Fresh analysis indicates that individuals who stop using new slimming jabs like Wegovy and Mounjaro can put back on lost weight at a significantly accelerated pace than those who stop traditional diet and exercise plans.
Published data in a major health publication points out that while obese individuals frequently drop substantial amounts of their body weight while on the medication, the weight returns at an estimated rate of 0.8 kg per month after stopping.
"People purchasing such treatments must be informed of the potential of rapid rebound weight gain when the therapy is stopped," stated expert Dr. Susan Jebb.
That rate of regain suggests a reversion to pre-treatment weight in about 18 months.
Comparing Approaches
The study, which reviewed 37 of studies involving thousands of participants, compared the results of GLP-1 agonists with other pills.
Researchers point out that individuals who shed pounds through lifestyle changes alone typically have a more gradual creep back—approximately 0.1 kg a month—post-intervention.
Explaining the Quick Regain
Nutrition scientists suggest the way of the drugs accounts for the heightened rebound.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone levels far above than the body's typical production could lead to the body to produce less of its endogenous GLP-1, and may also lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' leads to hunger is no longer kept in check, making binge eating a significant risk."
A Lifelong Issue?
The NHS suggest the injections for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Many experts argue that, considering the likelihood of relapse, the therapy should be considered life-long.
This view is supported by drug manufacturers, who note that the results "underscore the persistent character of obesity," akin to managing diseases like high blood pressure.
User Accounts
Individuals who have stopped the jabs describe a powerful return of appetite.
"It was like a switch activating and I was suddenly starving," described a patient.
This difficulty is compounded if users have not developed permanent dietary or behavioural changes during therapy.
Significant Adoption
Survey data show that millions of adults in the UK have used these injections in the last 12 months, with desire continuing to grow.
- Use is more common among females than males.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, experts emphasize that while these medications are potent tools for weight loss, they are not a standalone fix and maintained weight loss likely depends on integrated lifestyle changes.
