Fresh analysis indicates that people who stop using new weight-loss injections like semaglutide or tirzepatide may regain reduced body mass much more quickly than those who end traditional diet and exercise plans.
Findings released in a major medical journal shows that while overweight individuals often shed substantial amounts of their total mass while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month once they quit.
"People buying these treatments need to be informed of the danger of fast weight regain when the therapy concludes," warns lead investigator Dr. Susan Jebb.
This pace of recovery suggests a return to starting mass in about one and a half years.
Analyzing Therapies
The analysis, which looked at 37 of trials involving thousands of patients, compared the outcomes of the injectable medications with conventional dieting.
Researchers emphasize that people who lose weight through dieting generally see a slower creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Experts propose the mode of action of the jabs is key to understanding the accelerated regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production could lead to the body to generate a reduced amount of its own natural hormone, and may also reduce responsiveness to its actions," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means hunger is unsuppressed, making overeating much more probable."
An Ongoing Issue?
Health authorities recommend the injections for people with obesity-related health risks, alongside recommended diet and exercise modifications.
Professionals contend that, given the significant potential of weight regain, the treatment might need to be life-long.
This perspective is echoed by pharmaceutical companies, who state that the results "emphasize the long-term character of excess weight," akin to managing diseases like high blood pressure.
User Testimonies
People who have discontinued the medication report a intense return of cravings.
"It felt as if a switch that goes on and you're instantly starving," recalled a patient.
The struggle is exacerbated if patients have not adopted sustainable lifestyle or habit modifications during therapy.
Widespread Use
Figures suggest that millions of people in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Use is greater among females compared to men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
Finally, clinicians emphasize that while the jabs are potent tools for shedding pounds, they are not a magic solution and maintained weight loss likely depends on combined lifestyle management.
