I was on no-carb/keto for 6 months. For a while I almost couldn't walk past the sweets section in the supermarket, but after a couple of weeks, I completely lost interest in it. I still had a piece of chocolate here and there, but I could just stop when I wanted to!
I'm still a little sensitive to sweet things. As a child I liked it but after keto it's not as appealing anymore.
Also, eating sugar makes my teeth feel really nasty.
