re: Is there rehab for sugar addiction? If not, there should be.

I did it by increasing my protein to 1 g per pound of body weight at a minimum and often more than that. That will take away the hunger. From there just start eating low-carb and cutting out added sugar.
When you get good at that begin by cutting out sugars. Period.
At that point I was doing what’s called dirty keto where I was eating foods that had artificial sweeteners particularly Allulose. I did that for a while and then one day I decided to do carnivore because I really only had to cut out a little bit of what i was eating. So I’m doing carnivore and it’s really going well.
