A recent study suggests that individuals who stop using popular weight-loss injections like Mounjaro or Wegovy may regain lost weight far faster than those who end conventional lifestyle plans.
Published data in a leading health publication demonstrates that while overweight people often shed about a fifth of their body weight while using the jabs, the mass returns at an average rate of 0.8 kg per month once they quit.
"Individuals buying these medications need to be informed of the potential of fast rebound weight gain when the treatment is stopped," warns researcher Dr. Susan Jebb.
This pace of recovery suggests a reversion to original mass within about one and a half years.
Comparing Approaches
The study, which looked at dozens of studies involving over 9,000 of participants, compared the results of these new drugs with older methods.
Scientists note that individuals who shed pounds through dieting generally have a slower weight regain—perhaps 100 grams monthly—once they finish.
Understanding the Rapid Regain
Nutrition scientists suggest the mechanism of the injections explains the amplified rebound.
These medications mimic a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of GLP-1 concentrations far above than normal could lead to the system to produce less of its own natural hormone, and may also diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement leads to appetite is unsuppressed, making overeating much more probable."
A Chronic Condition?
Medical guidelines recommend the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
A number of clinicians contend that, considering the likelihood of weight regain, the therapy is often long-term.
This opinion is reinforced by drug manufacturers, who note that the findings "highlight the long-term character of excess weight," similar to managing conditions like diabetes.
Patient Testimonies
Individuals who have discontinued the medication report a sudden resurgence of hunger.
"It was like a switch flipping and you're instantly ravenous," recalled a patient.
This challenge is exacerbated if individuals have not adopted permanent lifestyle or habit modifications during treatment.
Widespread Adoption
Recent estimates suggest that a significant number of people in the UK have tried these injections in the past year, with desire remaining high.
- Use is greater among women compared to men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than public health services.
Finally, experts caution that while the jabs are powerful agents for weight loss, they are not a standalone cure and maintained weight loss likely depends on combined lifestyle management.
