7 Reasons Your GLP-1 Weight Loss Has Stalled (And How to Fix It)

Experiencing rapid weight loss in the first few months of starting a GLP-1 medication like Ozempic, Wegovy, or Mounjaro is incredibly common. But what happens when the scale suddenly stops moving? Hitting a weight loss plateau is frustrating, but it's also a perfectly normal biological response. Your body is designed to adapt, and understanding why your progress has stalled is the first step to getting things moving again.

Here are the 7 most common reasons for a GLP-1 weight loss plateau and how to address them.

1. Metabolic Adaptation

As you lose weight, a smaller body requires fewer calories to maintain its weight. If you are eating the same amount of food at month six as you were at month one, you may no longer be in a calorie deficit. Your metabolism naturally slows down to conserve energy as body mass decreases—a phenomenon known as adaptive thermogenesis¹.

2. Inadequate Dosage

GLP-1 medications require titration (gradually increasing the dose) to reach therapeutic levels. If you've been on a starting or intermediate dose for a long time, your body may have adapted to the appetite-suppressing effects. Always consult your doctor to see if a dosage adjustment is appropriate.

3. Muscle Loss

Losing weight quickly often means losing muscle alongside fat. Muscle tissue contributes to resting metabolic rate²; it burns calories even when you're resting. If you've lost a significant amount of muscle, your resting metabolic rate has dropped, making it harder to continue losing weight.

4. Unnoticed Calorie Creep

Appetite suppression can sometimes waver, especially toward the end of the week before your next injection. You might be unknowingly snacking more, using larger portions of healthy fats (like olive oil or nuts), or drinking high-calorie beverages that sneakily erase your calorie deficit.

5. Insufficient Protein Intake

Protein is critical not only for maintaining the muscle mass mentioned above but also because it has a higher thermic effect of food (TEF)—your body burns more energy digesting protein than fats or carbs³. Furthermore, a low-protein diet leaves you feeling less satiated, leading to more grazing.

6. The Stress and Sleep Connection

High levels of cortisol (the stress hormone) are associated with increased abdominal fat accumulation⁴. Poor sleep quality exacerbates this issue by disrupting your hunger hormones (ghrelin and leptin)⁵, which can counteract the appetite-suppressing effects of GLP-1 medication.

7. Natural Biological Set Points

Some research suggests your body may fight to maintain a certain weight range—often called the "set point" theory⁶. After significant weight loss, your body may resist further loss as a protective mechanism. A plateau isn't always a failure; sometimes it's a necessary stabilization period before the next phase of loss.
