Fruit does this to me which is why I have removed most of it from my diet, I end up eating too much of it and worse I end up wanting to snack other stuff afterward.

if I stick to meats and vegetables, mostly green kind, I don't have the munchies but I have to tend more to the "keto" side to keep it up. Meaning, no starches or sugars but lots of fats and green stuff; that was the key for me, lots of stuff that is green.

yeah there is science behind nearly every diet but the trick is finding out what works for your physically and mentally. Forget to accommodate the mental side and its easy to lapse
