i'd like to offer ways to combat your affliction, but sadly i do not believe there is one. i do use an artificial sweetener, but very little (< 1/4 of the amt that i see used in tests that see if artificial sweeteners trigger an insulin reaction) and only in coffee and iced tea. if i were to use the amount needed to make a batch of cookies, i believe it would be both antiproductive and dangerous. sugar gives your blood sugar level an immediate boost, your body generates a huge amount of insulin in an effort to lower your blood sugar and then your body is left with an even greater need for another sugar boost do deal with the insulin level. you are trapping yourself chasing your tail and the only outcome is that your high blood sugar level gets turned into fat stores. it's a lose, lose (figuratively) situation.
the suggestion that you "only eat a little once in a while" i know for a fact does not work with me. the very few times i have had a "little sweet treat", the hunger pang i got in 2-3 hours was huge. fortunately i got through it, but it's now something i know i won't enjoy and almost always pass on the urge.
i do make up snacks, but they average <200 calories and at most contain maybe 10 gms of sugar, but typically are more in the 5-6 gm range. i also make sure i have these within my daily eating window and usually toward the end of that time (i intermittent fast daily).
just because sugar is legal and heroin is not, does not mean it is not as addictive or dangerous to your health. the sugar industry just has better lobbyists.
