New research suggests that patients who stop using new weight-loss injections like semaglutide or tirzepatide can put back on shed pounds far faster than those who halt conventional lifestyle regimens.
Findings released in a prominent medical journal points out that while obese people frequently drop a large proportion of their total mass while on the medication, the weight comes back at an estimated rate of nearly a kilo each month once they quit.
"Users buying such medications need to be informed of the potential of rapid rebound weight gain when the treatment concludes," cautioned lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to original mass within about one and a half years.
Analyzing Treatments
The research, which examined dozens of studies involving thousands of participants, contrasted the outcomes of GLP-1 agonists with older methods.
Researchers point out that people who shed pounds through dieting generally have a more gradual weight regain—around 0.1 kg a month—once they finish.
Understanding the Quick Rebound
Nutrition scientists propose the mechanism of the drugs explains the amplified rebound.
GLP-1 drugs mimic a natural hormone called GLP-1, which controls hunger.
"Artificially providing GLP-1 levels far above than normal might result in the body to generate a reduced amount of its own natural hormone, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication results in hunger is unsuppressed, making excessive eating much more probable."
An Ongoing Issue?
Medical guidelines advise the jabs for individuals with weight-linked health risks, alongside recommended lifestyle changes.
A number of clinicians say that, given the likelihood of relapse, the therapy might need to be long-term.
This opinion is reinforced by pharmaceutical companies, who note that the results "emphasize the long-term character of obesity," similar to managing conditions like high blood pressure.
User Accounts
Individuals who have stopped the medication explain a powerful return of hunger.
"It was like a switch activating and you're instantly starving," recalled one woman.
The struggle is exacerbated if individuals have not established sustainable lifestyle or habit modifications during therapy.
Widespread Use
Survey data show that millions of adults in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Use is higher among females than males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
Ultimately, researchers emphasize that while these medications are powerful agents for shedding pounds, they are not a standalone solution and long-term success relies on ongoing lifestyle support.
