Tirzepatide: Preserving Muscle Quality in Type 2 Diabetes
đ„ Big weight loss, small muscle loss đ„
In the 52-week SURPASS-3 MRI substudy, adults with T2D on tirzepatide lost ~10% of body weightâbut thigh muscle volume only fell by ~0.64 L (~6%), matching what youâd expect from ânormalâ weight loss alone, not an accelerated muscle drain.
đȘ Muscle quality actually improved đȘ
The magic? Muscle fat infiltration dropped by ~0.36 ppâgreater than population-based estimates (â+0.06 pp). In other words, patients' muscles got leaner and healthier.
đïžââïž Put a pinch on protein, but⊠đ„
Yes, higher protein intake can help preserve lean mass during energy deficits, but letâs be real: resistance training is the undisputed
#1 driver to stave off muscle loss. Protein is a very distant
#2 in its impact.
đ Whatâs next?
Imagine pairing tirzepatide with a structured RT programâcould we boost muscle retention and strength (what about bone) even more? Weâre still waiting on those data, but the hypot...
