The Pritikin Diet emphasizes unprocessed or lightly processed foods. It focuses on what are called “nature foods” such as vegetables, fruits, whole grains, legumes, starchy vegetables, seafood, and lean meat. This plan is more than a diet, as it also recommends aerobic exercise and weight training several times a week. The Pritikin Diet was designed by Nathan Pritikin, first, for his own early-diagnosed heart disease and, later, to have a positive effect on hypertension, heart disease, obesity, and Type 2 diabetes for anyone interested in improving his health. A secondary result of following the plan, of course, is significant weight loss. The regime became known as The Pritikin Program for Diet and Exercise.
