A recent study reveals that patients who come off new weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds far faster than those who stop conventional diet and exercise plans.
Research printed in a prominent health publication points out that while obese people frequently drop substantial amounts of their total mass while using the jabs, the mass returns at an average rate of nearly a kilo each month after stopping.
"Individuals purchasing these drugs should be aware of the danger of rapid rebound weight gain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to original mass within about one and a half years.
Analyzing Approaches
The analysis, which reviewed dozens of trials involving over 9,000 of participants, contrasted the outcomes of the injectable medications with conventional dieting.
Researchers note that people who shed pounds through diet and exercise generally experience a slower weight regain—perhaps 0.1 kg a month—once they finish.
Understanding the Quick Regain
Doctors propose the way of the injections accounts for the accelerated rebound.
The injections mimic a natural hormone called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone concentrations far above than normal could lead to the system to produce less of its endogenous GLP-1, and may also lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' results in hunger is no longer kept in check, making binge eating a significant risk."
A Lifelong Issue?
Medical guidelines recommend the jabs for people with weight-linked health risks, alongside recommended diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of weight regain, the treatment should be considered life-long.
This opinion is echoed by drug manufacturers, who state that the results "emphasize the chronic character of obesity," similar to managing conditions like hypertension.
Patient Accounts
Users who have discontinued the jabs explain a intense resurgence of hunger.
"It felt as if a trigger flipping and I was suddenly extremely hungry," recalled a patient.
The struggle is compounded if users have not established lasting dietary or behavioural changes during therapy.
Growing Interest
Recent estimates suggest that millions of people in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Use is more common among women than men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
Ultimately, clinicians stress that while these medications are powerful agents for weight loss, they are not a permanent fix and long-term success relies on ongoing lifestyle support.
