Ames: I hate to inform you of this, but…I heard that diet sodas do not help in weight loss. The reason is: when you consume something that is sweet, whether it has calories or not, your body will react with an increase in insulin. The increase in insulin causes you to be hungry, and when on a diet, the last thing you want is an increase of appetite.
Perhaps one of the other very educated/informed posters will disagree, and I may be wrong, but this is what I heard.
So bottom line is that Kapusta is right. Stick to ice water or I like seltzer.
