I found an approach to pizza. I eat the toppings and throw away the crust. That seems to work pretty well. I can eat a large pie by myself. In fact that is the inspriation for my recipe for “Brian (BSC)'s Pizza Pie Pie.”
ps. The high fat content of pizza delays significantly the digestion of pizza making it particularly challenging for us. That is also why you can still be digesting it the next day and have a high blood sugar.
