When mice have extra TFAM protein in their muscles and eat a high-fat diet, their muscles get better at burning fat, make less of a harmful fat-related chemical that causes insulin problems, and still take in sugar well—helping them stay healthy despite the bad diet.

TFAM Enhances Fat Oxidation and Attenuates High-Fat Diet–Induced Insulin Resistance in Skeletal Muscle

Randomized Controlled Trial

Animal

2019 Aug

The study found that boosting a specific protein (TFAM) in mouse muscles helped them burn fat better and reduced harmful fats linked to insulin resistance, while also helping muscles take in more sugar — exactly what the claim says.

Similar Assertions

Extra TFAM in mouse muscles helps their mitochondria produce less harmful free radicals and makes more natural antioxidant defenses, which keeps the muscle cells from getting damaged and helps them respond better to insulin.

Extra TFAM in mouse muscles makes their mitochondria slightly leaky (mild uncoupling), which helps them stay stable and not collapse when flooded with fat—this keeps them from making too many harmful free radicals.

Extra TFAM in mouse muscles turns on a cellular energy sensor (AMPK), which then activates genes (PGC-1α, PPARβ) that help the muscle take in more sugar and burn fat better—improving how it responds to insulin.
