New research reveals that people who stop using blockbuster slimming jabs like Mounjaro or Wegovy may regain shed pounds much more quickly than those who halt traditional diet and exercise regimens.
Published data in a leading medical journal demonstrates that while overweight individuals can lose substantial amounts of their total mass while on the medication, the mass comes back at an estimated rate of 0.8 kg per month once they quit.
"Users using these medications should be cognizant of the potential of fast weight regain when the medication is stopped," stated expert Dr. Susan Jebb.
This pace of regain means a reversion to original mass within about one and a half years.
Analyzing Therapies
The research, which reviewed dozens of trials involving thousands of participants, contrasted the outcomes of these new drugs with other pills.
The team emphasize that individuals who lose weight through diet and exercise typically see a more gradual weight regain—perhaps 100 grams monthly—after stopping.
The Reason for the Rapid Regain
Nutrition scientists believe the way of the injections accounts for the heightened weight return.
GLP-1 drugs mimic a body's own chemical called GLP-1, which controls feelings of fullness.
"Long-term administration of the hormone concentrations far above than the body's typical production may cause the system to produce less of its endogenous hormone, and could diminish sensitivity to its effects," said Dr. Adam Collins, a dietetics expert.
"Stopping of this medication means hunger is no longer kept in check, making overeating far more likely."
A Lifelong Condition?
Health authorities advise the jabs for individuals with obesity-related health risks, alongside prescribed diet and exercise modifications.
A number of clinicians contend that, given the likelihood of weight regain, the therapy might need to be long-term.
This opinion is reinforced by pharmaceutical companies, who say that the findings "underscore the persistent nature of obesity," similar to managing diseases like hypertension.
User Testimonies
Users who have come off the medication report a intense resurgence of cravings.
"It was like something that goes on and I was suddenly starving," described a patient.
This challenge is worsened if users have not developed sustainable dietary or behavioural changes during treatment.
Growing Adoption
Figures show that millions of adults in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Adoption is more common among females compared to males.
- The middle-aged age group shows the highest level of interest.
- A large proportion access the drugs through private healthcare rather than the NHS.
In conclusion, clinicians stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a permanent fix and long-term success likely depends on integrated lifestyle support.
