IMO it is all about portion control and exercise. I agree that one needs the willpower to avoid their trigger foods, but depriving myself of all the things I love to eat is also setting myself up for failure. I have found that if I crave...I cave. Therefore, WW works for me because it is teaching portion control. It isn't a "diet" but a way of life. I agree that a quick initial weight loss is a great motivator, therefore, I agree that Atkins like diets help in that regard. That is why I like to do a combination of WW and the BFD. Basically it is eating healthier...low fat and low carbs.... and as long as I stay in the point range, I can have a little treat occasionally. I just can't binge and I have to get right back on track. I am no stranger to weight control...in fact, I could teach WW classes, which I might do after retirement.
