A recent study suggests that individuals who discontinue blockbuster slimming jabs like Mounjaro or Wegovy may regain lost weight at a significantly accelerated pace than those who end conventional lifestyle programs.
Findings released in a prominent health publication shows that while obese individuals often shed substantial amounts of their body weight while using the jabs, the mass comes back at an average rate of 0.8 kg per month once they quit.
"Users using these drugs should be informed of the danger of rapid rebound weight gain when the therapy is stopped," cautioned researcher Dr. Susan Jebb.
This pace of recovery implies a return to pre-treatment mass within about one and a half years.
Analyzing Therapies
The analysis, which reviewed dozens of studies involving over 9,000 of participants, contrasted the effects of the injectable medications with older methods.
Scientists note that people who lose weight through dieting generally see a slower weight regain—around 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Nutrition scientists suggest the mode of action of the jabs accounts for the amplified weight return.
The injections imitate a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing GLP-1 levels far above than normal could lead to the system to produce less of its endogenous GLP-1, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement means hunger is no longer kept in check, making binge eating a significant risk."
A Lifelong Condition?
The NHS suggest the jabs for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts say that, due to the likelihood of weight regain, the treatment might need to be long-term.
This opinion is supported by drug manufacturers, who note that the results "underscore the long-term nature of excess weight," similar to managing conditions like high blood pressure.
User Accounts
People who have stopped the medication describe a sudden return of appetite.
"It was like a switch activating and you become extremely hungry," recalled one woman.
The struggle is compounded if patients have not adopted permanent lifestyle or habit modifications during treatment.
Significant Interest
Survey data indicate that millions of people in the UK have tried weight-loss jabs in the last 12 months, with demand being substantial.
- Adoption is greater among women compared to males.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Ultimately, clinicians stress that while these medications are powerful tools for weight loss, they are not a standalone fix and maintained weight loss likely depends on combined lifestyle support.
