Objective: Not to regain the weight you've lost!
How: By continuing to eat lots of low calorie density foods. Eat at least one meal a day made up entirely of low calorie density foods. At the other two meals, mix low and medium density foods. Avoid high density foods as far as you can, especially refined ones (sweet and savory snack food, cakes and pastries, chips, burgers, quiche etc).
