Why do people plateau on semaglutide?

A weight-loss plateau on semaglutide happens because your body adapts to a lower weight: metabolism slows, appetite can partially return, and the same dose has less relative effect. Plateaus are a normal phase of treatment and can usually be addressed with a dose review, higher protein intake, resistance activity, and physician-guided adjustments.

The biology of a plateau

When you lose weight, your body burns fewer calories at rest (adaptive thermogenesis) and hunger hormones can rebound. This narrows the gap between calories in and calories out until weight stabilizes — often 3 to 6 months into treatment.

How to break through

Confirm you are on the right dose with your physician — many plateaus resolve with a planned titration step.

Prioritize protein (roughly 0.7–1 g per pound of goal body weight for many adults) and resistance activity to protect metabolism-supporting muscle.

Track intake honestly for two weeks; appetite suppression can ease over time, allowing portions to creep up.

Discuss whether switching to a dual-agonist (tirzepatide) is appropriate for your goals.
