New research suggests that patients who discontinue popular GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds far faster than those who end conventional diet and exercise programs.
Research printed in a prominent health publication points out that while overweight individuals frequently drop about a fifth of their total mass while using the jabs, the mass returns at an average rate of 0.8 kg per month after stopping.
"Individuals buying these treatments must be aware of the risk of fast weight regain when the treatment concludes," warns researcher Dr. Susan Jebb.
Such speed of recovery suggests a reversion to original mass within about one and a half years.
Comparing Approaches
The research, which reviewed 37 of trials involving thousands of participants, contrasted the results of these new drugs with conventional dieting.
Researchers point out that individuals who shed pounds through lifestyle changes alone typically have a more gradual weight regain—approximately 0.1 kg a month—post-intervention.
Understanding the Quick Rebound
Doctors believe the mode of action of the injections is key to understanding the heightened regain.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which controls appetite.
"Artificially providing GLP-1 concentrations far above than normal might result in the body to produce less of its endogenous hormone, and could lessen responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' results in hunger is unsuppressed, making overeating much more probable."
A Chronic Disease?
Medical guidelines suggest the jabs for people with obesity-related medical conditions, alongside recommended lifestyle changes.
A number of clinicians contend that, given the likelihood of relapse, the treatment should be considered long-term.
This opinion is reinforced by drug manufacturers, who note that the findings "highlight the chronic nature of excess weight," similar to managing diseases like hypertension.
Patient Testimonies
Users who have stopped the jabs explain a intense return of cravings.
"It was like a trigger activating and you're instantly extremely hungry," recalled one woman.
This difficulty is exacerbated if users have not adopted lasting dietary or behavioural changes during treatment.
Growing Adoption
Figures show that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Adoption is higher among females compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, researchers caution that while the jabs are powerful tools for shedding pounds, they are not a standalone solution and lasting health benefits relies on integrated behavioural management.
