Reading through these comments is scary. And I'm lucky. I've never put on weight in my life but always been active. 50 now and still snowboard, scuba dive and martial arts three times a week. Only ever ate two meals a day (lunch and dinner) and have never paid attention to sugar. Drink fewer sodas than I used to but still average about one a day. I eat a lot of meat but also a lot of vegetables and bananas. Maybe 50/50 meat/veg. Guessing metabolism has a lot to do with it. Nobody in my family ever got obese either.

The upshot is that what works for Peter may not work for Paul. And somehow I fell into a healthy lifestyle...
