A little over a year ago I was saying the same thing - I want to lose 20 lbs. But counting calories never worked for me for very long (5 lbs max). Check out
Beyond Diet I followed most of the eating plan, lost the 20 lbs, and have kept most of it off. I also believe that everyone is not the same. My husband has used a "no carbs" plan before, but I cannot live without carbs. BeyondDiet teaches you how to eat proper, balanced meals for YOU, while eating healthy food. Weight Watchers is another good plan, as you get the needed support to continue a weight loss regime. We're not 20 years old anymore, but we can still have a healthy weight and feel good about how we look. Good luck to you.
