Do you need to diet & exercise on wegovy

Content

Wegovy (semaglutide) is a glucagon-like peptide-1 (GLP-1) receptor agonist medication prescribed for chronic weight management in adults with obesity or overweight and weight-related comorbidities.

While Wegovy a weight loss injection offers a powerful tool to help you reach your weight loss goals, a common question arises: can it work alone, or are diet and exercise still necessary for successful weight loss?

Science Says: Wegovy + Diet + Exercise = Success

Clinical trials consistently demonstrate that Wegovy, in conjunction with a reduced-calorie diet and increased physical activity, leads to superior weight loss compared to Wegovy alone. In a key study published in the New England Journal of Medicine, Wegovy users on a low-calorie diet achieved an average weight loss of 14.8% compared to 2.4% in the placebo group.

Similarly, another trial showed a dose-dependent increase in weight loss with Wegovy, with participants receiving the highest dosage alongside a calorie-restricted diet losing an average of 17.4% of their body weight.

Why Diet Matters

It’s mechanism of action revolves around GLP-1 receptors, which influences appetite, but creating a calorie deficit remains essential. A reduced-calorie diet restricts the calories your body takes in, forcing it to burn stored fat for energy. 

This can be achieved through:

  • Portion control: Smaller meals and snacks help manage calorie intake.
  • Mindful eating: Paying attention to hunger and fullness cues prevents overeating.
  • Food choices: Prioritizing low-calorie, nutrient-dense options like fruits, vegetables, and whole grains keeps you feeling full without exceeding calorie limits.

The Power of Exercise

Exercise compliments Wegovy by:

  • Burning calories: Physical activity directly increases calorie expenditure.
  • Building muscle: Muscle tissue burns more calories at rest, boosting metabolism.
  • Improving insulin sensitivity: Exercise enhances the body’s ability to use insulin, aiding blood sugar control.

Wegovy Diet and Exercise

Studies show combining Wegovy with a reduced-calorie diet and exercise leads to superior weight loss compared to Wegovy alone. Wegovy works by targeting GLP-1 receptors, which influence appetite, satiety, and blood sugar. While it suppresses appetite, a calorie deficit from diet is still crucial. Exercise further amplifies this by burning calories and promoting muscle growth, which increases metabolism.

Long-Term Success

It significantly aids weight loss, but sustained results depend on adopting healthy diet and exercise habits. Studies suggest lifestyle modifications in conjunction with GLP-1 receptor agonists like Wegovy are more successful for long-term weight management than medication alone.

The Takeaway

Wegovy is a powerful weight-loss medication, but it is not a standalone solution.  For optimal and sustainable weight loss, it should be used in combination with a reduced-calorie diet and exercise. Consult with your healthcare professional to create a personalised plan incorporating Wegovy, dietary adjustments, and an exercise program suitable for your needs and health status.
