You already know the other levers you can push to stay healthy and
happy: Eat a balanced
diet, get enough exercise, and go easy on alcohol (which increases stress
hormones and suppresses deeper stages of sleep).
The Zone
diet can give people the false sense of security thinking that it is their
hormones at fault, they are
happy to hear that it's not their fault they're fat, «It's my
hormones that are the real culprit, I don't have to feel guilty about being a glutton and not exercising.»
