I thought some studies had found that artificial sweeteners can still fuck with your body's insulin response or blood sugar spikes or something like that? That they can actually stimulate appetite or cravings?
In any case, I think it's kind of part of the whole self control thing. You know who drinks the most diet soda? Fat people! Because they constantly need to be consuming extremely flavorful, salty, sweet, savory foods. They've trained their taste buds and psychology to crave that kind of shit. Breaking those kinds of habits, in my opinion, is a big part of maintaining a healthier diet and lifestyle. For me it's pretty easy to stay away from that shit, as I find some artificial sweeteners upset my stomach and/or give me the shits.
