A recent study indicates that patients who stop using popular GLP-1 drugs like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who end conventional lifestyle regimens.
Research printed in a prominent health publication points out that while obese people often shed substantial amounts of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month once they quit.
"Individuals purchasing these treatments must be aware of the risk of fast weight regain when the medication ends," warns researcher Dr. Susan Jebb.
Such speed of regain suggests a return to original mass within about a year and a half.
Analyzing Approaches
The study, which looked at dozens of trials involving over 9,000 of participants, compared the effects of GLP-1 agonists with other pills.
Researchers note that people who shed pounds through dieting typically experience a slower creep back—perhaps 0.1 kg a month—post-intervention.
Understanding the Rapid Rebound
Experts believe the mode of action of the injections explains the amplified weight return.
These medications imitate a natural hormone called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production may cause the system to produce less of its endogenous hormone, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' means appetite is uncontrolled, making excessive eating far more likely."
A Chronic Disease?
Medical guidelines recommend the injections for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
A number of clinicians say that, considering the high risk of relapse, the therapy might need to be ongoing.
This opinion is echoed by pharmaceutical companies, who note that the findings "underscore the long-term character of excess weight," akin to managing conditions like hypertension.
Patient Testimonies
Users who have come off the medication explain a powerful return of appetite.
"It was like a trigger that goes on and I was suddenly ravenous," described an individual.
This challenge is exacerbated if patients have not adopted permanent lifestyle or habit modifications during treatment.
Significant Adoption
Figures show that millions of people in the UK have tried weight-loss jabs in the past year, with interest continuing to grow.
- Use is greater among women compared to males.
- The middle-aged demographic shows the highest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while these medications are powerful tools for shedding pounds, they are not a magic fix and long-term success likely depends on integrated behavioural changes.
