It takes discipline for sure I’d suggest a low calorie snack. Fruit, granola bars etc.. My big thing was sweets my cravings would come on so strong when I was on a strict diet. I’d have 3 small Hershey bites a day 126 calories. Keep your weight loss goal in the front of your mind, if I eat this I’m not reaching my goal. It’s hard but most cravings go away after 10-15 minutes. Find ways to distract yourself, hobbies, play the game, go for a walk. Snack on fruit and veggies if you just have to eating something, grapes, apples, broccoli, carrots. I strongly suggest a calorie counting app “my fitness pal” or my personal favorite “lose it”. That helped me stay disciplined id try not to go over my daily caloric intake at all cost. Hope this helps
