I don't know what to make of that.
Well, I don't buy into the whole no adult should eat more than 2000 calories
thing, but this last part about your caloric intake looks like good advice, Kathie.
Your body doesn't just burn muscle mass when it doesn't get enough fuel - it takes from your organs and bones, too! Your brain only runs on glucose - or ketone bodies as fuel (if it's forced to.) Ketone bodies are formed when your body is metabolizing protein for fuel because there aren't sufficient carbohydrate sources available. That protein will either come from your food or your body (or both.) It places stress on your body and is counter-productive to the stoked metabolism that will help you meet your goals.
If you're starting an exercise program, you might want to add a bit more (even if it's just a small apple sliced up and smeared with some lowfat peanut butter - an hour before you exercise.)
