I had to comment about the Vita Mix. If I have a fruit smoothie every morning it is easy to keep the weight off. The smoothie keeps my hunger in check until about 1 o'clock. It's the easiest way for me to keep weight off.
My smoothie is usually whatever fruit I have fresh and then I add frozen berries, and fruit juice, sometimes a little water. I make a large glass, about 16- 20 ounces. It's easy and it tastes good and it's good for me. Dieting is not easy, but this is.
