Weight Watchers is all about how to lose weight and still have all the disorders of hyperinsulinemia. So it's not all about losing weight. To my mind, low carb eating is far easier and more satisfying than any low fat regimen with its tasteless uninteresting food.

People who tried to get into low carb eating by using low carb substitution products were doomed to failure. Whole, fresh foods are far better than all that stuff. The only low carb substition product I use regularly are the Tortilla Factory low carb tortillas.
