A recent study suggests that patients who discontinue popular GLP-1 drugs like semaglutide or tirzepatide can put back on reduced body mass far faster than those who stop traditional diet and exercise regimens.
Published data in a major health publication demonstrates that while overweight people frequently drop about a fifth of their body weight while on the medication, the weight returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals using these drugs need to be cognizant of the danger of rapid rebound weight gain when the treatment concludes," stated researcher Dr. Susan Jebb.
This pace of regain means a return to original weight in about one and a half years.
Comparing Approaches
The study, which examined 37 of trials involving thousands of patients, contrasted the effects of GLP-1 agonists with older methods.
The team point out that people who lose weight through lifestyle changes alone generally see a slower weight regain—perhaps 0.1 kg a month—post-intervention.
The Reason for the Fast Rebound
Doctors propose the way of the drugs is key to understanding the accelerated weight return.
The injections imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of the hormone levels far above than normal might result in the body to generate a reduced amount of its own natural GLP-1, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this medication leads to hunger is uncontrolled, making binge eating much more probable."
An Ongoing Condition?
The NHS recommend the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Many experts contend that, due to the significant potential of weight regain, the therapy might need to be ongoing.
This opinion is echoed by drug manufacturers, who say that the findings "highlight the chronic nature of obesity," comparing it to managing conditions like diabetes.
User Testimonies
Individuals who have come off the jabs describe a sudden return of appetite.
"I experienced something that goes on and you become ravenous," recalled an individual.
The struggle is worsened if users have not established lasting lifestyle or habit modifications during treatment.
Significant Use
Recent estimates show that millions of adults in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Use is higher among females compared to men.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, researchers caution that while the jabs are powerful agents for shedding pounds, they are not a permanent solution and long-term success likely depends on combined behavioural management.
