Fresh analysis suggests that individuals who discontinue popular slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle plans.
Findings released in a prominent medical journal shows that while obese individuals often shed about a fifth of their total mass while using the jabs, the weight is regained at an average rate of nearly a kilo each month after stopping.
"Users buying these drugs must be informed of the potential of rapid weight regain when the medication ends," stated lead investigator Dr. Susan Jebb.
That rate of regain means a return to original weight within about one and a half years.
Weighing Therapies
The analysis, which reviewed 37 of trials involving thousands of participants, compared the outcomes of the injectable medications with other pills.
Researchers note that individuals who shed pounds through lifestyle changes alone typically experience a more gradual weight regain—approximately 0.1 kg a month—post-intervention.
Understanding the Quick Rebound
Doctors propose the mechanism of the drugs is key to understanding the amplified rebound.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of the hormone concentrations far above than normal may cause the body to produce less of its own natural hormone, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement results in appetite is uncontrolled, making binge eating much more probable."
An Ongoing Issue?
The NHS suggest the injections for individuals with obesity-related health risks, accompanied by recommended lifestyle changes.
Professionals say that, given the significant potential of relapse, the treatment is often life-long.
This view is echoed by drug manufacturers, who state that the findings "highlight the long-term nature of obesity," comparing it to managing conditions like diabetes.
User Experiences
People who have stopped the medication describe a intense return of cravings.
"It felt as if something that goes on and you become extremely hungry," recalled one woman.
This difficulty is worsened if users have not developed lasting lifestyle or habit modifications during therapy.
Widespread Use
Recent estimates show that a significant number of people in the UK have tried these injections in the last 12 months, with demand remaining high.
- Adoption is higher among women compared to males.
- The middle-aged demographic shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, researchers caution that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic solution and lasting health benefits likely depends on integrated lifestyle changes.
