New research reveals that patients who stop using new GLP-1 drugs like semaglutide or tirzepatide can put back on lost weight much more quickly than those who halt conventional diet and exercise plans.
Findings released in a prominent health publication demonstrates that while obese people frequently drop a large proportion of their body weight while on the medication, the mass returns at an estimated rate of nearly a kilo each month once they quit.
"Individuals buying these medications must be aware of the danger of quick weight regain when the treatment concludes," cautioned lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to pre-treatment weight in about 18 months.
Weighing Treatments
The analysis, which looked at dozens of studies involving thousands of patients, contrasted the outcomes of the injectable medications with older methods.
Researchers note that people who shed pounds through dieting typically see a less rapid creep back—approximately 100 grams monthly—once they finish.
The Reason for the Rapid Rebound
Nutrition scientists believe the mechanism of the injections explains the heightened rebound.
These medications copy a natural hormone called GLP-1, which controls hunger.
"Sustained high doses of the hormone concentrations several times higher than normal might result in the system to produce less of its own natural hormone, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' results in appetite is no longer kept in check, making excessive eating a significant risk."
A Lifelong Disease?
Health authorities suggest the injections for people with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts contend that, given the significant potential of relapse, the treatment is often long-term.
This view is echoed by pharmaceutical companies, who state that the results "emphasize the chronic nature of obesity," comparing it to managing diseases like high blood pressure.
Patient Testimonies
Individuals who have come off the medication explain a powerful return of cravings.
"It was like something flipping and you become starving," recalled a patient.
This challenge is worsened if users have not established sustainable lifestyle or habit changes during therapy.
Significant Use
Survey data show that a significant number of adults in the UK have used these injections in the last 12 months, with demand remaining high.
- Use is higher among women compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than public health services.
In conclusion, researchers emphasize that while GLP-1 drugs are effective tools for weight loss, they are not a magic fix and lasting health benefits relies on ongoing lifestyle support.
