Unless you can show that low calories sweeteners are directly responsible for weight gain; i.e. somehow the sweeteners affect how food is metabolized, fat is stored, etc., then these studies don't really say much other than people who are unable to control their appetites are unable to control their appetites. Low calorie sweeteners are still a better option than sucrose with respect to flavoring. In terms of annecdata, I've been trying to control my father's eating habits for years now (due to his numerous heart attacks and double bypass), and while I've not been completely successful, everything about my father's health has improved since he switched to diet pepsi from regular pepsi and since I got him to stop buying sugar for his coffee, convincing him to go with Stevia instead. He still sneaks junk food, but that's not something that has changed. His blood sugar has decreased and his joint pains have improved. To a certain extent, studies like this that make recommendations against recommendations seem irresponsible.
