I'm an avid jogger(of 19 years), may favorite foods are healthy, often ethnic, always natural. But I eat too much. So I gain weight. Calories in, calories out-scientifically proven. Jenny Craig is so far the only program that reminds me of correct portions. I've been on it 3 times - each time I've lost over 20 pounds over 3-4 months. Now, if I could stick with those portions when I'm on my own!
