A recent study reveals that patients who come off blockbuster weight-loss injections like Wegovy and Mounjaro can put back on reduced body mass much more quickly than those who end conventional lifestyle programs.
Published data in a prominent health publication shows that while overweight individuals frequently drop substantial amounts of their total mass while undergoing treatment, the mass returns at an average rate of nearly a kilo each month after stopping.
"Individuals buying these drugs should be informed of the danger of rapid rebound weight gain when the medication concludes," warns expert Dr. Susan Jebb.
That rate of regain suggests a return to pre-treatment weight within about a year and a half.
Comparing Therapies
The analysis, which examined 37 of studies involving thousands of patients, contrasted the effects of the injectable medications with older methods.
Scientists note that people who lose weight through diet and exercise usually experience a less rapid weight regain—around 100 grams monthly—post-intervention.
The Reason for the Quick Rebound
Nutrition scientists believe the way of the injections accounts for the accelerated weight return.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone concentrations far above than normal may cause the body to produce less of its endogenous hormone, and could reduce responsiveness to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' means appetite is no longer kept in check, making overeating far more likely."
A Chronic Issue?
Health authorities recommend the injections for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals contend that, considering the significant potential of relapse, the treatment is often life-long.
This perspective is reinforced by drug manufacturers, who state that the results "emphasize the long-term character of excess weight," similar to managing conditions like hypertension.
Patient Experiences
Users who have come off the medication describe a sudden return of hunger.
"I experienced something activating and you're instantly ravenous," recalled one woman.
This difficulty is worsened if patients have not adopted sustainable dietary or behavioural modifications during therapy.
Significant Interest
Survey data indicate that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with interest remaining high.
- Adoption is greater among females than men.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while the jabs are powerful agents for weight loss, they are not a permanent cure and lasting health benefits relies on ongoing behavioural support.
