You are correct. I'm trying to regulate my unregulatable diabetic son, and cutting out artificial sweetners is part of the process. (He can still make small amounts of insulin.) The sweet taste does cause people to make insulin and (I would think) this would cause hypoglycemia in some. One symptom of hypoglycemia is incredible hunger. It would make sense to me that these folks would gain weight.
"One symptom of hypoglycemia is incredible hunger."
Exactly my thinking.
I've never liked artificial sweeteners because of their taste, and sugar is only 16 calories per teaspoon, so what's the big deal?
I am not a conspiracy kind of guy, but I am certain that a lot of pressure was put on the researchers to keep their findings quiet.
