Great, after eating a lowfat, sugar-free frozen yogurt last night, I learn this:

It sounds like an oxymoron but low-fat yogurt may be more fattening than you think—at least for some people under some conditions. That is just one of the counterintuitive ideas behind new research to study the effects of a physiological condition known as insulin resistance in driving weight gain and obesity. Depending on what investigators find, some pretty conventional beliefs about what ultimately is fueling the current global epidemic of obesity—calories or carbohydrates—may need a bit of readjusting.

I already know this stuff, but when I see it in print, it really hits home: I need to stop eating this junk. But I have a horrible sweet tooth. Any suggestions, other than “stop eating that junk?”
