A recent study reveals that people who stop using new slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass at a significantly accelerated pace than those who stop conventional diet and exercise regimens.
Published data in a major health publication demonstrates that while overweight individuals can lose about a fifth of their total mass while undergoing treatment, the mass returns at an estimated rate of nearly a kilo each month after stopping.
"Users using these treatments need to be cognizant of the danger of quick rebound weight gain when the medication concludes," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery implies a reversion to original weight within about one and a half years.
Comparing Therapies
The study, which looked at dozens of studies involving thousands of patients, compared the effects of these new drugs with other pills.
Scientists emphasize that individuals who lose weight through diet and exercise typically experience a slower creep back—approximately 0.1 kg a month—post-intervention.
The Reason for the Fast Rebound
Doctors propose the mechanism of the injections is key to understanding the amplified regain.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Long-term administration of the hormone concentrations far above than normal might result in the body to produce less of its own natural hormone, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement means hunger is uncontrolled, making binge eating much more probable."
A Lifelong Issue?
The NHS suggest the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
A number of clinicians argue that, considering the high risk of relapse, the treatment is often long-term.
This opinion is reinforced by pharmaceutical companies, who say that the results "underscore the persistent character of obesity," similar to managing diseases like hypertension.
Patient Experiences
Individuals who have come off the jabs explain a sudden return of appetite.
"It felt as if a trigger that goes on and you're instantly starving," described one woman.
The struggle is compounded if users have not developed permanent lifestyle or habit changes during treatment.
Significant Adoption
Survey data show that millions of people in the UK have used these injections in the past year, with demand remaining high.
- Adoption is more common among females compared to males.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while the jabs are powerful tools for weight loss, they are not a magic cure and lasting health benefits likely depends on ongoing lifestyle management.
