ProLon Fasting Mimicking Diet

What Is the ProLon Fasting Mimicking Diet?

Most people think fasting means going without food entirely, uncomfortable, hard to sustain, and not something you can build into a regular routine. ProLon takes a different approach. Developed over 25 years of research, including work at USC's Longevity Institute, it's a plant-based, pre-portioned nutrition program that keeps your body in a fasting state while you're actually still eating. That matters, because fasting is when your body's real repair work happens: clearing out damaged cells (autophagy), burning fat while protecting muscle, and giving your metabolism a genuine reset.

I recommend ProLon to clients who want the metabolic benefits of a real fast without the headaches, exhaustion, and white-knuckling that come with going without food entirely.

Which ProLon Product Solves Your Problem?

Want the full 5-day reset? → Prolon 5-Day FMD

This is the core program and where almost everyone should start. Five pre-portioned daily boxes (soups, bars, olives, crackers, a supplement, and herbal tea) guide you through a complete fasting-mimicking cycle. It's the only nutrition program clinically shown to trigger autophagy in humans, and most people complete it feeling more energized and clear-headed than they expected, not depleted.

Want the easiest version to prepare? → Prolon 5-Day FMD, Next Gen

Same 5-day science, but built around ready-to-eat organic soups instead of mix-and-heat powders. If your hesitation about fasting is really about convenience, not commitment, this removes the prep step entirely.

New to fasting, or want to maintain results between cycles? → Prolon 1-Day Reset

A single-day version of the same technology. It's a low-commitment way to try fasting mimicking for the first time, or a maintenance tool to use between your full 5-day cycles.

Need something during your fasting window that won't break your fast? → Fasting Bar

Formulated specifically to satisfy hunger without pulling your body out of a fasting state or affecting ketone levels. Useful for ProLon cycles, and just as useful on any other day you're doing intermittent fasting and need something portable.

Want to extend your fast or need a meal replacement? → Fasting Shake

A plant-based shake designed to nourish your body while keeping it in a fasting state, longer than food alone typically allows. Good for extending a fasting window or replacing a meal without derailing your progress.

Focused on preserving muscle? → L-Protein

25g of complete plant-based protein, formulated specifically to support muscle synthesis without spiking the aging-related pathways that standard protein powders can trigger. This is what you reach for on your non-fasting days to protect the muscle mass ProLon's fasting technology already works to preserve.

Want ongoing longevity support between cycles? → ProLon L-Pill

A daily supplement built around four antioxidants and polyphenols, developed alongside USC's Longevity Institute. If you've completed a cycle and want to keep supporting cellular health day to day, this fills that gap.

Ready to commit to a full month? → Longevity Starter Pack

A bundle combining Fasting Bars, L-Protein, and a 1-Day Reset kit, built to support a month of intermittent fasting and everyday nourishment together, rather than buying each piece separately.

Want structured, 1-on-1 support with real lab tracking? → Metabolic Reset Program

This goes beyond a single kit. It pairs the ProLon fasting-mimicking technology with 1-on-1 coaching from a longevity-trained registered dietitian and quarterly bloodwork (CBC and metabolic panel) to track real progress. It's the right fit if you're managing a specific metabolic concern, blood pressure, cholesterol, blood sugar, and want accountability and measurable results along the way, not just a kit in a box.
