Fresh analysis reveals that patients who come off new slimming jabs like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who halt conventional diet and exercise regimens.
Published data in a leading medical journal shows that while overweight people can lose a large proportion of their body weight while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"Users buying these treatments need to be informed of the potential of quick rebound weight gain when the therapy is stopped," stated expert Dr. Susan Jebb.
Such speed of regain means a reversion to pre-treatment weight in about a year and a half.
Weighing Therapies
The research, which looked at dozens of trials involving over 9,000 of patients, contrasted the outcomes of these new drugs with older methods.
The team emphasize that people who shed pounds through dieting usually experience a more gradual creep back—around 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Experts propose the way of the drugs explains the amplified regain.
These medications imitate a natural hormone called GLP-1, which moderates hunger.
"Long-term administration of GLP-1 concentrations far above than the body's typical production could lead to the body to produce less of its endogenous GLP-1, and could reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement means appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Disease?
The NHS suggest the jabs for people with obesity-related health risks, alongside recommended diet and exercise modifications.
A number of clinicians say that, considering the likelihood of relapse, the therapy is often ongoing.
This view is reinforced by drug manufacturers, who note that the results "highlight the long-term character of obesity," comparing it to managing diseases like diabetes.
Patient Experiences
Individuals who have come off the medication describe a sudden resurgence of hunger.
"It felt as if a trigger flipping and I was suddenly starving," described one woman.
This challenge is worsened if individuals have not developed permanent lifestyle or habit modifications during treatment.
Widespread Use
Survey data show that a significant number of adults in the UK have tried these injections in the past year, with desire remaining high.
- Use is greater among females than men.
- The 40s and 50s demographic shows the greatest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, experts caution that while GLP-1 drugs are powerful tools for shedding pounds, they are not a permanent fix and long-term success likely depends on integrated behavioural changes.
