Since 1975, more than 75,000 guests have experienced the life-changing benefits of the Pritikin Longevity Center® & Spa. Nearly 10 million have read the 10 best-selling books on the Pritikin Program. Most importantly, no other diet-and-exercise program has been more highly praised by the scientific community. More than 90 studies in top medical journals have found that people who adopt the Pritikin Program achieve dramatic results in just a few weeks, with more benefits long-term. The Pritikin Program has been proven to:

Cholesterol: 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. See also Circulation, 106:2530, 2002.

Triglycerides: These 4,587 Pritikin guests also reduced triglycerides on average 33%. New England Journal of Medicine, 323:1142 ,1990; Archives of Internal Medicine, 151: 1389, 1991.

C-Reactive Protein: 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.

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

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

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.

In research on 652 diabetics, 70% on oral agents left Pritikin free of such medications; 39% on insulin left insulin-free. Participants who continued the Pritikin Program stayed off the medications. Diabetes Care, 17: 1469, 1994.

Pritikin guests in need of weight loss lose 12 pounds and more within three weeks of starting Pritikin. Archives of Internal Medicine, 151: 1389, 1991.

In 2003, the world's top experts in weight control and health published a 116-page World Health Organization report announcing that the optimal diet for losing weight and preventing disease is a diet, like the Pritikin Program, that is low in fat and high in natural, fiber-rich carbohydrates. The most comprehensive study of long-term weight loss ever conducted found that the vast majority of its nearly 4,500 successful dieters follow a diet that is low in fat and 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.

A five-year follow-up of 64 participants who went to Pritikin instead of having bypass surgery found that 80% never needed surgery. Of those taking drugs for angina (chest) pain, 62% left the Center pain-free and drug-free. Journal of Cardiac Rehabilitation, 3: 183, 1983.

High insulin levels, high blood pressure, high triglycerides, and obesity commonly aggregate in the same individual and greatly increase the risk for coronary disease. The Pritikin Program controlled this syndrome in just three weeks in a majority of 72 people studied. Fasting insulin was reduced by 30-40%. American Journal of Cardiology, 69: 440, 1992.

Several studies have found that adopting the Pritikin Program reduced suspected 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.

The latest research provides groundbreaking data showing that the Pritikin Program induced prostate cancer cells to die. Prostate, 56:201, 2003.

The customized smoking cessation program at Pritikin has helped many guests quit smoking for good. Plus, their new Pritikin lifestyles helped ensure that they did not gain weight while quitting. Many, in fact, lost weight.
