A recent study indicates that patients who stop using blockbuster weight-loss injections like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who halt traditional diet and exercise programs.
Research printed in a prominent medical journal demonstrates that while obese people can lose substantial amounts of their total mass while using the jabs, the mass comes back at an average rate of 0.8 kg per month once they quit.
"Individuals buying these treatments need to be informed of the potential of quick weight regain when the medication concludes," stated expert Dr. Susan Jebb.
This pace of recovery suggests a return to pre-treatment mass in about 18 months.
Comparing Therapies
The study, which examined 37 of studies involving thousands of patients, compared the results of the injectable medications with other pills.
Researchers note that individuals who lose weight through dieting usually have a more gradual creep back—around 100 grams monthly—once they finish.
Explaining the Rapid Rebound
Nutrition scientists believe the mechanism of the injections explains the heightened regain.
The injections imitate a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone levels far above than normal may cause the system to generate a reduced amount of its endogenous hormone, and could lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement results in appetite is no longer kept in check, making binge eating far more likely."
A Lifelong Issue?
Medical guidelines suggest the injections for people with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts contend that, due to the significant potential of weight regain, the treatment is often ongoing.
This opinion is reinforced by drug manufacturers, who note that the results "underscore the chronic character of excess weight," similar to managing conditions like hypertension.
Patient Experiences
Users who have come off the jabs report a powerful return of cravings.
"It felt as if something flipping and you're instantly starving," described a patient.
This challenge is exacerbated if individuals have not adopted permanent dietary or behavioural changes during therapy.
Widespread Interest
Figures show that a significant number of people in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is higher among females than men.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
Finally, researchers caution that while these medications are powerful tools for shedding pounds, they are not a standalone cure and lasting health benefits likely depends on ongoing lifestyle support.
