New research reveals that patients who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy can put back on shed pounds far faster than those who end conventional lifestyle programs.
Published data in a prominent health publication points out that while overweight people often shed substantial amounts of their total mass while undergoing treatment, the weight comes back at an estimated rate of nearly a kilo each month after stopping.
"Users buying such medications should be cognizant of the risk of rapid rebound weight gain when the therapy concludes," warns researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to original mass within about a year and a half.
Weighing Therapies
The analysis, which reviewed dozens of trials involving thousands of participants, compared the results of the injectable medications with older methods.
Researchers point out that individuals who lose weight through diet and exercise generally have a less rapid weight regain—around 0.1 kg a month—after stopping.
Understanding the Fast Rebound
Doctors propose the way of the drugs accounts for the heightened rebound.
The injections imitate a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone levels several times higher than normal may cause the body to produce less of its endogenous GLP-1, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication results in appetite is no longer kept in check, making excessive eating far more likely."
A Chronic Issue?
Medical guidelines recommend the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
A number of clinicians argue that, due to the significant potential of weight regain, the therapy might need to be life-long.
This opinion is reinforced by pharmaceutical companies, who say that the results "underscore the persistent nature of excess weight," comparing it to managing conditions like diabetes.
User Accounts
Individuals who have stopped the jabs explain a intense return of cravings.
"It was like something flipping and you're instantly ravenous," said an individual.
The struggle is exacerbated if patients have not adopted sustainable dietary or behavioural changes during treatment.
Widespread Use
Recent estimates suggest that millions of adults in the UK have tried these injections in the last 12 months, with demand continuing to grow.
- Adoption is greater among women compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion obtain the medications through private prescriptions rather than public health services.
Finally, researchers emphasize that while GLP-1 drugs are potent tools for shedding pounds, they are not a magic solution and maintained weight loss relies on integrated lifestyle management.
