New research reveals that individuals who stop using blockbuster slimming jabs like Mounjaro or Wegovy can put back on shed pounds at a significantly accelerated pace than those who stop conventional diet and exercise programs.
Findings released in a prominent medical journal points out that while obese individuals frequently drop substantial amounts of their body weight while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"Individuals using such medications should be aware of the risk of fast rebound weight gain when the medication concludes," cautioned expert Dr. Susan Jebb.
This pace of regain implies a reversion to original weight in about 18 months.
Analyzing Treatments
The analysis, which reviewed dozens of trials involving thousands of participants, compared the outcomes of GLP-1 agonists with conventional dieting.
Researchers emphasize that people who shed pounds through lifestyle changes alone typically see a slower creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Experts propose the way of the jabs explains the amplified weight return.
GLP-1 drugs copy a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of the hormone concentrations far above than the body's typical production might result in the body to generate a reduced amount of its own natural hormone, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication leads to appetite is unsuppressed, making overeating a significant risk."
A Chronic Disease?
The NHS suggest the injections for people with obesity-related medical conditions, alongside prescribed lifestyle changes.
Professionals say that, considering the high risk of relapse, the treatment might need to be long-term.
This view is supported by drug manufacturers, who say that the findings "underscore the long-term nature of excess weight," comparing it to managing diseases like diabetes.
User Testimonies
Users who have stopped the medication describe a powerful return of hunger.
"It felt as if a switch flipping and you're instantly extremely hungry," said a patient.
This challenge is compounded if users have not established sustainable lifestyle or habit modifications during therapy.
Significant Interest
Survey data indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with interest being substantial.
- Use is greater among females than men.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
Finally, researchers caution that while the jabs are effective agents for shedding pounds, they are not a permanent fix and maintained weight loss hinges on combined lifestyle management.
