The Pritikin Program for Diet and Exercise was created by Nathan Pritikin. The book based on the diet became a best-seller on the New York Times Bestseller list and was entitled "The Pritikin Program for Diet and Exercise", and was co-authored by Patrick M. McGrady.
Pritikin was regarded as one of the major diet gurus of the early 1980's, a class which also included Dr. Robert Atkins, Gary Null, and Dr. Tarnower of the Scarsdale Diet.
The Pritikin Program was often described by Nathan Pritikin, its creator, as “mankind’s original meal plan.” That’s because the focus of the Pritikin diet is unprocessed or minimally processed straight-from-nature foods like fruits, vegetables, legumes (such as black beans and pinto beans), whole grains such as brown rice, starchy vegetables like potatoes and yams, lean meat, and seafood.
The Pritikin Program also emphasizes another key characteristic of humankind up until the last century: plenty of daily exercise, including at least 30 minutes of aerobic exercise like brisk walking, weight training two to three times weekly, and stretching, optimally every day.
Research supporting the Pritikin Program
In several studies published since 1975, scientists at UCLA and other research institutions have found the Pritikin Program effective in preventing the major diseases that afflict modern society, such as heart disease, type 2 diabetes, hypertension, and obesity. The Pritikin Program has been documented to improve cholesterol profiles better than cholesterol-lowering drugs like statins, and has also been found to lower blood sugars, normalize blood pressure, and shed excess weight.
A meta-analysis of 864 type 2 diabetics found that 74% on oral medications left the Pritikin Longevity Center within three weeks free of these drugs, their blood sugars in normal ranges, and 44% on insulin left insulin-free.
