A recent study indicates that patients who stop using popular weight-loss injections like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who end conventional diet and exercise plans.
Research printed in a leading health publication demonstrates that while overweight people frequently drop substantial amounts of their total mass while on the medication, the weight is regained at an average rate of 0.8 kg per month after stopping.
"Individuals using these drugs should be cognizant of the potential of fast rebound weight gain when the treatment is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery means a return to original weight within about 18 months.
Comparing Approaches
The research, which reviewed 37 of studies involving thousands of patients, contrasted the effects of the injectable medications with older methods.
Researchers point out that individuals who lose weight through diet and exercise typically see a slower weight regain—around 0.1 kg a month—post-intervention.
Understanding the Rapid Regain
Experts propose the mechanism of the jabs accounts for the heightened weight return.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of GLP-1 concentrations several times higher than normal might result in the system to produce less of its own natural GLP-1, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this hormone supplement means hunger is uncontrolled, making excessive eating far more likely."
A Chronic Issue?
Medical guidelines suggest the injections for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Professionals argue that, considering the high risk of relapse, the therapy might need to be ongoing.
This view is echoed by drug manufacturers, who say that the results "emphasize the chronic nature of excess weight," comparing it to managing conditions like high blood pressure.
Patient Experiences
People who have come off the medication explain a sudden return of cravings.
"I experienced a trigger flipping and you become starving," described a patient.
This challenge is exacerbated if users have not developed permanent dietary or behavioural changes during treatment.
Significant Interest
Recent estimates show that a significant number of adults in the UK have tried weight-loss jabs in the past year, with desire remaining high.
- Use is higher among women compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, experts caution that while GLP-1 drugs are powerful agents for shedding pounds, they are not a permanent solution and long-term success hinges on integrated lifestyle changes.
