New research reveals that people who come off blockbuster weight-loss injections like Wegovy and Mounjaro may regain lost weight at a significantly accelerated pace than those who end traditional diet and exercise regimens.
Findings released in a prominent medical journal demonstrates that while overweight people frequently drop substantial amounts of their total mass while using the jabs, the mass is regained at an average rate of nearly a kilo each month once they quit.
"People buying these treatments should be aware of the danger of rapid weight regain when the therapy is stopped," warns expert Dr. Susan Jebb.
This pace of regain implies a reversion to pre-treatment weight within about 18 months.
Analyzing Treatments
The research, which looked at dozens of trials involving thousands of patients, compared the effects of these new drugs with conventional dieting.
Scientists emphasize that individuals who shed pounds through lifestyle changes alone usually have a slower creep back—perhaps 0.1 kg a month—after stopping.
Understanding the Rapid Regain
Nutrition scientists believe the mechanism of the injections is key to understanding the heightened rebound.
These medications copy a natural hormone called GLP-1, which controls feelings of fullness.
"Artificially providing GLP-1 levels far above than the body's typical production may cause the system to produce less of its own natural GLP-1, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement leads to hunger is no longer kept in check, making excessive eating a significant risk."
A Lifelong Condition?
Medical guidelines advise the jabs for individuals with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
A number of clinicians say that, considering the likelihood of weight regain, the therapy might need to be life-long.
This opinion is reinforced by pharmaceutical companies, who note that the findings "emphasize the chronic nature of obesity," similar to managing diseases like high blood pressure.
Patient Testimonies
People who have discontinued the jabs report a powerful return of hunger.
"It felt as if a trigger flipping and I was suddenly starving," said an individual.
This difficulty is compounded if users have not established lasting lifestyle or habit modifications during treatment.
Widespread Use
Recent estimates suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is higher among females compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the drugs through private healthcare rather than public health services.
In conclusion, researchers stress that while these medications are powerful agents for shedding pounds, they are not a standalone fix and maintained weight loss hinges on ongoing behavioural support.
