A recent study indicates that individuals who discontinue new weight-loss injections like semaglutide or tirzepatide can put back on lost weight far faster than those who stop conventional diet and exercise programs.
Findings released in a prominent health publication demonstrates that while obese people often shed substantial amounts of their body weight while on the medication, the weight is regained at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using these treatments need to be aware of the potential of quick rebound weight gain when the therapy ends," warns lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to starting weight in about a year and a half.
Comparing Approaches
The study, which reviewed dozens of trials involving thousands of patients, contrasted the effects of the injectable medications with other pills.
Researchers note that individuals who shed pounds through diet and exercise typically experience a slower weight regain—around 100 grams monthly—once they finish.
Explaining the Rapid Rebound
Doctors suggest the way of the injections accounts for the amplified regain.
The injections mimic a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production might result in the body to generate a reduced amount of its endogenous hormone, and could diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' means appetite is uncontrolled, making binge eating much more probable."
An Ongoing Disease?
Health authorities recommend the injections for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
Many experts contend that, due to the likelihood of relapse, the treatment is often ongoing.
This view is supported by pharmaceutical companies, who say that the results "underscore the chronic nature of obesity," similar to managing conditions like high blood pressure.
User Testimonies
Users who have stopped the medication describe a sudden resurgence of cravings.
"It felt as if something activating and I was suddenly starving," described a patient.
This challenge is exacerbated if individuals have not adopted lasting dietary or behavioural modifications during treatment.
Growing Adoption
Figures indicate that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.
- Adoption is greater among women than males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than the NHS.
Finally, clinicians stress that while these medications are potent agents for shedding pounds, they are not a magic fix and lasting health benefits relies on integrated lifestyle support.
