I get the same reaction to what I eat from my "regular" friends, no matter that it's no specific diet. Everyone is always watching my plate. At work, it's a lot of "You make your lunches? Oh, no wonder you're so healthy," and blah, blah, blah.
And they wonder why I don't give any reaction when my really good friend and her husband, who are both grossly overweight tell me they are going on the "fat flush" diet. Her husband lost about 30 pounds on this 2 years ago, and was making great progress when he just stopped. My friend believes that eating only grapes all day makes her lose weight.
Oy.
