Fresh analysis indicates that people who stop using blockbuster weight-loss injections like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who halt conventional diet and exercise plans.
Research printed in a leading medical journal demonstrates that while obese individuals can lose substantial amounts of their total mass while on the medication, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"Individuals using such medications need to be aware of the risk of rapid rebound weight gain when the medication ends," cautioned expert Dr. Susan Jebb.
Such speed of recovery suggests a return to starting weight within about 18 months.
Analyzing Treatments
The research, which looked at dozens of trials involving over 9,000 of patients, contrasted the results of the injectable medications with older methods.
Researchers point out that individuals who lose weight through lifestyle changes alone generally see a slower weight regain—around 0.1 kg a month—after stopping.
The Reason for the Fast Rebound
Experts believe the way of the drugs accounts for the accelerated weight return.
The injections imitate a natural hormone called GLP-1, which controls hunger.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its own natural GLP-1, and could diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement results in appetite is unsuppressed, making binge eating much more probable."
A Chronic Disease?
The NHS suggest the jabs for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts contend that, given the likelihood of relapse, the treatment might need to be long-term.
This view is reinforced by drug manufacturers, who say that the findings "underscore the persistent nature of excess weight," comparing it to managing diseases like hypertension.
Patient Testimonies
Users who have stopped the medication explain a sudden return of hunger.
"It was like a trigger that goes on and I was suddenly starving," recalled a patient.
This challenge is worsened if users have not adopted permanent dietary or behavioural changes during therapy.
Widespread Interest
Recent estimates show that a significant number of people in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Adoption is more common among females compared to men.
- The middle-aged age group shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
In conclusion, clinicians stress that while these medications are effective agents for shedding pounds, they are not a magic fix and long-term success hinges on combined behavioural management.
