A recent study reveals that individuals who stop using new slimming jabs like semaglutide or tirzepatide tend to recover shed pounds far faster than those who stop traditional diet and exercise plans.
Published data in a major medical journal demonstrates that while overweight people often shed substantial amounts of their total mass while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month after stopping.
"Users purchasing such treatments must be informed of the potential of quick weight regain when the therapy concludes," stated researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to pre-treatment weight within about 18 months.
Analyzing Approaches
The research, which reviewed 37 of studies involving thousands of patients, contrasted the results of GLP-1 agonists with conventional dieting.
Researchers point out that people who shed pounds through lifestyle changes alone usually experience a slower weight regain—approximately 100 grams monthly—after stopping.
Understanding the Fast Rebound
Experts believe the way of the injections explains the accelerated rebound.
These medications mimic a body's own chemical called GLP-1, which controls appetite.
"Artificially providing GLP-1 levels far above than normal may cause the system to produce less of its endogenous hormone, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' leads to hunger is uncontrolled, making overeating a significant risk."
A Chronic Condition?
Medical guidelines advise the jabs for people with weight-linked health risks, alongside recommended lifestyle changes.
Professionals say that, given the likelihood of relapse, the therapy should be considered life-long.
This view is reinforced by drug manufacturers, who state that the findings "underscore the long-term nature of excess weight," akin to managing conditions like diabetes.
User Accounts
Users who have stopped the jabs describe a sudden resurgence of hunger.
"I experienced something flipping and you're instantly extremely hungry," described one woman.
This difficulty is worsened if users have not adopted sustainable dietary or behavioural modifications during treatment.
Significant Adoption
Survey data suggest that millions of adults in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Adoption is greater among women compared to males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Finally, researchers caution that while these medications are potent tools for weight loss, they are not a permanent cure and maintained weight loss likely depends on integrated behavioural support.
