Taking a weight-loss medication, such as Wegovy (semaglutide), is a promising new way to lose weight. However, the scale doesn’t always change as quickly as you might expect.

Weight loss with Wegovy is usually a long-term process. Studies show that people continue to lose weight for about 65 weeks before their weight plateaus.

This article explains why your weight loss may have slowed and how to get back on track.

You start Wegovy on a low dose of 0.25 mg and increase the dose every 4 weeks. This process, called titration, helps your body get used to the medication and reduces side effects, such as nausea.

The standard maintenance dose for weight loss is 2.4 mg per week, and studies show that people reaching this dose lost more weight than those who stayed on lower doses. So if you’re on a low dose, you may just need more time to reach an effective dose for you.

Wegovy is designed to be used alongside a reduced-calorie diet and more physical activity. If you haven’t changed your eating habits or you’re consuming high-calorie snacks, you might be taking in more calories than is necessary for weight loss.

Every person’s body is unique, and people respond to medications differently. Some people are lower responders, meaning their bodies don’t react as strongly to the hormone signals from drugs like Wegovy. Several factors can influence this:

When you lose weight, your body loses a combination of fat and lean muscle mass, which includes muscle, bone, and fluids. Research shows that 15% to 60% of the weight lost with Wegovy can come from lean mass.

This matters because muscle is like an engine that burns calories even when you’re resting. For every kilogram (about 2.2 pounds) of muscle you lose, your body burns about 13 fewer calories every day. If you lose too much muscle, your metabolism slows down, which can make it harder to keep losing weight or even maintain your current weight.

It’s common to experience a weight loss plateau, which is a period of several weeks when your weight doesn’t change. This happens because of metabolic adaptation.

As you lose weight, your body thinks it’s starving and tries to become more efficient at saving energy. It lowers your resting metabolic rate and increases signals that make you feel hungry, to help you get back to your previous weight. This is a normal survival mechanism, but it can be frustrating when you’re trying to reach a goal.

Wegovy is designed to be taken once per week on the same day. If you’re skipping doses or taking them at irregular times, your body won’t maintain the steady level of semaglutide it needs to suppress appetite.

“Variety may be one key to overcoming a weight loss plateau. Reevaluating your diet and changing up your workout routine may help you break through the plateau and support your weight loss goals.”
