It seems there's some conflation on NSS and satiety vs. full sugar sweeteners. If you have the choice between diet soda and regular soda, drinking regular soda WILL make you gain more weight. The extra calories are the mechanism. What diet soda doesn't do, though, is provide any satiety benefit. Although regular soda provides very little satiety, I suspect it provides some small satiety, since it is still calories. If people don't get their 'cravings' in check, then you get overeating in other places, likely with other low satiety foods/drinks. In the end, it might be mostly a net neutral behavior if the other foods replacing the calories in soda are just as bad. This is mostly speculation, though. At the end of the day, dieting is hard work, so if you get to a weight that needs to be corrected, the fix is not easy...
