Fresh analysis reveals that patients who come off blockbuster slimming jabs like Mounjaro or Wegovy may regain shed pounds much more quickly than those who stop conventional diet and exercise regimens.
Published data in a major health publication shows that while obese people often shed substantial amounts of their body weight while undergoing treatment, the weight returns at an estimated rate of nearly a kilo each month once they quit.
"Users using these drugs must be aware of the potential of fast weight regain when the medication ends," cautioned expert Dr. Susan Jebb.
Such speed of regain means a return to starting weight in about a year and a half.
Comparing Treatments
The research, which examined dozens of studies involving thousands of participants, contrasted the outcomes of the injectable medications with other pills.
Researchers note that people who lose weight through lifestyle changes alone usually see a more gradual weight regain—approximately 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Nutrition scientists propose the mode of action of the injections is key to understanding the heightened regain.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone concentrations far above than normal may cause the body to produce less of its endogenous GLP-1, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement results in appetite is unsuppressed, making binge eating far more likely."
A Lifelong Condition?
Health authorities suggest the injections for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
A number of clinicians say that, due to the likelihood of weight regain, the treatment should be considered life-long.
This view is echoed by drug manufacturers, who say that the findings "highlight the persistent nature of obesity," akin to managing conditions like high blood pressure.
User Accounts
Users who have come off the medication describe a sudden return of cravings.
"It was like a switch that goes on and you're instantly ravenous," said a patient.
The struggle is worsened if patients have not adopted lasting lifestyle or habit modifications during therapy.
Growing Use
Survey data show that a significant number of adults in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Adoption is higher among women than males.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, researchers emphasize that while these medications are effective agents for shedding pounds, they are not a magic fix and long-term success likely depends on combined lifestyle changes.
