A recent study indicates that individuals who come off blockbuster slimming jabs like Mounjaro or Wegovy may regain lost weight far faster than those who halt conventional diet and exercise programs.
Research printed in a leading health publication points out that while obese individuals frequently drop about a fifth of their total mass while on the medication, the mass is regained at an estimated rate of 0.8 kg per month once they quit.
"People purchasing these treatments need to be informed of the potential of fast rebound weight gain when the treatment is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment weight in about 18 months.
The research, which examined 37 of studies involving over 9,000 of participants, compared the effects of GLP-1 agonists with older methods.
The team note that people who shed pounds through dieting typically have a slower weight regain—around 0.1 kg a month—once they finish.
Doctors suggest the mode of action of the jabs is key to understanding the amplified rebound.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its own natural GLP-1, and could reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' results in hunger is uncontrolled, making overeating much more probable."
Medical guidelines suggest the injections for individuals with obesity-related health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians argue that, given the significant potential of weight regain, the treatment might need to be ongoing.
This view is echoed by pharmaceutical companies, who note that the findings "highlight the long-term character of excess weight," akin to managing diseases like hypertension.
Users who have stopped the medication explain a intense return of cravings.
"It was like a switch activating and you're instantly extremely hungry," described one woman.
This challenge is worsened if users have not adopted lasting lifestyle or habit changes during therapy.
Figures indicate that a significant number of people in the UK have used these injections in the last 12 months, with interest being substantial.
In conclusion, researchers emphasize that while the jabs are potent agents for weight loss, they are not a magic solution and long-term success likely depends on combined behavioural changes.
