Fresh analysis indicates that individuals who come off blockbuster slimming jabs like Wegovy and Mounjaro may regain shed pounds far faster than those who stop conventional diet and exercise regimens.
Research printed in a prominent health publication points out that while obese individuals often shed substantial amounts of their body weight while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"Users buying these drugs should be aware of the danger of quick rebound weight gain when the medication ends," warns expert Dr. Susan Jebb.
Such speed of recovery means a return to pre-treatment mass in about a year and a half.
Comparing Treatments
The study, which looked at dozens of trials involving over 9,000 of participants, contrasted the effects of GLP-1 agonists with other pills.
Researchers point out that individuals who lose weight through diet and exercise usually see a more gradual weight regain—approximately 0.1 kg a month—after stopping.
Explaining the Quick Rebound
Nutrition scientists propose the mode of action of the jabs accounts for the amplified rebound.
These medications imitate a natural hormone called GLP-1, which moderates hunger.
"Sustained high doses of GLP-1 levels far above than the body's typical production may cause the body to generate a reduced amount of its endogenous hormone, and could diminish responsiveness to its actions," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication leads to hunger is unsuppressed, making binge eating a significant risk."
A Chronic Disease?
Medical guidelines recommend the injections for people with obesity-related health risks, alongside recommended diet and exercise modifications.
A number of clinicians contend that, given the high risk of relapse, the treatment might need to be life-long.
This perspective is echoed by drug manufacturers, who note that the findings "emphasize the chronic character of obesity," comparing it to managing conditions like high blood pressure.
Patient Experiences
Users who have stopped the jabs report a powerful resurgence of hunger.
"It felt as if a trigger activating and you're instantly starving," recalled one woman.
This difficulty is exacerbated if patients have not developed sustainable lifestyle or habit modifications during treatment.
Significant Adoption
Recent estimates indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with demand remaining high.
- Adoption is greater among women compared to men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, researchers emphasize that while these medications are potent agents for weight loss, they are not a magic fix and long-term success hinges on ongoing lifestyle management.
