Chronic activation of AMPK using the direct activator A-769662 promotes white adipose tissue browning, increases energy expenditure, and protects against diet-induced obesity and metabolic dysfunction in high-fat diet-fed mice.
This study suggests that directly activating the AMPK enzyme in fat cells using a specific compound (A-769662) can help burn fat and prevent obesity in mice. While this is not a human supplement, it supports the idea that boosting cellular energy sensors (like AMPK) through exercise or diet might mimic these effects.

In contrast, we found that in HFD-fed obese mouse model, chronic AMPK activation by A-769662 protected against obesity and related metabolic dysfunction. A-769662 alleviated HFD-induced glucose intolerance and reduced body weight gain and WAT expansion. Notably, A-769662 increased energy expenditure and cold tolerance in HFD-fed mice. A-769662 treatment also induced the browning process in the inguinal fat depot of HFD-fed mice.
Why this rating
High-quality mechanistic data in mice, but lacks human clinical trials.
