Different stokes for different folks! What works for some, doesn't suit others. I've tried everything from the banana diet to the low-carb but then I should have listened to my mother! I learned.
My Mother always said, everything in moderation, so when I feel too big for my clothes, I keep eating normally, my usual, but HALF the amount! Works every time and I never miss any food that, by rights, I shouldn't be eating. Doesn't need any will power, calorie counting, or total mental absorbsion about FOOD - just eat slower, chew longer and halve the intake. You can go full serve now and again - eg; when eating at a friend's dinner party. Choose wisely at a Restaurant and you won't have to leave half!
Good luck - don't be miserable because of food!
