A recent study suggests that individuals who discontinue popular weight-loss injections like semaglutide or tirzepatide can put back on shed pounds far faster than those who stop conventional lifestyle plans.
Research printed in a leading medical journal shows that while obese individuals can lose about a fifth of their body weight while using the jabs, the mass returns at an average rate of nearly a kilo each month once they quit.
"Individuals buying these medications should be informed of the risk of rapid rebound weight gain when the therapy concludes," warns lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to pre-treatment weight in about one and a half years.
Analyzing Therapies
The analysis, which reviewed dozens of trials involving thousands of participants, contrasted the results of these new drugs with conventional dieting.
Scientists emphasize that people who lose weight through dieting typically experience a more gradual creep back—approximately 0.1 kg a month—post-intervention.
Explaining the Quick Regain
Nutrition scientists suggest the way of the drugs explains the accelerated rebound.
These medications copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing GLP-1 levels far above than normal might result in the system to produce less of its endogenous hormone, and may also lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' results in hunger is unsuppressed, making overeating far more likely."
A Lifelong Condition?
Health authorities recommend the injections for individuals with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
A number of clinicians contend that, considering the high risk of relapse, the therapy might need to be ongoing.
This opinion is supported by drug manufacturers, who say that the results "emphasize the persistent nature of obesity," akin to managing conditions like hypertension.
Patient Experiences
Individuals who have come off the jabs explain a powerful resurgence of appetite.
"It felt as if something activating and you become ravenous," described an individual.
The struggle is worsened if users have not developed lasting dietary or behavioural modifications during treatment.
Widespread Use
Recent estimates suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Adoption is higher among women than males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion access the medications through private healthcare rather than public health services.
Finally, clinicians stress that while these medications are potent tools for weight loss, they are not a permanent solution and long-term success relies on integrated behavioural support.
