In this YouTube presentation, Ashley F explains the role of the mitochondrial-derived peptide MOTS‑c as a metabolic distress signal released during exercise, fasting, and cold exposure. She outlines how MOTS‑c activates the AMPK pathway in skeletal muscle, leading to improved insulin sensitivity, enhanced fat oxidation, and greater endurance. The speaker highlights key mouse studies: (1) mice on a high‑fat diet that received MOTS‑c never developed obesity or insulin resistance, and (2) obese, insulin‑resistant mice given MOTS‑c after disease onset showed reversal of both conditions. The narrative suggests that supplementing with exogenous MOTS‑c could replicate these benefits in humans, positioning the peptide as a promising therapeutic target for metabolic health.

If your mitochondria are sending out MOTS-c as a metabolic distress signal during exercise and fasting and cold plunging, and if this thing is improving insulin sensitivity and fat burning, mitochondrial function, and endurance, well then the next question could be, well, what happens if you give yourself the peptide, more of it? Well, guess what? We have quite a bit of research on this stuff, and here's what I've read. The discovery research of MOTS-c in 2015 demonstrated that MOTS-c targets Skeletal muscle, and it activates that AMPK pathway. And I'm not kidding. In this study, the researchers took a group of mice, fed them a high-fat diet that made them obese and insulin resistant. Then they gave another group of mice the same diet and gave them MOTS-c, and those mice never got fat or insulin resistant. They also took mice who did get fat on that same diet and then gave them MOTS-c and reversed the obesity and insulin resistance after it had already developed. So you've got mice eating the same diet and different outcomes.
