New research reveals that patients who come off blockbuster weight-loss injections like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who stop traditional diet and exercise plans.
Published data in a leading medical journal shows that while overweight people often shed substantial amounts of their total mass while using the jabs, the mass is regained at an average rate of nearly a kilo each month once they quit.
"Users purchasing these drugs must be cognizant of the danger of quick rebound weight gain when the therapy is stopped," cautioned researcher Dr. Susan Jebb.
That rate of regain means a reversion to pre-treatment weight in about one and a half years.
Weighing Approaches
The research, which examined dozens of studies involving thousands of patients, contrasted the outcomes of the injectable medications with other pills.
Scientists emphasize that people who lose weight through diet and exercise usually experience a slower weight regain—around 0.1 kg a month—after stopping.
The Reason for the Rapid Regain
Doctors propose the mechanism of the jabs accounts for the amplified weight return.
GLP-1 drugs mimic a natural hormone called GLP-1, which controls hunger.
"Sustained high doses of the hormone levels far above than normal might result in the system to produce less of its endogenous hormone, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication results in appetite is uncontrolled, making excessive eating much more probable."
A Chronic Disease?
The NHS suggest the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts argue that, due to the likelihood of relapse, the treatment should be considered ongoing.
This perspective is echoed by drug manufacturers, who note that the findings "highlight the chronic nature of excess weight," comparing it to managing conditions like hypertension.
User Testimonies
People who have discontinued the medication describe a intense resurgence of appetite.
"It felt as if a trigger activating and you're instantly extremely hungry," recalled a patient.
This challenge is worsened if users have not developed sustainable lifestyle or habit modifications during treatment.
Significant Interest
Recent estimates show that millions of people in the UK have tried these injections in the last 12 months, with interest remaining high.
- Use is more common among females than males.
- The middle-aged age group shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than public health services.
Finally, experts caution that while these medications are potent agents for shedding pounds, they are not a magic fix and maintained weight loss likely depends on integrated behavioural changes.
