The only diet that has worked for me involves looking at the type of food I am eating. Highly processed foods do not satisfy me, and I just eat more and more. I only lose weight if I eat whole foods and avoid processed foods. That's just me, but I avoid WW for that reason. I just don't like the idea that eating WW branded processed food is any better than other processed foods.
When I chose whole foods I just feel better about what I am eating, and I feel satisfied and at peace with what I am putting in my body. Its morning here and I just made some oatmeal with blueberries and a sprinkling of ground linseeds and chopped almonds. No doubt someone would tell me there are too many points in it, but my tummy is happy and I know I won't feel like snacking.
Good luck with your weight loss. It is hard hard work and you need to find what will be effective for you.
