|AB loves his oily fish.|
It might be obvious to some AB fans that he's lost some weight lately (Mary Beth thinks too much). Anyway, here's a short video that explains how he did it--using a number of lists of things to eat: every day and at least 3x/week and, maybe the hardest, 1x/week. And, of course, the list of things not to eat at all.
I guess you have to watch the full Good Eats episode to find out the "whys", but his ideas are always based on science and probably work if you follow the rules. I really should try it.
