Fresh analysis suggests that people who discontinue new slimming jabs like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who stop conventional lifestyle plans.
Research printed in a leading health publication points out that while overweight individuals frequently drop about a fifth of their body weight while undergoing treatment, the mass returns at an average rate of nearly a kilo each month after stopping.
"Individuals buying such drugs should be aware of the potential of rapid weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to original mass in about 18 months.
Weighing Therapies
The study, which looked at dozens of studies involving over 9,000 of participants, contrasted the effects of the injectable medications with conventional dieting.
The team emphasize that people who shed pounds through diet and exercise typically have a slower creep back—perhaps 100 grams monthly—once they finish.
Explaining the Rapid Rebound
Nutrition scientists propose the mechanism of the jabs accounts for the accelerated weight return.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Artificially providing GLP-1 concentrations far above than normal may cause the body to generate a reduced amount of its endogenous hormone, and may also reduce responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication leads to hunger is no longer kept in check, making binge eating much more probable."
A Lifelong Issue?
Medical guidelines advise the injections for individuals with obesity-related health risks, accompanied by recommended lifestyle changes.
A number of clinicians say that, due to the likelihood of weight regain, the treatment might need to be life-long.
This view is reinforced by drug manufacturers, who note that the results "underscore the chronic nature of obesity," akin to managing conditions like diabetes.
User Testimonies
People who have discontinued the jabs report a powerful return of appetite.
"It felt as if a trigger activating and I was suddenly extremely hungry," recalled an individual.
The struggle is worsened if individuals have not established permanent dietary or behavioural changes during therapy.
Widespread Use
Survey data indicate that millions of adults in the UK have used these injections in the last 12 months, with demand being substantial.
- Use is greater among women than males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than public health services.
In conclusion, experts emphasize that while the jabs are potent tools for weight loss, they are not a standalone solution and lasting health benefits likely depends on integrated behavioural changes.
