The Pritikin Diet — Heart Program Evidence, Core Rules, and A Sample Day
Links:
Summary
The Pritikin Diet centers meals on vegetables, fruits, intact whole grains, beans and lentils, and modest portions of nonfat dairy or soy. Added oils are minimized. The plan sits inside a broader lifestyle program that includes daily movement, stress management, and education in clinical settings.
Core Principles of the Pritikin Diet
Build plates from fiber-rich plants and keep added fats very low. Choose beans or lentils for protein, intact grains for steady energy, and lots of vegetables and fruit for micronutrients and phytochemicals. If dairy is used, select nonfat options or fortified soy. The program is usually delivered as part of intensive cardiac rehabilitation with exercise and behavior change support recognized by Medicare.

Health and Practical Considerations
Peer-reviewed and program evaluations show improvements in weight, lipids, blood pressure, and other cardiometabolic risk factors in Pritikin intensive cardiac rehabilitation participants. Medicare’s National Coverage Determination lists the Pritikin Program as an approved Intensive Cardiac Rehabilitation model based on published evidence. Contemporary outpatient and worksite studies report feasibility and short-term risk factor gains when the Pritikin approach is delivered in real-world settings. As with any pattern, outcomes depend on adherence and overall lifestyle support.
Practical tips
• Make vegetables and legumes the base of most meals and keep added oils low.
• Use intact grains like oats, barley, brown rice, and farro instead of refined grains.
• Choose nonfat dairy or fortified soy if included.
• Plan for vitamin B12 and iodine if animal products are minimal, and watch calcium and iron.
