A recent study suggests that people who come off blockbuster weight-loss injections like Mounjaro or Wegovy may regain shed pounds at a significantly accelerated pace than those who stop traditional lifestyle regimens.
Research printed in a prominent medical journal points out that while obese people frequently drop substantial amounts of their total mass while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"People buying such drugs should be aware of the risk of rapid rebound weight gain when the medication ends," warns researcher Dr. Susan Jebb.
That rate of recovery suggests a return to starting weight in about 18 months.
Comparing Approaches
The analysis, which reviewed 37 of studies involving thousands of patients, contrasted the outcomes of these new drugs with older methods.
The team point out that people who shed pounds through diet and exercise usually see a slower creep back—around 100 grams monthly—once they finish.
Explaining the Fast Rebound
Experts believe the mode of action of the jabs is key to understanding the heightened regain.
The injections copy a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Artificially providing the hormone levels several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication means hunger is uncontrolled, making overeating much more probable."
A Chronic Issue?
Health authorities recommend the jabs for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, due to the high risk of relapse, the treatment might need to be life-long.
This perspective is reinforced by pharmaceutical companies, who state that the findings "emphasize the long-term character of excess weight," comparing it to managing conditions like high blood pressure.
User Testimonies
Individuals who have come off the medication explain a intense return of hunger.
"I experienced a trigger that goes on and I was suddenly ravenous," recalled an individual.
This challenge is exacerbated if individuals have not established permanent dietary or behavioural modifications during treatment.
Widespread Interest
Figures show that millions of adults in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Use is greater among females compared to men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
Finally, researchers caution that while the jabs are effective agents for weight loss, they are not a magic fix and long-term success likely depends on ongoing behavioural changes.
