Very hard about a diet. My 2 cents, most of the time people aren’t hungry they are dehydrated. Carrying a water bottle constantly full helps. For snacks I try to stick to stuff with protein and very little sugar and lower carb (still need some to fill you up.) sweet potatoes are an awesome thing fhat will help get the carbs. Beef jerky, nut mix, peanut butter, protein bar, powder, small thing of steak/chicken, plain can of tuna etc. plain Greek yoghurt, (toss in a couple blueberry or strawberries if you can’t stand plain yogurt. usually as long as it had a good amount of protein at a good calorie point. Calories are more important than worrying about carbs and fats only because your body needs a little of everything. And most of the time the water trick is really what is the hunger. Just my two cents from an armchair dietician. ( my sister an Actual dietician with a masters would KILL me as she deals with dorks like me all the time who think they know a bit, though she does agree on the water part not so much the almost no carb/Keto diet which is supposedly awful for people.
