For me, eating more sweet stuff and refined/°processed foods is a big part of what enables me to stick to the diet and avoid animal protein and fatty foods, especially since I usually don't eat much sweets/junk and DO eat high fat. So it's like a consolation prize - if I can't have the super healthy fatty/protein foods I crave, at least I can have the mostly empty cals sweet junk that used to be a rare treat.
