New research reveals that patients who stop using blockbuster slimming jabs like Mounjaro or Wegovy may regain shed pounds far faster than those who halt conventional lifestyle regimens.
Published data in a major health publication shows 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 0.8 kg per month once they quit.
"Users buying such drugs should be cognizant of the potential of rapid weight regain when the therapy is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of recovery means a return to pre-treatment mass in about one and a half years.
Analyzing Therapies
The study, which reviewed 37 of studies involving thousands of participants, compared the outcomes of GLP-1 agonists with conventional dieting.
The team point out that individuals who shed pounds through diet and exercise typically experience a slower weight regain—perhaps 100 grams monthly—after stopping.
Understanding the Rapid Regain
Doctors propose the mode of action of the injections explains the heightened regain.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone levels far above than normal may cause the system to produce less of its endogenous GLP-1, and could lessen responsiveness to its effects," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication results in appetite is unsuppressed, making overeating much more probable."
A Lifelong Issue?
Medical guidelines advise the jabs for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Professionals argue that, given the high risk of weight regain, the therapy might need to be life-long.
This opinion is reinforced by pharmaceutical companies, who say that the findings "underscore the chronic character of obesity," similar to managing diseases like diabetes.
User Accounts
Individuals who have discontinued the medication report a sudden return of cravings.
"It felt as if a switch activating and I was suddenly ravenous," said one woman.
The struggle is compounded if patients have not established lasting lifestyle or habit changes during treatment.
Significant Adoption
Survey data suggest that a significant number of people in the UK have used these injections in the last 12 months, with demand being substantial.
- Use is more common among women compared to males.
- The middle-aged age group shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while these medications are powerful agents for weight loss, they are not a magic fix and lasting health benefits hinges on ongoing behavioural management.
