I've spent a lot of time "researching" the whole diet/nutrition thing over the past several years. There's enough information out there to justify anything you want to believe. It boggles the mind. I've come back to where I started.....eat whole foods, eat less, exercise regularly. And, at 73 although I weigh 187-190 (pretty much what I weighed playing football in college) I am 2 1/2" shorter and about 1-2" thicker in the waist. Probably some of this is down to 3-4 oz of bourbon in the evening. Some of it is about aging. What this comes to, for me, is "Are you healthy? Are you enjoying life?" I am.
