Substrate partitioning & insulin control
One of 6 mechanistic pathways to 🔥 Lose fat · 14 options
Where a calorie goes matters as much as how many arrive. Chronically elevated insulin keeps hormone-sensitive lipase switched off — you cannot mobilise fat you are simultaneously storing. Improve glucose disposal and you change the destination of the same food.
This is the pathway with the clearest test. Fasting insulin above roughly 8 µIU/mL, triglyceride:HDL above 2, or raised uric acid all point at insulin resistance — and if that's your picture, this pathway outranks every other one on the page for you specifically.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
💉 Metformin
Complex-I inhibition raises the AMP:ATP ratio and activates AMPK; hepatic glucose output falls. Weight effect is modest and real. The most studied molecule on this entire page.
💉 Acarbose
Blocks α-glucosidase so complex carbohydrate is digested more slowly and further down the gut. Flattens the glucose curve and feeds the colonic microbiome — which is likely why it extends lifespan in mice.
💉 Canagliflozin
SGLT2 inhibition dumps roughly 200–300 kcal of glucose into the urine daily. Weight loss is real and mostly a direct calorie-excretion effect, with a genital-mycotic-infection cost.
💉 Amlexanox
Inhibits TBK1 and IKKε, two kinases that keep obese adipose tissue in a low-grade inflammatory, energy-conserving state. In mice it reverses insulin resistance and drives weight loss; a small human trial showed glucose improvement in responders only.
💉 GC-1
A thyroid-hormone-β-receptor-selective agonist (sobetirome). The design intent is hepatic lipid clearance and raised metabolic rate without the cardiac β1 effects of T3. Elegant mechanism, essentially no human fat-loss data.
💉 MK-677
Raises GH and IGF-1 around the clock. Increases lean mass reliably — but also appetite and fasting glucose, which makes it an actively poor fat-loss tool despite the body-composition marketing.
🧬 Myo-Inositol
Acts as a second messenger downstream of the insulin receptor. Strong trial support for insulin sensitivity in PCOS specifically, which is where the fat-loss extrapolation is best founded.
🧬 Chromium
Cofactor for insulin signalling. Supplementation helps meaningfully only where intake was low; the general fat-loss claim has not survived meta-analysis.
🧬 Ceylon Cinnamon
Improves fasting glucose modestly in trials. True Ceylon rather than cassia matters because cassia's coumarin load is hepatotoxic at habitual doses.
🧬 Apple Cider Vinegar
Acetic acid slows gastric emptying and blunts the post-prandial glucose spike. Small, replicated, and cheap.
🧬 Gymnema Sylvestre
Beyond taste-receptor blockade, gymnemic acids may reduce intestinal glucose absorption. Second mechanism, weaker evidence.
🧬 Magnesium
Cofactor for over 300 enzymes including several in the insulin-signalling cascade. Correcting a deficit improves insulin sensitivity measurably — this is repletion, not pharmacology.
🧬 Metabolic Health
A formulated blend aimed at the same pathway. Judge it on its components, not its name.
🧬 Taurine
Depleted by beta-agonists and involved in bile-acid conjugation and glucose handling. Supportive rather than driving.

14 options are mapped to this pathway in the Vault, including Metformin, Acarbose, Canagliflozin, Amlexanox. They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 7 carry clinical validation and 5 are mechanistic predictions.
This is the pathway with the clearest test. Fasting insulin above roughly 8 µIU/mL, triglyceride:HDL above 2, or raised uric acid all point at insulin resistance — and if that's your picture, this pathway outranks every other one on the page for you specifically. The markers worth checking are Fasting Insulin, HbA1c (Hemoglobin A1c), Lipid Panel (Cholesterol, HDL, LDL, Triglycerides), Uric Acid.
Unproven is not the same as ineffective. Of the 14 options on this pathway, 7 have clinical validation and 5 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
