Fresh analysis indicates that individuals who discontinue popular slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who stop traditional diet and exercise programs.
Findings released in a prominent health publication demonstrates that while overweight individuals often shed a large proportion of their body weight while undergoing treatment, the weight returns at an average rate of 0.8 kg per month upon discontinuation.
"Individuals using these medications should be cognizant of the danger of quick rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
Such speed of regain implies a reversion to original mass in about 18 months.
Weighing Approaches
The study, which examined dozens of studies involving thousands of participants, compared the outcomes of the injectable medications with older methods.
Scientists note that people who shed pounds through dieting typically see a slower creep back—perhaps 0.1 kg a month—once they finish.
The Reason for the Fast Regain
Doctors suggest the mechanism of the injections is key to understanding the accelerated regain.
The injections copy a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone concentrations far above than normal could lead to the body to generate a reduced amount of its own natural hormone, and may also lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement means hunger is unsuppressed, making excessive eating far more likely."
A Lifelong Condition?
Health authorities advise the jabs for people with obesity-related medical conditions, accompanied by recommended lifestyle changes.
Many experts contend that, due to the high risk of weight regain, the treatment is often ongoing.
This opinion is reinforced by pharmaceutical companies, who note that the results "emphasize the long-term character of excess weight," akin to managing diseases like high blood pressure.
Patient Experiences
People who have discontinued the jabs report a powerful return of appetite.
"It felt as if something flipping and you become starving," recalled a patient.
The struggle is exacerbated if individuals have not established lasting dietary or behavioural modifications during therapy.
Significant Adoption
Figures indicate that millions of people in the UK have used these injections in the past year, with demand remaining high.
- Adoption is more common among women compared to men.
- The middle-aged demographic shows the greatest usage rates.
- Many access the medications through private prescriptions rather than the NHS.
Finally, experts stress that while GLP-1 drugs are powerful agents for shedding pounds, they are not a magic cure and lasting health benefits relies on ongoing lifestyle changes.
