The effect of Tirzepatide on Fat-Free Mass (FFM) is inconclusive and uncertain, with evidence showing significant FFM loss that may be greater than or comparable to other anti-obesity drugs depending on the dose and study.

Current research does not provide a clear answer on whether Tirzepatide preserves muscle mass better than other weight loss strategies. Some studies indicate significant muscle loss occurs alongside fat loss, while others suggest it might be less severe than with other drugs. More research is needed to determine if specific dosing protects lean mass.
