GLP-1 Side Effects

Is This You?

You're on (or considering) semaglutide or tirzepatide, and you're worried about the side effects — or already dealing with them.

What the Research Shows

GLP-1 medications work by mimicking the hormone that signals fullness and slows digestion. That mechanism is also what causes the common side effects: nausea, delayed stomach emptying, and reduced appetite.

The bigger, less-talked-about risk is muscle loss. Rapid weight loss — especially with appetite suppression that reduces protein intake — can burn muscle along with fat. Muscle loss lowers your metabolic rate and raises the odds of regain when you stop the medication.

How to Manage It

Side effects are dose-related and usually manageable: slow dose titration, smaller more frequent meals, and avoiding high-fat or fried foods near injection days. Muscle preservation is non-negotiable: 1.6–2.4 g/kg of protein daily, resistance training 2-3 times per week (which keeps the mTOR muscle-building pathway sensitive for 48 hours), and adequate sleep.

A supervised program manages both the side effects and the muscle-loss risk — so you keep the benefits and protect your metabolism. Call (561) 903-1899.
