Hello. I know I'm writing this months after your post, but someone just pointed me to it. You have a lot of good information here; the kind of stuff you rarely see all in one place. Thanks for putting it together.

I had one question I was hoping you could answer. You state, "Doing fifteen minutes of aerobic exercise will raise your metabolic rate for quite some hours afterwards. This overall raise in metabolic rate is likely to burn more energy than doing fifteen minutes of fast running, after which your body collapses and reduces your metabolic rate for hours afterwards." I had never heard this before. Could you tell me the physiology behind why your metabolic rate would drop? (I've been trying to determine the exact reasons why aerobic exercise is better for weight loss than anaerobic, but nowhere can I find an actual scientific reason.)

Thank you.
