New research reveals that people who stop using new weight-loss injections like semaglutide or tirzepatide may regain shed pounds much more quickly than those who halt traditional lifestyle programs.
Published data in a major health publication demonstrates that while obese people can lose a large proportion of their total mass while using the jabs, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"Users buying these treatments need to be informed of the potential of rapid rebound weight gain when the treatment concludes," stated expert Dr. Susan Jebb.
That rate of recovery implies a return to starting mass within about one and a half years.
Analyzing Treatments
The analysis, which looked at dozens of trials involving over 9,000 of patients, compared the outcomes of the injectable medications with conventional dieting.
Researchers point out that individuals who shed pounds through dieting generally see a more gradual creep back—approximately 100 grams monthly—after stopping.
Understanding the Fast Regain
Doctors suggest the way of the injections accounts for the accelerated weight return.
These medications imitate a natural hormone called GLP-1, which moderates appetite.
"Artificially providing the hormone concentrations several times higher than normal may cause the system to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' results in hunger is uncontrolled, making overeating far more likely."
A Chronic Condition?
The NHS advise the jabs for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
Many experts say that, due to the high risk of relapse, the treatment is often life-long.
This view is reinforced by pharmaceutical companies, who say that the results "highlight the long-term character of excess weight," similar to managing conditions like hypertension.
Patient Testimonies
Users who have come off the medication describe a intense return of cravings.
"I experienced a switch that goes on and you're instantly extremely hungry," described one woman.
This challenge is exacerbated if patients have not established lasting lifestyle or habit modifications during treatment.
Growing Adoption
Figures show that millions of people in the UK have tried these injections in the last 12 months, with desire remaining high.
- Adoption is greater among females compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than the NHS.
Finally, clinicians caution that while these medications are effective agents for shedding pounds, they are not a magic fix and maintained weight loss likely depends on ongoing behavioural management.
