Fresh analysis indicates that individuals who stop using new slimming jabs like semaglutide or tirzepatide can put back on lost weight much more quickly than those who end traditional lifestyle programs.
Published data in a leading health publication shows that while overweight individuals can lose a large proportion of their body weight while undergoing treatment, the mass is regained at an average rate of 0.8 kg per month after stopping.
"People buying such medications must be aware of the risk of rapid weight regain when the treatment concludes," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a reversion to original weight within about a year and a half.
Weighing Approaches
The study, which examined 37 of studies involving over 9,000 of participants, contrasted the results of GLP-1 agonists with older methods.
Researchers emphasize that people who lose weight through lifestyle changes alone generally have a slower creep back—around 0.1 kg a month—after stopping.
Explaining the Fast Regain
Experts believe the mechanism of the jabs is key to understanding the heightened regain.
These medications mimic a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Artificially providing GLP-1 levels far above than the body's typical production may cause the body to produce less of its own natural GLP-1, and may also lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication leads to hunger is uncontrolled, making excessive eating a significant risk."
A Chronic Disease?
Medical guidelines advise the jabs for people with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians argue that, given the significant potential of weight regain, the treatment should be considered long-term.
This opinion is echoed by pharmaceutical companies, who note that the findings "underscore the chronic nature of excess weight," similar to managing diseases like high blood pressure.
Patient Testimonies
Individuals who have stopped the jabs report a powerful return of appetite.
"It felt as if a switch activating and I was suddenly starving," described one woman.
The struggle is worsened if individuals have not established permanent lifestyle or habit modifications during therapy.
Significant Adoption
Survey data indicate that millions of people in the UK have used these injections in the past year, with interest continuing to grow.
- Use is greater among women compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, clinicians caution that while the jabs are powerful tools for shedding pounds, they are not a standalone cure and lasting health benefits relies on ongoing behavioural changes.
