A recent study reveals that people who stop using popular weight-loss injections like Mounjaro or Wegovy may regain lost weight much more quickly than those who stop traditional lifestyle programs.
Research printed in a prominent medical journal shows that while obese people frequently drop about a fifth of their body weight while on the medication, the weight comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"Users using these medications need to be aware of the potential of quick rebound weight gain when the therapy is stopped," stated lead investigator Dr. Susan Jebb.
That rate of recovery suggests a return to original weight in about 18 months.
Comparing Approaches
The research, which reviewed 37 of studies involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Scientists point out that individuals who shed pounds through diet and exercise typically experience a slower creep back—perhaps 0.1 kg a month—once they finish.
Understanding the Fast Regain
Doctors believe the mode of action of the drugs accounts for the amplified weight return.
These medications imitate a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 concentrations far above than normal could lead to the body to produce less of its own natural GLP-1, and could lessen responsiveness to its effects," noted Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication results in appetite is no longer kept in check, making binge eating a significant risk."
An Ongoing Condition?
Medical guidelines recommend the injections for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Professionals contend that, given the significant potential of relapse, the therapy is often life-long.
This view is echoed by pharmaceutical companies, who note that the results "underscore the persistent nature of excess weight," similar to managing conditions like hypertension.
User Testimonies
Individuals who have stopped the medication report a powerful resurgence of appetite.
"It felt as if a switch activating and you're instantly starving," described a patient.
The struggle is worsened if users have not adopted permanent lifestyle or habit changes during treatment.
Significant Interest
Survey data show that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Adoption is greater among females than men.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers emphasize that while GLP-1 drugs are effective agents for shedding pounds, they are not a permanent fix and lasting health benefits likely depends on ongoing lifestyle changes.
