bad carbs and keep the rest so you have the energy to make it through. ↗
I have a chef who makes sure that I'm getting the right amounts of carbs, proteins and fats throughout the day to keep me at my max performance level. ↗
