The GLP-1 Plateau: Why Weight Loss Stalls Around Month 6 (and How to Break It)

As you lose weight, your basal metabolic rate drops by roughly 15–25 calories per pound lost. Lose 40 lb and your daily energy needs are 600–1000 calories lower than they were at the start. The medication's appetite-suppression effect doesn't change, but your math does — you start matching intake to your new, smaller body.

On top of that, hormonal counter-regulation kicks in: leptin drops, ghrelin rises slightly, and thyroid output edges down. The body fights to defend its new lower weight.

Make sure you're actually at the maintenance dose. Many users stall on the second-to-top dose because their clinician hesitated to escalate. If you're tolerating 2.0 mg semaglutide or 10 mg tirzepatide without issues, ask about moving to 2.4 mg or 15 mg.

If you've lost muscle, your BMR is lower than it should be. Pull up your protein intake to 1 g per pound of goal weight and add a third lifting day if you've been doing two.

GLP-1 users often unconsciously move less. Add 3,000 steps to your daily baseline (a 30-minute walk) — that's roughly 150 extra calories burned per day with no appetite cost.

If you've done all of the above and are still stuck after 6 weeks, that may be your body's natural set point on this medication. Hold the line for another 8–12 weeks — many users see a delayed second drop. Stopping the medication almost always means regain.
