The Science

How metabolic therapy actually works.

Mitochondria run your biology. When they work, you're fuel-flexible. When they don't, the body defaults to glucose — and inflammation, insulin resistance, and chronic disease follow. Therapeutic ketosis is the lever. The GKI is the readout. Here's the biology, the measurement, and the published evidence behind our coaching protocol.

Mitochondria

The engines inside every cell.

Healthy mitochondria are fuel-flexible — they can run on glucose or on fat-derived ketones. Decades of glucose-default eating breaks that flexibility. The cell loses quality control, inflammation rises, and the downstream consequences show up as metabolic syndrome, accelerated aging, and elevated cancer risk.

The metabolic-therapy thesis: restore fuel flexibility and you change the inputs to all of it.

In ketosis

When the body burns ketones, three things change.

Each one has decades of literature behind it. None of it is a hack — it's how your biology was built to operate when carbs are low.

Cellular renewal turns on

Low insulin and elevated ketones trigger autophagy — the body's built-in process for clearing damaged cellular components. It's the lever every "longevity" intervention tries to pull. Ketosis pulls it the way nature designed.

Inflammation comes down

Stable blood sugar means stable insulin. Stable insulin means less chronic inflammatory signaling and less oxidative stress on the cells you want to keep healthy.

Energy gets steady

Glucose spikes and crashes. Ketones don't. When the body learns to run on fat between meals, the 2pm crash and the 4pm cravings stop being a daily event.

What's the GKI?

Glucose-Ketone Index. One number that captures where you are between glucose-default and therapeutic ketosis. A CGM only tells you about glucose; the GKI tells you whether your body has actually crossed over into burning fat. We coach against this readout daily.

Clinical evidence

Three trials that shaped the protocol.

Therapeutic ketosis in cancer is an active research field, not settled science. These are the early-phase studies we read closest. We don't claim MyMetabolism reproduces these results.

Phase 2 · pancreatic cancer
+3.5 mo

Median overall survival vs. control

Ketogenic diet alongside chemo — well-tolerated, early signal

Randomized Phase 2 trial in metastatic pancreatic cancer. 94% of patients reached ketosis. No added toxicity. Early signals favored the ketogenic arm in progression-free survival (8.5 vs. 6.2 mo) and overall survival (13.7 vs. 10.2 mo). Larger trials needed.

Phase 1 · glioblastoma
Safe & feasible

Alongside standard-of-care

Ketogenic diet in newly-diagnosed GBM — ready for larger trials

2025 Phase 1 trial established that a medically-supervised ketogenic diet is feasible and tolerated alongside standard-of-care for newly-diagnosed glioblastoma patients. Early signal supporting further investigation.

Phase 2 · type 2 diabetes
−55%

Insulin resistance, one year · 30 lb avg. weight loss

Nutritional ketosis program — the mature evidence base

Adults on a coached nutritional-ketosis program for one year cut insulin resistance in half and lost 30 lbs on average — without medication. The closest published analogue to what we coach.

This research is preliminary. MyMetabolism is not a clinical trial and does not provide medical treatment. We coach people who have chosen to pursue metabolic therapy in coordination with their medical team.
