A recent study reveals that people who discontinue popular GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who halt traditional lifestyle programs.
Research printed in a prominent medical journal points out that while overweight people can lose about a fifth of their body weight while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"Individuals purchasing these medications need to be informed of the potential of fast rebound weight gain when the treatment concludes," stated lead investigator Dr. Susan Jebb.
This pace of regain implies a reversion to original mass in about a year and a half.
Comparing Approaches
The analysis, which looked at 37 of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Scientists emphasize that people who shed pounds through dieting usually have a more gradual creep back—perhaps 0.1 kg a month—post-intervention.
The Reason for the Fast Regain
Nutrition scientists propose the mechanism of the injections accounts for the heightened weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of GLP-1 concentrations far above than the body's typical production could lead to the system to produce less of its own natural hormone, and could diminish sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' leads to hunger is uncontrolled, making overeating far more likely."
An Ongoing Condition?
Medical guidelines recommend the injections for individuals with weight-linked health risks, accompanied by recommended lifestyle changes.
Professionals say that, considering the likelihood of relapse, the treatment is often life-long.
This opinion is supported by drug manufacturers, who note that the results "emphasize the persistent nature of excess weight," comparing it to managing conditions like high blood pressure.
User Experiences
People who have come off the jabs describe a intense resurgence of hunger.
"It was like something that goes on and you're instantly starving," described a patient.
This challenge is worsened if patients have not developed sustainable dietary or behavioural modifications during therapy.
Growing Use
Survey data indicate that millions of adults in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Use is more common among females compared to males.
- The 40s and 50s age group shows the greatest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, experts stress that while GLP-1 drugs are potent tools for shedding pounds, they are not a permanent cure and long-term success likely depends on ongoing lifestyle management.
