New research suggests that people who discontinue new GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who end traditional lifestyle regimens.
Findings released in a leading health publication points out that while overweight individuals often shed a large proportion of their body weight while on the medication, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"People buying these drugs should be cognizant of the potential of fast weight regain when the treatment is stopped," stated expert Dr. Susan Jebb.
Such speed of recovery implies a return to pre-treatment mass within about 18 months.
Analyzing Treatments
The analysis, which reviewed 37 of studies involving thousands of patients, contrasted the effects of GLP-1 agonists with other pills.
Scientists note that individuals who shed pounds through dieting usually experience a slower weight regain—around 100 grams monthly—once they finish.
The Reason for the Rapid Rebound
Doctors believe the mode of action of the injections is key to understanding the heightened weight return.
GLP-1 drugs copy a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal might result in the system to produce less of its own natural GLP-1, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a nutrition expert.
"Stopping of this hormone supplement means appetite is unsuppressed, making binge eating much more probable."
A Chronic Disease?
The NHS recommend the injections for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians argue that, due to the likelihood of relapse, the treatment should be considered long-term.
This view is echoed by drug manufacturers, who state that the results "highlight the persistent character of obesity," similar to managing diseases like high blood pressure.
Patient Accounts
People who have stopped the jabs describe a sudden resurgence of appetite.
"It felt as if a switch flipping and I was suddenly extremely hungry," recalled an individual.
The struggle is worsened if users have not established permanent lifestyle or habit modifications during therapy.
Significant Adoption
Survey data suggest that millions of people in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is higher among females than men.
- The 40s and 50s demographic shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than the NHS.
Ultimately, clinicians stress that while these medications are powerful tools for shedding pounds, they are not a magic solution and lasting health benefits hinges on integrated behavioural management.
