Eggs and cheese are pretty easy to find so that can't be it. Plus if you've done a keto diet (I assume that's what is meant by getting over a "sugar addiction") for a length of time, the cravings are real, and sometimes interesting (e.g. craving things you haven't had or thought about for years even pre-diet). I think most people who have trouble getting on and sticking with a keto diet are more addicted to easy-access food variety rather than particular foods. They'll succumb to the easy-to-order pizza delivery in larger part due to its easy-to-order and being-something-different properties rather than the craving for pizza/sugar itself being too strong. Keto is easy if you don't mind the monotony of the same easy-access food for almost every meal, or enjoy cooking enough to make a large variety of food. If you do mind, that'll probably have to go first, sugar or no sugar.
