New research suggests that people who come off blockbuster slimming jabs like Mounjaro or Wegovy can put back on reduced body mass at a significantly accelerated pace than those who stop traditional diet and exercise regimens.
Published data in a leading health publication demonstrates that while overweight individuals often shed a large proportion of their body weight while using the jabs, the mass comes back at an average rate of 0.8 kg per month once they quit.
"People buying these drugs need to be informed of the potential of quick rebound weight gain when the treatment is stopped," warns researcher Dr. Susan Jebb.
This pace of recovery suggests a return to pre-treatment weight in about a year and a half.
Comparing Approaches
The research, which examined dozens of trials involving over 9,000 of participants, compared the results of the injectable medications with other pills.
Researchers emphasize that individuals who shed pounds through diet and exercise typically see a slower creep back—around 0.1 kg a month—after stopping.
The Reason for the Quick Rebound
Doctors believe the mechanism of the jabs accounts for the heightened rebound.
The injections copy a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production may cause the body to generate a reduced amount of its endogenous GLP-1, and may also reduce sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' means hunger is unsuppressed, making overeating far more likely."
A Lifelong Disease?
Health authorities recommend the injections for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, considering the high risk of weight regain, the therapy might need to be ongoing.
This view is supported by pharmaceutical companies, who say that the results "underscore the persistent character of obesity," comparing it to managing diseases like hypertension.
Patient Accounts
Individuals who have come off the jabs explain a intense resurgence of appetite.
"I experienced a trigger flipping and you're instantly ravenous," described a patient.
This difficulty is worsened if users have not developed sustainable dietary or behavioural modifications during therapy.
Significant Interest
Survey data show that millions of people in the UK have used these injections in the last 12 months, with interest remaining high.
- Use is greater among females compared to men.
- The middle-aged demographic shows the highest usage rates.
- Many access the medications through private prescriptions rather than public health services.
In conclusion, clinicians stress that while the jabs are potent agents for weight loss, they are not a standalone fix and long-term success relies on integrated behavioural support.
