Several months ago I ran into an old friend of mine at a health food store. She was there looking for Agave sweetner. Even though she works out like a maniac (seriously - like a maniac) and watches what she eats, she could not manage to lose any weight and so she visited a doctor. That doctor told her that one of her problems was using Aspartame sweetner and sent her in search of all natural sweetner. So even though women (and men) take the risk of eating and drinking what is basically formaldehyde (you know, the stuff they embalm dead people with), it apparently doesn't even help to lose weight. What a rip off!
Frankly, I had always wondered. Years ago, my sister who had a terrible coke habit, switched to diet sodas and other no sugar foods. She drank at least a 6 pack per day (though I imagine more than that) and you would think that switching to a diet soda and no sugar foods, since she really didn't eat much, would have caused her to lose a few pounds, but no.
