Weight Watchers has it right. The whole concept of weighing your foods to determine portions makes sense. If you weigh 145 lbs and consume 3lbs of food, you will then weigh 148 lbs until your body processes or eliminates what the body doesn't need. But who has time to weigh every morsel of food consumed or count points? Although if you do the results are worthwhile. In any case, much of our weight-gain malay comes from a lack of portion control and/or a lack of exercise. There is now dishware products on the market that takes the worry of how much is too much.
The way these plates, bowls and cups work is that vegetables are put where the largest round on the plate is, starches next largest round and the smallest portion is reserved for the protein source.
There are several companies that sell portion control dishware.
