Fresh analysis reveals that people who come off new slimming jabs like Wegovy and Mounjaro may regain reduced body mass at a significantly accelerated pace than those who stop conventional lifestyle regimens.
Published data in a major medical journal demonstrates that while overweight individuals frequently drop about a fifth of their total mass while on the medication, the weight returns at an average rate of nearly a kilo each month once they quit.
"Users purchasing these treatments need to be informed of the risk of rapid rebound weight gain when the therapy concludes," stated lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to pre-treatment mass in about one and a half years.
Comparing Treatments
The study, which reviewed dozens of trials involving thousands of participants, contrasted the effects of the injectable medications with older methods.
Scientists point out that individuals who lose weight through dieting generally experience a less rapid creep back—perhaps 100 grams monthly—once they finish.
Explaining the Rapid Regain
Experts believe the way of the injections explains the accelerated weight return.
These medications mimic a natural hormone called GLP-1, which moderates appetite.
"Artificially providing GLP-1 concentrations far above than the body's typical production may cause the body to produce less of its own natural hormone, and could reduce sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement results in hunger is uncontrolled, making overeating much more probable."
A Lifelong Issue?
Health authorities suggest the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Many experts say that, due to the likelihood of weight regain, the treatment should be considered ongoing.
This view is supported by drug manufacturers, who note that the findings "emphasize the chronic character of obesity," comparing it to managing diseases like hypertension.
Patient Accounts
Individuals who have stopped the jabs explain a sudden return of appetite.
"I experienced a switch that goes on and you're instantly starving," described a patient.
This challenge is exacerbated if individuals have not developed lasting lifestyle or habit modifications during therapy.
Widespread Use
Survey data indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Adoption is more common among females than men.
- The 40s and 50s demographic shows the highest usage rates.
- Many access the medications through private healthcare rather than the NHS.
Ultimately, experts caution that while these medications are potent agents for weight loss, they are not a magic solution and lasting health benefits relies on ongoing lifestyle management.
