A recent study indicates that individuals who come off blockbuster slimming jabs like semaglutide or tirzepatide may regain shed pounds much more quickly than those who end traditional diet and exercise plans.
Research printed in a leading health publication points out that while obese individuals frequently drop a large proportion of their body weight while on the medication, the mass comes back at an estimated rate of nearly a kilo each month after stopping.
"People purchasing these medications need to be cognizant of the potential of rapid weight regain when the therapy ends," cautioned researcher Dr. Susan Jebb.
That rate of regain means a reversion to pre-treatment mass in about a year and a half.
Comparing Approaches
The study, which examined 37 of studies involving over 9,000 of participants, compared the outcomes of GLP-1 agonists with older methods.
Researchers note that people who shed pounds through lifestyle changes alone typically experience a less rapid weight regain—around 0.1 kg a month—post-intervention.
Understanding the Quick Rebound
Doctors propose the mechanism of the injections is key to understanding the heightened rebound.
These medications imitate a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of GLP-1 concentrations several times higher than normal could lead to the system to produce less of its own natural hormone, and may also lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Stopping of this GLP-1 'fix' means appetite is uncontrolled, making binge eating much more probable."
An Ongoing Disease?
Medical guidelines suggest the injections for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Professionals contend that, due to the high risk of relapse, the therapy might need to be long-term.
This perspective is echoed by drug manufacturers, who say that the findings "highlight the persistent nature of excess weight," similar to managing conditions like diabetes.
User Testimonies
Individuals who have come off the medication describe a sudden resurgence of hunger.
"It was like something flipping and you become extremely hungry," said an individual.
This challenge is compounded if individuals have not established permanent lifestyle or habit modifications during treatment.
Growing Use
Figures indicate that a significant number of people in the UK have used these injections in the past year, with demand being substantial.
- Use is greater among females than men.
- The 40s and 50s age group shows the greatest level of interest.
- Many access the drugs through private healthcare rather than the NHS.
Finally, clinicians stress that while these medications are potent tools for shedding pounds, they are not a permanent fix and long-term success likely depends on ongoing lifestyle support.
