Food Cravings and Your Metabolism

All right, but what is it about the metabolism that makes us want one food over another? It's the fact that we use food not just for nourishment but for its mind-altering effects. What each of us is looking for in food is a particular change in our state of mind. We want the food that wil make us feel both calmer and more awake. We've all had the experience of eating more than we really want; what's usually going on is that we keep putting food into our mouth, hoping to find the food that will make us feel really good-tranquil but alert, awake and yet calm. What is the relationships between the biochemistry of food, the state of the brain, and the psychological effects we actually experience? This idea, in fact, helps explain not just why we eat things we 'know' we shouldn't, but why we do any number of actions that we also 'know' are unhealthy. Each body type, then, is looking for this state of restful alertness from food. But, characteristically, each type of metabolism is set up to create restful alertness in itself by a particular set of biochemical reactions. Next: how to get restful alertness from food for each body type.
