Fresh analysis reveals that people who come off popular weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who end conventional lifestyle plans.
Findings released in a leading medical journal demonstrates that while overweight people often shed substantial amounts of their total mass while using the jabs, the weight returns at an average rate of 0.8 kg per month once they quit.
"People purchasing these drugs must be informed of the danger of fast rebound weight gain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to original weight within about a year and a half.
Weighing Approaches
The analysis, which examined 37 of trials involving thousands of participants, compared the outcomes of GLP-1 agonists with other pills.
Scientists note that individuals who shed pounds through lifestyle changes alone usually have a more gradual weight regain—around 0.1 kg a month—post-intervention.
Explaining the Fast Regain
Experts suggest the mode of action of the jabs accounts for the amplified rebound.
The injections imitate a natural hormone called GLP-1, which controls appetite.
"Long-term administration of GLP-1 levels several times higher than normal may cause the system to generate a reduced amount of its own natural GLP-1, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication leads to hunger is uncontrolled, making excessive eating a significant risk."
A Chronic Condition?
The NHS advise the injections for people with weight-linked health risks, alongside recommended lifestyle changes.
A number of clinicians contend that, given the significant potential of relapse, the therapy should be considered ongoing.
This opinion is echoed by drug manufacturers, who note that the results "underscore the persistent character of obesity," comparing it to managing conditions like diabetes.
Patient Testimonies
People who have discontinued the jabs describe a sudden return of cravings.
"It felt as if a trigger flipping and you become starving," recalled one woman.
This challenge is worsened if individuals have not developed permanent dietary or behavioural modifications during treatment.
Growing Interest
Figures show that a significant number of adults in the UK have tried these injections in the past year, with interest remaining high.
- Adoption is higher among women compared to males.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the drugs through private healthcare rather than public health services.
In conclusion, researchers stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a standalone cure and maintained weight loss hinges on integrated lifestyle support.
