> So many diets talk about not being hungry while you are on the diet. I've been to dieticians and told them I'm hungry, and they suggest eating more protein or more fiber. That does help, but I still feel hungry.
Have you thought about eating something that just has very few calories, in order to fill you up? Carrots have barely any calories and need a fair bit of chewing. Popcorn without salt/sugar/butter as well. Diet drinks or water.
What's helped me a bit is just looking at all the calorie labels on everything to get a feel for what the cost of each item is, then using that as a kind of "is it worth it" budget. A lot of things go out the door when you do that, but surprisingly some quite nice things stay on the menu.
