Animal Study Uncovers Distinct Metabolic Effects of Tirzepatide Versus Semaglutide
New preclinical research presented at the 2025 European Congress on Obesity (ECO) in Malaga, Spain, reveals that the anti-obesity drugs tirzepatide and semaglutide produce markedly different short-term metabolic responses in mice. While tirzepatide transiently increases energy expenditure, semaglutide initially suppresses it. Both agents, however, converge on enhanced fat oxidation and appetite suppression, with the most pronounced metabolic shifts occurring during active treatment and rapidly waning once dosing ceases.
