I have been using the Weightwatchers plan for 18 months. I have now lost 5st. 13.5lb. Weighing food is now second nature. If you like flexibility then I would wholeheartedly endorse this diet. You can eat what you want, when you want as long as you don't go over the points. I use their calculator when I shop for pre-prepared food. That way I know I am not buying anything that will take me over the daily points allowance. If you don't have much money the I suggest you use the on-line method. This method really works but, as with all diets, you have to stick with it to get the full benefit. My advice is that you can get better products in the supermarket than buying weightwatchers products and they are cheaper too.
