Fresh analysis reveals that patients who discontinue new slimming jabs like Wegovy and Mounjaro may regain lost weight at a significantly accelerated pace than those who stop traditional lifestyle plans.
Findings released in a prominent medical journal shows that while overweight people often shed substantial amounts of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month once they quit.
"Individuals using such drugs need to be informed of the potential of fast rebound weight gain when the therapy concludes," warns researcher Dr. Susan Jebb.
Such speed of regain suggests a return to original weight within about one and a half years.
Weighing Treatments
The analysis, which examined dozens of trials involving over 9,000 of patients, compared the effects of GLP-1 agonists with older methods.
Scientists note that individuals who lose weight through dieting usually have a more gradual creep back—around 0.1 kg a month—after stopping.
Understanding the Quick Rebound
Nutrition scientists propose the way of the jabs explains the accelerated regain.
The injections imitate a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of the hormone levels far above than normal could lead to the system to produce less of its endogenous GLP-1, and may also lessen sensitivity to its effects," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication means appetite is uncontrolled, making excessive eating a significant risk."
A Chronic Disease?
Medical guidelines recommend the injections for individuals with obesity-related medical conditions, accompanied by recommended lifestyle changes.
Professionals say that, due to the likelihood of weight regain, the treatment is often ongoing.
This opinion is reinforced by pharmaceutical companies, who state that the results "underscore the long-term character of excess weight," comparing it to managing diseases like hypertension.
Patient Accounts
People who have discontinued the medication describe a intense return of hunger.
"It felt as if something flipping and you become ravenous," said an individual.
This difficulty is worsened if users have not established lasting dietary or behavioural modifications during therapy.
Widespread Use
Survey data suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest continuing to grow.
- Use is more common among females than men.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the medications through private prescriptions rather than public health services.
Finally, experts emphasize that while the jabs are effective tools for shedding pounds, they are not a magic fix and maintained weight loss hinges on integrated lifestyle management.
