Fresh analysis indicates that patients who discontinue blockbuster GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who end conventional diet and exercise programs.
Published data in a leading health publication shows that while overweight people often shed substantial amounts of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month after stopping.
"Individuals using these drugs need to be aware of the potential of fast weight regain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
That rate of recovery means a reversion to original mass in about one and a half years.
Comparing Approaches
The research, which examined 37 of trials involving thousands of participants, contrasted the effects of GLP-1 agonists with older methods.
Researchers emphasize that individuals who shed pounds through lifestyle changes alone typically see a slower creep back—around 0.1 kg a month—post-intervention.
Understanding the Quick Regain
Nutrition scientists believe the mode of action of the jabs is key to understanding the accelerated weight return.
The injections imitate a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than the body's typical production might result in the system to produce less of its endogenous hormone, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this medication means appetite is unsuppressed, making binge eating a significant risk."
An Ongoing Disease?
Health authorities recommend the jabs for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Professionals say that, given the likelihood of relapse, the therapy is often life-long.
This opinion is supported by pharmaceutical companies, who say that the results "emphasize the persistent nature of excess weight," akin to managing diseases like high blood pressure.
Patient Accounts
People who have discontinued the jabs report a intense resurgence of cravings.
"It felt as if something that goes on and you're instantly extremely hungry," described an individual.
The struggle is compounded if patients have not adopted permanent dietary or behavioural modifications during therapy.
Growing Use
Survey data indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with desire remaining high.
- Adoption is higher among females compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians caution that while the jabs are powerful agents for shedding pounds, they are not a standalone solution and maintained weight loss hinges on combined behavioural changes.
