If you're not looking at it from the point of view where weight is about the food you eat, and health is about the exercise you get - you're bound to run into trouble at some point.

The only way to control your weight is to control your diet. It doesn't matter what your basal metabolic rate is. Will it play a role? absolutely, but it's not what you adjust to keep your weight in check. If you can manage your weight with a low metabolic rate, you can manage it with a high metabolic rate. Gaining muscle mass will make your body signal for more food, so it can be counter productive if you want to lose fat.
