Fresh analysis reveals that patients who stop using blockbuster weight-loss injections like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who halt conventional lifestyle plans.
Findings released in a prominent health publication demonstrates that while overweight people frequently drop a large proportion of their total mass while using the jabs, the weight returns at an average rate of 0.8 kg per month once they quit.
"Users buying these drugs need to be informed of the risk of fast rebound weight gain when the medication ends," cautioned researcher Dr. Susan Jebb.
Such speed of regain means a return to original weight within about a year and a half.
Comparing Treatments
The analysis, which reviewed 37 of studies involving thousands of participants, contrasted the effects of GLP-1 agonists with other pills.
The team note that people who shed pounds through lifestyle changes alone generally experience a slower creep back—around 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Doctors propose the way of the drugs explains the accelerated rebound.
The injections imitate a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of GLP-1 levels far above than normal may cause the body to produce less of its endogenous GLP-1, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this medication results in appetite is no longer kept in check, making binge eating far more likely."
A Lifelong Disease?
Health authorities suggest the injections for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
Many experts argue that, due to the significant potential of weight regain, the treatment might need to be long-term.
This opinion is supported by pharmaceutical companies, who say that the results "emphasize the chronic nature of excess weight," akin to managing diseases like hypertension.
Patient Experiences
People who have come off the jabs report a powerful resurgence of appetite.
"It felt as if a trigger activating and you're instantly extremely hungry," recalled one woman.
This challenge is compounded if users have not adopted sustainable dietary or behavioural changes during therapy.
Significant Interest
Survey data show that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.
- Adoption is higher among women compared to men.
- The middle-aged age group shows the greatest usage rates.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, researchers stress that while these medications are potent tools for shedding pounds, they are not a permanent fix and maintained weight loss relies on ongoing behavioural management.
