Healthy, Long-Term Weight Loss

Within 2-weeks at Pritikin, studies show guests reduce their body weight & waist circumference. Obesity is associated with a variety of chronic diseases, including hypertension, diabetes & certain cancers.

The most comprehensive study of long-term weight loss ever conducted, the National Weight Control Registry, found that the vast majority of its nearly 4,500 successful people followed a program, like Pritikin, that involved daily exercise & an eating plan low in fat & high in fiber-rich carbohydrates, such as fruits & vegetables. The members lost, on average, 66 pounds & at a 6-year follow-up they had kept it off.8
