A calorie is a calorie, the advice goes. Eat too many ... gain weight. Eat fewer ... lose weight. But many believe weight loss is more than a calorie equation, with so-called new-and-improved ways to lose weight being ever popular. Americans spend an estimated $42 billion annually on weight loss foods, products, and services. With that much money at stake, it's no surprise there is an overwhelming number of "fad" diets and other weight-loss products on the market.
Having so many diet options makes it difficult to know which ones to trust. For this reason, The Partnership for Healthy Weight Management has developed the "Voluntary Guidelines for Providers of Weight Loss Products or Services."
The mission for these guidelines is to "promote sound guidance to the general public on strategies for achieving and maintaining a healthy weight." According to the guidelines, effective weight management involves:
Behavior modification that includes:
- Dietary intervention
- Healthful eating in accordance with the Dietary Guidelines for Americans
- A reduction in calories
- A lowered fat consumption
- An increase in fruit, vegetable, and whole-grain consumption
- Physical activity
- Increased frequency
- At least moderate intensity
