A recent study reveals that patients who come off blockbuster slimming jabs like Mounjaro or Wegovy may regain shed pounds much more quickly than those who end conventional lifestyle regimens.
Research printed in a prominent health publication shows that while obese people often shed a large proportion of their body weight while undergoing treatment, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.
"Users using these treatments need to be informed of the danger of rapid rebound weight gain when the medication concludes," warns researcher Dr. Susan Jebb.
That rate of regain implies a reversion to original weight in about 18 months.
Analyzing Treatments
The study, which looked at dozens of studies involving thousands of patients, compared the outcomes of these new drugs with conventional dieting.
Scientists point out that individuals who shed pounds through lifestyle changes alone typically see a less rapid weight regain—around 100 grams monthly—after stopping.
Explaining the Fast Rebound
Doctors propose the mode of action of the drugs explains the amplified rebound.
These medications copy a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of the hormone concentrations far above than normal might result in the system to produce less of its endogenous hormone, and could lessen sensitivity to its effects," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement leads to hunger is unsuppressed, making excessive eating a significant risk."
A Lifelong Issue?
The NHS recommend the injections for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians say that, considering the significant potential of weight regain, the therapy should be considered life-long.
This view is supported by pharmaceutical companies, who note that the findings "highlight the persistent character of excess weight," similar to managing diseases like high blood pressure.
Patient Experiences
Users who have discontinued the jabs describe a intense return of cravings.
"It felt as if something that goes on and you're instantly ravenous," said a patient.
This challenge is worsened if patients have not adopted sustainable lifestyle or habit changes during treatment.
Widespread Interest
Survey data indicate that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with demand continuing to grow.
- Adoption is greater among women than males.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the medications through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while the jabs are potent tools for weight loss, they are not a standalone fix and lasting health benefits likely depends on integrated behavioural management.
