Stored fat fights against the body's attempts to lose weight

A study published in Nature Communication found that a protein called sLR11 acts to inhibit thermogenesis, or heat production, in fat cells, making it harder for the body to burn excess fat. This protein is produced by fat cells and increases with total fat mass, suggesting its role in storing energy over long periods.
