The key facts about weight loss on Wegovy tabletsAround 13.6% on average
Across studies of about a year, people lost an average of 13.6% of their body weight, with some losing up to 20%.
Gradual, not overnight
Weight comes off steadily. Most people achieve a significant proportion of their loss by around six months, continuing through year one.
Results vary person to person
Your starting weight, diet, activity, consistency and how your body responds all shape how much you lose.
How much weight can you lose with Wegovy tablets?
Combined with a reduced-calorie diet and more physical activity, studies show people can lose up to 20% of their starting body weight. Across trials lasting around a year, the average loss was 13.6%, with many people achieving 15% or more.
The number on the scales is only part of the story. Losing weight can ease the strain on your heart, joints and muscles — making everyday activities feel easier — and can help lower your risk of weight-related conditions such as type 2 diabetes and high blood pressure.
How quickly do Wegovy tablets work?
Wegovy tablets begin working from your very first dose, but that doesn't mean you'll see dramatic changes overnight. During the first few weeks, many people notice that they feel fuller sooner, think about food less often and find it easier to control their portion sizes. As your dose is gradually increased each month, these effects usually become more noticeable, making it easier to stick to healthier eating habits.
Weight loss tends to happen gradually rather than all at once. Many people begin to lose weight within the first month or two, with steady progress continuing as treatment goes on. By around six months, most people have already achieved a significant proportion of their overall weight loss, with improvements continuing throughout the first year when Wegovy tablets are combined with a reduced-calorie diet and regular physical activity.

What factors affect your weight loss?
Wegovy tablets help reduce your appetite, but they work best alongside healthy lifestyle changes — which is why everyone's journey is different. Small, sustainable changes tend to make the biggest difference over the long term. And remember, weight loss isn't always linear: some weeks you'll lose more than others, and occasional plateaus are completely normal.
