New research indicates that individuals who come off blockbuster slimming jabs like Mounjaro or Wegovy can put back on shed pounds at a significantly accelerated pace than those who halt conventional diet and exercise programs.
Findings released in a major medical journal demonstrates that while obese individuals can lose substantial amounts of their total mass while on the medication, the weight is regained at an average rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing such medications need to be informed of the potential of rapid weight regain when the therapy is stopped," cautioned researcher Dr. Susan Jebb.
Such speed of regain means a return to pre-treatment mass within about a year and a half.
Weighing Therapies
The analysis, which examined 37 of trials involving thousands of patients, contrasted the results of these new drugs with older methods.
Researchers note that individuals who lose weight through dieting generally have a more gradual creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Doctors propose the way of the drugs explains the heightened regain.
The injections imitate a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production could lead to the body to generate a reduced amount of its endogenous GLP-1, and could diminish sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement leads to appetite is no longer kept in check, making overeating much more probable."
An Ongoing Disease?
Medical guidelines suggest the injections for people with obesity-related health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of weight regain, the therapy is often ongoing.
This view is supported by pharmaceutical companies, who note that the findings "highlight the long-term nature of excess weight," comparing it to managing diseases like high blood pressure.
User Accounts
Users who have discontinued the medication report a powerful resurgence of appetite.
"It was like a switch that goes on and I was suddenly ravenous," described one woman.
This challenge is worsened if users have not developed lasting lifestyle or habit modifications during treatment.
Significant Use
Figures indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with interest remaining high.
- Use is greater among females than men.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
Finally, clinicians emphasize that while these medications are effective tools for shedding pounds, they are not a permanent fix and lasting health benefits relies on ongoing lifestyle support.
