ProLon, the Fasting Mimicking Diet program, offers a novel approach to health and wellness, particularly in the context of preventing or reversing specific chronic diseases. This 5-day meal kit is designed to nourish the body while keeping it in a fasting state. The benefits of such a program include cellular renewal, support for metabolic health, and initiating weight loss. Fasting, especially when guided and structured as in ProLon, has shown promise in promoting health changes, including the cleanup and rejuvenation of cells​​​​.

The ProLon Fasting Mimicking Diet is unique in that it has undergone clinical trials at the University of Southern California and has been patented for its healthy-aging effects. This diet mimics fasting while providing food, a concept that aligns with intermittent fasting practices but with added structure and nutritional support. Over $36 million and 20 years of research by Dr. Longo at The Longevity Institute at the University of Southern California underpin the development of ProLon. This significant investment in research underscores the potential health benefits of this diet, particularly in the context of aging and chronic disease management​​​​.

For individuals interested in ProLon products, Truemed offers a financial advantage. ProLon products are approved for spending through Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA), which means that qualified customers can use these funds for purchasing ProLon. This can result in significant savings, potentially averaging 30%.
