A recent study suggests that people who discontinue blockbuster slimming jabs like semaglutide or tirzepatide may regain lost weight far faster than those who halt traditional lifestyle regimens.
Published data in a prominent medical journal points out that while obese people can lose a large proportion of their total mass while undergoing treatment, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"Individuals purchasing these drugs need to be informed of the potential of quick rebound weight gain when the treatment concludes," cautioned lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to pre-treatment mass within about 18 months.
Analyzing Therapies
The study, which reviewed dozens of studies involving thousands of participants, compared the results of GLP-1 agonists with older methods.
Scientists point out that people who shed pounds through dieting usually see a more gradual creep back—approximately 100 grams monthly—post-intervention.
The Reason for the Quick Regain
Doctors suggest the mechanism of the jabs accounts for the heightened weight return.
These medications imitate a natural hormone called GLP-1, which moderates feelings of fullness.
"Artificially providing the hormone levels far above than the body's typical production may cause the body to generate a reduced amount of its endogenous GLP-1, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' results in appetite is unsuppressed, making binge eating a significant risk."
A Lifelong Condition?
Medical guidelines advise the injections for people with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians say that, due to the significant potential of relapse, the therapy might need to be life-long.
This view is supported by pharmaceutical companies, who say that the results "underscore the chronic character of excess weight," akin to managing conditions like hypertension.
User Testimonies
Individuals who have discontinued the jabs explain a powerful return of appetite.
"It was like a switch that goes on and you're instantly extremely hungry," recalled a patient.
This challenge is exacerbated if individuals have not adopted lasting lifestyle or habit changes during treatment.
Widespread Adoption
Figures show that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is higher among women than men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
Finally, experts emphasize that while these medications are potent tools for shedding pounds, they are not a standalone solution and lasting health benefits hinges on ongoing lifestyle changes.
