New research reveals that individuals who discontinue popular slimming jabs like Mounjaro or Wegovy tend to recover shed pounds far faster than those who stop traditional diet and exercise plans.
Research printed in a leading medical journal demonstrates that while overweight people often shed a large proportion of their total mass while on the medication, the weight is regained at an average rate of 0.8 kg per month once they quit.
"Individuals purchasing these drugs need to be informed of the risk of quick weight regain when the medication is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain means a reversion to starting weight within about a year and a half.
Analyzing Treatments
The analysis, which reviewed dozens of trials involving thousands of patients, compared the effects of these new drugs with conventional dieting.
Researchers point out that people who shed pounds through dieting typically experience a more gradual creep back—around 0.1 kg a month—after stopping.
Explaining the Fast Regain
Experts believe the mechanism of the drugs is key to understanding the amplified weight return.
The injections imitate a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of the hormone concentrations far above than the body's typical production could lead to the body to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' leads to appetite is no longer kept in check, making overeating a significant risk."
An Ongoing Disease?
The NHS advise the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians say that, given the significant potential of weight regain, the treatment is often long-term.
This perspective is echoed by pharmaceutical companies, who state that the results "highlight the persistent character of excess weight," comparing it to managing conditions like diabetes.
Patient Testimonies
People who have come off the medication describe a intense resurgence of cravings.
"I experienced a switch flipping and I was suddenly starving," described a patient.
This challenge is compounded if users have not developed permanent lifestyle or habit changes during treatment.
Significant Adoption
Figures show that millions of people in the UK have used these injections in the past year, with desire continuing to grow.
- Adoption is higher among women compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the medications through private prescriptions rather than public health services.
In conclusion, experts emphasize that while the jabs are powerful agents for shedding pounds, they are not a standalone cure and long-term success likely depends on ongoing lifestyle changes.
