The GI Diet isn't low carb, it's pretty high carb.. There are tons of grains, fruits, veggies, and even pasta.. I also have intense sugar cravings but I've determined that it's 100% mental. My head is telling me I need sugar, not my body. In my opinion, it's just not possible for your body to tell you that you need more simple carbs. We don't need simple sugars -ever.. I've heard that when you've done the GI thing long enough (a few weeks) without giving in to the sugar cravings, the cravings just disappear.. I've never gotten that far though..

What I've done to deal with these cravings is first not keeping any in the house. If I really want something I'll have to get off my butt and go get it. And if I do go and get something, it's one thing. It can be anything I want but once it's gone, it's gone and that's that. Maybe you could do something similar by just buying 1 donut, instead of a whole box?

I am on a very low-carb diet.

During recovery my body has a craving for L-Glutamine. As long as I satisfy it I have no problems.

It is probably the feeling that people on high-carb diets get and they think it can be satisfied with sugar. Obviously not if you have to eat 6-12 donuts and probably feel like you could eat more.
