Dr. Jonathan Schoeff is a board-certified surgeon and longevity medicine physician, and the founder of The Longevity Lab in Denver. His approach centers on cellular metabolism as the driver of health fixing the underlying machinery instead of treating symptoms one at a time.

What impressed me most was the honesty. There are no miracle claims or fear-based messages—just straightforward explanations backed by science. I finally feel like I understand why certain habits matter and how to prioritize them.

I appreciate that the recommendations aren't about doing more—they're about doing the right things. The emphasis on fixing the root causes instead of chasing symptoms completely changed the way I think about my health.

This tool provides general educational information based on a therapeutic fasting protocol and is not a substitute for professional medical advice, diagnosis, or treatment. Always consult your own physician before beginning any fasting program, especially if you have an existing health condition or take medication. If you experience a medical emergency, seek urgent care immediately.
The Problem
One coach, trained on the entire protocol not a summary of it.
Data Coach
Reads your glucose & ketones
Tell it your numbers and it applies the Dr. Boz Ratio to tell you whether to continue or break the fast — no guesswork.
Meal Plan Builder
Builds your eating days
Protein, carbs, and fat targets calculated from your bodyweight and training load, on eating days and refeed days alike.
Workout Plan Builder
Places your training correctly
Slots the glycogen depletion session before your fast and keeps heavy lifting off the fasting and refeed days.
