New research indicates that individuals 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 plans.
Published data in a leading medical journal points out that while obese people frequently drop about a fifth of their total mass while undergoing treatment, the weight returns at an average rate of nearly a kilo each month once they quit.
"Individuals purchasing these medications should be aware of the risk of rapid rebound weight gain when the medication concludes," stated researcher Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment mass within about a year and a half.
Analyzing Approaches
The research, which examined dozens of trials involving thousands of participants, contrasted the effects of GLP-1 agonists with other pills.
Researchers note that people who shed pounds through lifestyle changes alone generally experience a slower creep back—perhaps 100 grams monthly—after stopping.
Explaining the Rapid Regain
Doctors believe the mechanism of the jabs accounts for the heightened rebound.
GLP-1 drugs imitate a natural hormone called GLP-1, which helps regulate hunger.
"Sustained high doses of the hormone levels far above than the body's typical production may cause the system to generate a reduced amount of its endogenous GLP-1, and may also reduce responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' leads to hunger is uncontrolled, making binge eating far more likely."
A Chronic Issue?
Health authorities advise the injections for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Many experts say that, due to the high risk of relapse, the therapy might need to be life-long.
This perspective is reinforced by pharmaceutical companies, who state that the findings "underscore the chronic nature of obesity," akin to managing conditions like hypertension.
Patient Testimonies
Users who have come off the jabs report a sudden return of hunger.
"It felt as if a trigger that goes on and you're instantly starving," recalled one woman.
This difficulty is worsened if patients have not established permanent dietary or behavioural changes during treatment.
Widespread Interest
Recent estimates suggest that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is greater among females compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, experts emphasize that while these medications are effective tools for weight loss, they are not a magic cure and long-term success likely depends on combined behavioural support.
