If thats the case, wouldn’t anything with a sugar substitute do that too?

I have a theory for weight loss, I don’t know if it works or what damage it might (c’v) do but I’ll throw it out for discussion anyway. (Do it at your own risk- totally not recommending.) Watch one thing; Calories, fat, sugar (simple carbs), salt and eat reasonably well in the other categories.
Also keep in mind that in general, losing weight is easy, keeping it off is hard. Whatever diet plan you try needs a (healthy) cheat system in place otherwise you’ll be off it in a week or two.
