New research reveals that individuals who stop using popular weight-loss injections like Mounjaro or Wegovy can put back on reduced body mass far faster than those who halt traditional lifestyle programs.
Published data in a major health publication shows that while overweight individuals frequently drop substantial amounts of their total mass while using the jabs, the mass comes back at an average rate of 0.8 kg per month once they quit.
"People purchasing these drugs must be cognizant of the danger of fast rebound weight gain when the treatment ends," cautioned expert Dr. Susan Jebb.
That rate of regain means a reversion to starting weight in about 18 months.
Analyzing Approaches
The research, which reviewed 37 of trials involving thousands of participants, contrasted the outcomes of the injectable medications with other pills.
Scientists emphasize that individuals who lose weight through diet and exercise generally experience a slower weight regain—perhaps 0.1 kg a month—once they finish.
The Reason for the Rapid Rebound
Experts believe the mode of action of the injections explains the heightened regain.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 levels several times higher than normal may cause the system to produce less of its own natural GLP-1, and could lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement means appetite is unsuppressed, making binge eating a significant risk."
An Ongoing Condition?
Health authorities recommend the injections for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Professionals contend that, considering the significant potential of weight regain, the therapy is often life-long.
This view is reinforced by pharmaceutical companies, who note that the results "underscore the chronic nature of obesity," similar to managing diseases like high blood pressure.
Patient Testimonies
Users who have discontinued the medication describe a intense resurgence of appetite.
"I experienced a switch activating and you're instantly extremely hungry," said a patient.
The struggle is compounded if patients have not developed permanent lifestyle or habit changes during treatment.
Significant Adoption
Recent estimates indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire being substantial.
- Adoption is more common among females than men.
- The middle-aged age group shows the greatest usage rates.
- A large proportion access the medications through private healthcare rather than public health services.
Ultimately, researchers emphasize that while these medications are effective agents for shedding pounds, they are not a standalone fix and long-term success relies on ongoing behavioural changes.
