Weight‑loss drugs can significantly amplify the results of balanced nutrition and exercise. However, long‑term success hinges on combining medication with lifestyle change—not relying on injections alone.
15% Weight loss
Semaglutide + Lifestyle Yields 15 % Weight Loss
In a 68‑week phase III trial (1,961 adults BMI ≥30), those treated with weekly semaglutide plus diet and exercise lost on average 14.9 % of body weight, versus 2.4 % with placebo alone.

Exercise + GLP-1
Exercise + GLP‑1 Reduces Inflammation & Metabolic Risk
One trial found combining liraglutide with ≥150 min/week of aerobic exercise resulted in larger reductions in abdominal fat, metabolic syndrome severity, and CRP inflammation markers versus either treatment alone.

Muscle Retention
Muscle Retention with Resistance Training
Doctors emphasise the need for adequate protein intake and resistance training (60–90 mins/week plus aerobic exercise) to prevent up to 25 % muscle loss during rapid weight drop.

Real-World Outcomes Match Clinical Trials
A cohort study in clinical settings found 5.9 % weight loss at 3 months and 10.9 % at 6 months with semaglutide—comparable to trial data—when paired with lifestyle changes.

Exercise + Maintenance
Exercise Improves Long-Term Maintenance
After stopping treatment, weight regain was 6 kg larger for people stopping GLP-1 medication alone than for those who had added supervised exercise, underscoring that exercise aids sustainable results.

Other Benefits
Metabolic & Cardiovascular Benefits
Beyond weight loss, GLP‑1 agonists may reduce inflammation, improve heart outcomes, and benefit metabolic health markers—but only when paired with healthy eating and regular fitness.

4-6KG Weight Loss
Liraglutide Shows Reliable Modest Loss
Across multiple RCTs, daily liraglutide (with recommended diet and physical activity) consistently led to 4–6 kg weight loss, with significantly more people achieving ≥5 % or ≥10 % loss versus placebo.

Lifelong Changes, Not Shortcuts
Major clinical trials have always paired GLP‑1 treatments with structured nutrition and fitness regimens; stopping medication alone often leads to weight regain. Long-term support is key.
