A recent study indicates that individuals who come off blockbuster GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass much more quickly than those who halt traditional diet and exercise regimens.
Published data in a leading medical journal demonstrates that while overweight individuals often shed substantial amounts of their body weight while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"People buying such drugs must be cognizant of the risk of fast weight regain when the treatment concludes," warns lead investigator Dr. Susan Jebb.
That rate of regain implies a return to original mass in about one and a half years.
Comparing Approaches
The research, which examined dozens of trials involving over 9,000 of participants, compared the results of GLP-1 agonists with other pills.
Researchers point out that people who lose weight through diet and exercise typically see a less rapid creep back—perhaps 100 grams monthly—after stopping.
Understanding the Rapid Regain
Doctors suggest the mechanism of the injections accounts for the amplified regain.
GLP-1 drugs imitate a natural hormone called GLP-1, which moderates appetite.
"Artificially providing the hormone levels far above than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and may also reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' results in appetite is uncontrolled, making binge eating much more probable."
A Lifelong Disease?
The NHS advise the injections for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Many experts contend that, given the likelihood of weight regain, the treatment should be considered long-term.
This perspective is reinforced by drug manufacturers, who state that the findings "emphasize the chronic character of excess weight," akin to managing conditions like diabetes.
User Experiences
People who have come off the medication explain a intense return of cravings.
"It was like a trigger flipping and you become extremely hungry," described a patient.
The struggle is compounded if patients have not established lasting dietary or behavioural changes during therapy.
Widespread Interest
Survey data show that millions of people in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Use is greater among females than males.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, experts emphasize that while GLP-1 drugs are effective tools for shedding pounds, they are not a permanent solution and long-term success likely depends on ongoing behavioural support.
