AMP-activated protein kinase (AMPK) is a key cellular energy sensor and regulator of metabolism. Scientific evidence supports its role in fat metabolism, particularly in the context of metabolic disorders such as obesity and type 2 diabetes. When cellular energy is low (characterized by a high AMP/ATP ratio), AMPK is activated. Once activated, AMPK stimulates pathways that generate ATP, such as fatty acid oxidation, while inhibiting energy-consuming processes like fatty acid synthesis and cholesterol synthesis.

Numerous preclinical and clinical studies have demonstrated that pharmacological activation of AMPK (using compounds like AICAR, metformin, or natural products such as berberine) can enhance fat metabolism and improve lipid profiles. For instance, metformin, a first-line drug for type 2 diabetes, exerts much of its glucose- and lipid-lowering effects through AMPK activation. In animal models, AMPK activation reduces hepatic fat accumulation and increases mitochondrial fatty acid oxidation.

However, while the mechanistic evidence is robust and there are supportive clinical findings (especially with indirect AMPK activators), direct pharmacological activation of AMPK specifically for treating "poor fat metabolism" in otherwise healthy individuals is still under investigation. The majority of current evidence is strongest in populations with metabolic dysregulation. Overall, the scientific rationale for targeting AMPK to support or treat impaired fat metabolism is well established, though further research is needed to optimize therapeutic strategies and assess long-term safety in broader populations.
