Many diet-and-exercise programs claim results, but where is the proof, the published results? Scientists from Harvard Medical School, Stanford University, UCLA and many other research institutions have lauded Pritikin's effectiveness to help prevent and reverse heart disease and other health concerns.

More than 115 studies in prestigious medical journals like JAMA, the New England Journal of Medicine, and Circulation have documented the Pritikin Program's extraordinary success in helping thousands worldwide. Discover what the Pritikin Program can do for you!

The Pritikin Program has been found to:

Reduce Total and LDL Bad Cholesterol 23%

Analyses of 4,587 guests staying at Pritikin for three weeks showed an average 23% drop in total cholesterol and 23% drop in LDL "bad" cholesterol. New England Journal of Medicine, 323: 1142, 1990; Archives of Internal Medicine, 151: 1389, 1991.

Reduce Triglycerides 33%

Analyses of 4,587 guests staying at Pritikin for three weeks showed an average 33% reduction in triglyceride levels. New England Journal of Medicine, 323: 1142 ,1990; Archives of Internal Medicine, 151: 1389, 1991.

Lower C-Reactive Protein 45%

In just two weeks, inflammation markers like C-reactive protein plummeted 45% in women at the Pritikin Center. No other diet-and exercise program or drug therapy, including statins, has proven to lower C-reactive protein so dramatically or rapidly. Metabolism, 53: 377, 2004.

Lower Insulin Levels 46%

In three weeks, insulin levels fell 46% in men at the Pritikin Center. Circulation, 106: 2530, 2002.

Alleviate the Metabolic Syndrome In Adults

Having the Metabolic Syndrome, a condition now epidemic in the U.S., puts one at major risk for diabetes and heart disease. In about 50% of men studied, the syndrome was not only controlled but also reversed after just three weeks at the Pritikin Center. Journal of Applied Physiology, 100: 1657, 2006.

Alleviate the Metabolic Syndrome In Children

Among children with the Metabolic Syndrome, 100% no longer had the clinical diagnosis of the syndrome within two weeks of starting the Pritikin Program. Metabolism Clinical and Experimental, 55: 871, 2006

Lower Heart Disease Risk Factors In Children

In two weeks, overweight children in the Pritikin Family Program decreased LDL bad cholesterol on average 25%, shed nine pounds, lowered triglyceride fats 39%, reduced key markers for inflammation, and increased the body's production of nitric oxide, a very beneficial chemical that squelches plaque growth. Atherosclerosis, 191: 98, 2007.

Lower Blood Pressure To Normal, Medication-Free Levels

In a study of 268 men, 83% lowered their blood pressure to normal levels and left Pritikin free of all drugs for hypertension. Journal of Cardiac Rehabilitation, 3: 839, 1983. See also Circulation, 106: 2530, 2002.

In a meta-analysis of 1,117 hypertensives, nearly 60% normalized blood pressure and no longer required medications within three weeks of starting the Pritikin Program. Journal of Applied Physiology, 98: 3, 2005.

Enhance Effectiveness of Statin Therapy

Prior to attending Pritikin, 93 people had reduced their cholesterol about 20% on statins. After two weeks at Pritikin, they demonstrated an additional 19% decrease in cholesterol. American Journal of Cardiology, 79: 1112, 1997.

Control Diabetes and, for Many, Eliminate the Need for Drugs

A meta-analysis of 864 diabetics found that 74% on oral agents left Pritikin free of such medications; and 44% on insulin left insulin-free. Those who continued the Pritikin Program stayed off the medications. Journal of Applied Physiology,98: 3, 2005. See also Diabetes Care, 17: 1469, 1994.

Promote Healthy, Long-Term Weight Loss

Pritikin guests in need of weight loss shed on average 11 pounds within three weeks of starting the Pritikin Program. Archives of Internal Medicine, 151: 1389, 1991.

In two long-term studies, more than 85% of Pritikin graduates claimed a 50% or greater adherence to the Pritikin Program after 5 years, and the majority continued to lose weight after leaving the Center. Journal of Cardiac Rehabilitation, 3: 183, 1983; Diabetes Care, 6: 268, 1983.

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 dieters follow a diet, like Pritikin, that is low in fat and very high in fiber-rich carbohydrates like fruits and vegetables. The members lost, on average, 66 pounds and have kept it off for six years. Less than 1% follow a high-protein, high-fat diet. Journal of the American Dietetic Association, 98: 480, 1998.

Eliminate the Need For Coronary Bypass Surgery

A five-year follow-up of 64 participants who went to Pritikin instead of having bypass surgery found that 80% never needed surgery. Journal of Cardiac Rehabilitation, 3: 183, 1983.

Relieve Angina Pain

Among 64 heart patients taking drugs for angina (chest) pain, 62% left the Pritikin Longevity Center pain-free and drug-free. Journal of Cardiac Rehabilitation, 3: 183, 1983.

Reduce Key Risk Factors for Breast, Colon, and Prostate Cancer

Several studies have found that adopting the Pritikin Program reduced key risk factors for breast, colon, and prostate cancer. Journal of the National Cancer Institute, 86: 1419, 1994; Nutrition and Cancer, 31: 127,1998; Nutrition and Cancer, 38: 158, 2000; The Journal of Urology, 166: 1185, 2001.

Retard the Growth of Prostate Cancer Cells

Groundbreaking studies showed that the Pritikin Program retarded the growth of prostate cancer cells in in vitro laboratory testing, and even induced tumor cells to self-destruct. Prostate, 56: 201, 2003.

Retard the Growth of Breast Cancer Cells

Groundbreaking studies showed that the Pritikin Program retarded the growth of breast cancer cells in in vitro laboratory testing, and even induced tumor cells to self-destruct. Nutrition and Cancer, 2006.

Avoid Aggressive Treatment of Prostate Cancer

Patients with prostate cancer were able to avoid aggressive treatment, surgery, radiation, etc., by exercising regularly, increasing their fruit-and-vegetable intake, and reducing dietary fat to 10% of total calories. Journal of Urology, 174:1065, 2005
