A recent study suggests that people who come off popular GLP-1 drugs like Wegovy and Mounjaro tend to recover shed pounds much more quickly than those who stop conventional lifestyle plans.
Findings released in a prominent medical journal demonstrates that while overweight people frequently drop about a fifth of their body weight while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month once they quit.
"Users using such medications must be aware of the potential of rapid weight regain when the therapy ends," stated researcher Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment weight in about 18 months.
Comparing Therapies
The research, which examined dozens of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with other pills.
Researchers point out that people who shed pounds through diet and exercise typically have a less rapid creep back—approximately 0.1 kg a month—post-intervention.
The Reason for the Rapid Rebound
Doctors believe the mechanism of the drugs explains the amplified weight return.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production could lead to the system to generate a reduced amount of its own natural GLP-1, and could diminish responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Stopping of this GLP-1 'fix' means appetite is uncontrolled, making excessive eating much more probable."
An Ongoing Disease?
The NHS suggest the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Professionals contend that, given the high risk of relapse, the treatment is often long-term.
This perspective is echoed by pharmaceutical companies, who state that the results "underscore the persistent character of excess weight," similar to managing diseases like high blood pressure.
User Accounts
Individuals who have come off the medication describe a sudden return of hunger.
"It was like a switch activating and you're instantly ravenous," recalled a patient.
This difficulty is exacerbated if patients have not established permanent lifestyle or habit changes during treatment.
Widespread Use
Survey data suggest that millions of people in the UK have tried weight-loss jabs in the past year, with desire continuing to grow.
- Adoption is greater among females than males.
- The 40s and 50s age group shows the highest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
Ultimately, researchers emphasize that while the jabs are potent agents for shedding pounds, they are not a magic cure and lasting health benefits relies on integrated behavioural management.
