New research reveals that individuals who come off popular slimming jabs like Mounjaro or Wegovy may regain reduced body mass far faster than those who end conventional diet and exercise regimens.
Research printed in a prominent medical journal demonstrates that while overweight individuals often shed substantial amounts of their total mass while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month once they quit.
"Users buying these drugs should be aware of the risk of fast weight regain when the treatment concludes," cautioned researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to original weight within about 18 months.
Analyzing Approaches
The research, which looked at dozens of studies involving over 9,000 of patients, compared the outcomes of these new drugs with other pills.
Scientists note that individuals who lose weight through diet and exercise typically see a slower creep back—perhaps 100 grams monthly—once they finish.
Explaining the Fast Rebound
Experts suggest the mode of action of the injections is key to understanding the accelerated regain.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 concentrations far above than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and could reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement means hunger is unsuppressed, making binge eating far more likely."
An Ongoing Issue?
Medical guidelines recommend the injections for individuals with obesity-related health risks, alongside recommended lifestyle changes.
Professionals say that, considering the likelihood of relapse, the therapy might need to be ongoing.
This opinion is echoed by pharmaceutical companies, who state that the results "highlight the persistent character of obesity," comparing it to managing conditions like high blood pressure.
Patient Experiences
Users who have come off the jabs explain a powerful return of cravings.
"It was like a trigger that goes on and you're instantly ravenous," described an individual.
The struggle is compounded if individuals have not adopted lasting lifestyle or habit modifications during treatment.
Widespread Interest
Survey data suggest that a significant number of adults in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Adoption is more common among females than males.
- The 40s and 50s age group shows the highest usage rates.
- Many obtain the medications through private healthcare rather than the NHS.
Finally, experts caution that while these medications are effective tools for weight loss, they are not a permanent cure and lasting health benefits relies on integrated lifestyle changes.
