I am one of the lucky ones, I don't have any hunger 27 days out of 28. I find if I eat 4 or 5 small meals a day works well. That way I can get all my necessary food groups in. Pasta, bread, and potatoes are off my menu, no tolerance of them yet. It has taken me almost a year to master this as I was on really low calories for a long time due to severe restriction and nausea. I can manage to get in 1000 to 1300 calories a day this way and all my protein requirements
Breakfast will be a protein yogurt
Mid morning a small glass of milk
Lunch is usually homemade soup, veg, lentil, mushroom, Thai style or Pho
Mid afternoon - a piece of fruit and a small piece of cheese
Evening meal - meat and salad or vegetables
On my hungry day, I don't let my calories get above 1500 by eating lower calorie foods than on other days
