Decades of metabolic research show that insulin — not calories — is the master switch for fat storage. Control your carbs, practice intermittent fasting, lower your insulin — and your body switches to its natural fat-burning state. MetaFy is built on this science.
Our approach prioritizes intermittent fasting and controlling carbohydrate intake to regulate insulin levels. When insulin drops, your body enters a fat-burning metabolic state — the key to lasting body recomposition.
Our model analyzes your body composition and predicts what you'll look like after switching to a low-carb, insulin-controlled lifestyle — showing your lean future self based on real metabolic fat adaptation science.
MetaFy calculates exactly how many weeks of fasting and carb control it takes to reach your goal based on your metabolic profile. Real science, real deadlines — not vague promises.
Just take a picture of what you want to eat. Our AI instantly tells you whether it's fine for your insulin and metabolic goals — or if it will spike your insulin and kick you out of fat burning.
MetaFy's approach is grounded in decades of peer-reviewed research on insulin resistance, intermittent fasting protocols, and the metabolic switch from glucose burning to fat oxidation.
🎓
Brigham Young University · Metabolic Scientist
Author of Why We Get Sick. His research proves that insulin resistance — not overeating — is the root cause of obesity, type 2 diabetes, and chronic metabolic disease. MetaFy is built on the principle that controlling insulin is the key to fat loss.
🎓
Nephrologist · Fasting Protocol Pioneer
Author of The Obesity Code and The Complete Guide to Fasting. Dr. Fung demonstrated that intermittent fasting is one of the most powerful tools to lower insulin levels, reverse insulin resistance, and trigger the body's natural fat-burning metabolic state.
🎓
UCSF Neuroendocrinologist
Author of Fat Chance and Metabolical. His research on how sugar and processed carbs drive chronic insulin elevation — leading to metabolic syndrome and fat storage — forms the scientific basis for MetaFy's carb-control-first approach.
🎓
Longevity Physician · Metabolic Health Expert
Author of Outlive. Dr. Attia emphasizes metabolic flexibility — the ability to switch between burning glucose and burning fat. MetaFy helps you achieve this switch through fasting, carb control, and real-time metabolic tracking.
🎓
UC Davis · Nutritional Biochemist
A pioneer in low-carbohydrate and ketogenic research. Dr. Phinney's work on fat adaptation and nutritional ketosis shows that when carbs are restricted and insulin drops, the body becomes a highly efficient fat-burning machine — the metabolic state MetaFy helps you reach.

The Science Behind MetaFy
When you fast and control carbs, insulin drops. Low insulin signals your body to release stored fat for energy — flipping the metabolic switch from glucose dependence to fat oxidation. This is called metabolic flexibility, and it's the core principle powering every feature in MetaFy.
