The PPARδ agonist GW501516 increases fatty acid oxidation in human skeletal muscle through a mechanism that requires both PPARδ expression and functional AMPK.

This study shows that maximizing fat oxidation in muscle cells requires both PPARδ and AMPK to be active. While GW501516 is not a consumer product, this suggests that natural methods activating both pathways (like high-intensity exercise which activates AMPK and can upregulate PPARδ over time) are synergistic for lipid metabolism.

Furthermore, we have shown that the subsequent increase in fatty acid oxidation induced by GW501516 is dependent on both PPARδ and AMPK.
