New research suggests that individuals who stop using popular slimming jabs like semaglutide or tirzepatide may regain reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle regimens.
Published data in a major health publication points out that while overweight people often shed substantial amounts of their total mass while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"People using such treatments must be informed of the risk of rapid rebound weight gain when the therapy ends," cautioned expert Dr. Susan Jebb.
That rate of recovery means a reversion to pre-treatment mass in about 18 months.
Comparing Treatments
The study, which looked at dozens of studies involving thousands of participants, contrasted the effects of the injectable medications with older methods.
Researchers point out that individuals who lose weight through lifestyle changes alone typically see a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Experts believe the way of the injections explains the heightened weight return.
These medications mimic a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Long-term administration of the hormone concentrations several times higher than normal could lead to the system to generate a reduced amount of its own natural hormone, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement results in appetite is unsuppressed, making excessive eating a significant risk."
A Chronic Issue?
Health authorities advise the injections for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Many experts contend that, considering the likelihood of relapse, the treatment might need to be life-long.
This view is reinforced by drug manufacturers, who note that the results "emphasize the long-term character of obesity," akin to managing diseases like hypertension.
User Testimonies
People who have discontinued the medication explain a intense resurgence of cravings.
"It felt as if a trigger activating and I was suddenly starving," recalled one woman.
The struggle is worsened if patients have not established sustainable lifestyle or habit changes during treatment.
Significant Adoption
Figures suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Use is greater among women than men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion obtain the medications through private healthcare rather than public health services.
Finally, clinicians emphasize that while these medications are effective agents for weight loss, they are not a magic cure and long-term success relies on ongoing lifestyle support.
