    The post hoc analysis by Horn et al highlights significant weight regain and metabolic benefit reversal after tirzepatide withdrawal.

  • 2

    Weight regain is likely driven by physiological counter-regulation, including decreased leptin and increased ghrelin levels.

  • 3

    The study's 36-week lead-in period may be insufficient for establishing durable lifestyle habits and behavioral adherence.

  • 4

    Absence of body composition data limits understanding of the metabolic cost of weight regain, particularly fat versus lean mass.

  • 5

    Future research should focus on hormonal profiling, behavioral support during treatment cessation, and body composition analysis.
