Fresh analysis suggests that patients who come off blockbuster slimming jabs like semaglutide or tirzepatide can put back on lost weight much more quickly than those who stop traditional diet and exercise regimens.
Research printed in a prominent health publication demonstrates that while overweight people can lose a large proportion of their total mass while on the medication, the mass returns at an estimated rate of nearly a kilo each month once they quit.
"Users buying such medications must be aware of the potential of rapid rebound weight gain when the treatment concludes," cautioned researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to pre-treatment mass within about a year and a half.
Weighing Treatments
The analysis, which reviewed dozens of studies involving thousands of patients, compared the effects of GLP-1 agonists with older methods.
The team emphasize that people who shed pounds through lifestyle changes alone usually see a slower creep back—around 100 grams monthly—after stopping.
The Reason for the Rapid Rebound
Nutrition scientists suggest the way of the injections explains the heightened weight return.
These medications copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone concentrations far above than normal might result in the system to produce less of its own natural GLP-1, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' results in appetite is uncontrolled, making overeating much more probable."
A Chronic Issue?
Health authorities advise the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts argue that, due to the significant potential of relapse, the therapy might need to be long-term.
This perspective is supported by pharmaceutical companies, who say that the results "underscore the chronic character of excess weight," similar to managing diseases like hypertension.
User Testimonies
Individuals who have come off the jabs describe a intense return of appetite.
"It felt as if a switch activating and you become ravenous," recalled an individual.
This difficulty is compounded if users have not established sustainable dietary or behavioural modifications during treatment.
Growing Adoption
Survey data indicate that millions of people in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Adoption is more common among females than men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
Finally, researchers stress that while these medications are potent tools for weight loss, they are not a permanent fix and maintained weight loss hinges on combined lifestyle management.
