About one hour after I lifted I ate dinner which consisted of two chicken breasts and a sweet potato. I would think that would be more then enough to satiate me for one meal. But sometimes post workout I will eat an amount of food such as that and my stomach will still have that hungry feeling. Does that mean that I need to eat more? Or is that empty feeling insignificant. I was thinking that maybe since I didnt eat any fat that might be the reason but I've never even heard of your stomach craving a specific type of calorie. Any food chemists out there? Help me out.
