My best little secret is how I lost weight and keep it off. It is very simple really, use a dessert plate instead of a dinner plate. Only take 1 spoon full of each item and 1 piece of meat each meal. No seconds. Cut down on starches and sugars. Eat more vegetables and fruits. You will loose weight.
I went from a size 14 to a size 8 and have stayed there for 6 or more years. I still eat that way and do not have junk food in my house. I will buy potato chips once in a blue moon once or twice a year. Hope this helps you. Good luck.
