Fresh analysis suggests that people who come off new slimming jabs like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who stop traditional lifestyle regimens.
Research printed in a major medical journal shows that while obese individuals frequently drop substantial amounts of their total mass while on the medication, the mass comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"People purchasing such treatments should be aware of the risk of rapid rebound weight gain when the medication is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of regain suggests a reversion to original mass in about 18 months.
Weighing Treatments
The research, which examined 37 of studies involving thousands of participants, contrasted the effects of the injectable medications with older methods.
Researchers note that people who lose weight through dieting typically experience a less rapid creep back—perhaps 0.1 kg a month—after stopping.
Explaining the Fast Regain
Experts believe the mode of action of the jabs accounts for the amplified weight return.
These medications copy a natural hormone called glucagon-like peptide-1, which controls appetite.
"Long-term administration of the hormone levels far above than normal might result in the system to generate a reduced amount of its endogenous GLP-1, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement means appetite is no longer kept in check, making excessive eating far more likely."
A Chronic Disease?
Health authorities advise the injections for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Many experts argue that, due to the significant potential of relapse, the therapy is often ongoing.
This perspective is echoed by pharmaceutical companies, who say that the results "underscore the persistent character of obesity," similar to managing diseases like diabetes.
User Experiences
People who have discontinued the medication report a powerful resurgence of appetite.
"It was like something that goes on and I was suddenly ravenous," described a patient.
The struggle is compounded if individuals have not developed permanent lifestyle or habit changes during therapy.
Widespread Adoption
Recent estimates suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Adoption is higher among women than males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, clinicians emphasize that while GLP-1 drugs are powerful agents for shedding pounds, they are not a standalone solution and maintained weight loss relies on ongoing lifestyle management.
