Portion control actually works for weight loss.

Weight loss should be as simple as eating fewer calories ends in less weight on your torso.  Sure, it sounds so simple as not eat or drink too much, but, unfortunately, weight loss is not this simple.  This is why many of the worlds are now struggling with being overweight or obese.  In practice, it is too easy to eat or drink more than you have planned.  The question has always been how do we keep our servings eaten to the correct portion size.
