New research suggests that people who come off blockbuster weight-loss injections like Mounjaro or Wegovy can put back on shed pounds at a significantly accelerated pace than those who stop traditional lifestyle regimens.
Published data in a prominent health publication shows that while overweight people often shed substantial amounts of their body weight while using the jabs, the mass returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals buying such drugs must be cognizant of the danger of rapid weight regain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
Such speed of recovery means a reversion to starting weight within about a year and a half.
Weighing Treatments
The analysis, which reviewed 37 of studies involving over 9,000 of patients, compared the outcomes of the injectable medications with other pills.
The team note that people who shed pounds through dieting usually have a slower creep back—perhaps 0.1 kg a month—after stopping.
Understanding the Rapid Regain
Doctors suggest the way of the drugs is key to understanding the amplified rebound.
GLP-1 drugs imitate a natural hormone called GLP-1, which helps regulate appetite.
"Long-term administration of GLP-1 levels several times higher than normal may cause the system to generate a reduced amount of its endogenous GLP-1, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement results in appetite is uncontrolled, making binge eating much more probable."
An Ongoing Disease?
The NHS recommend the injections for individuals with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians argue that, considering the likelihood of weight regain, the therapy might need to be life-long.
This view is supported by pharmaceutical companies, who state that the results "underscore the chronic character of obesity," comparing it to managing conditions like high blood pressure.
Patient Experiences
Users who have come off the jabs report a intense return of cravings.
"It was like something activating and you're instantly ravenous," said a patient.
The struggle is compounded if individuals have not adopted lasting lifestyle or habit modifications during therapy.
Widespread Interest
Survey data indicate that millions of people in the UK have used these injections in the last 12 months, with interest continuing to grow.
- Adoption is greater among females than males.
- The 40s and 50s age group shows the greatest level of interest.
- Many obtain the medications through private healthcare rather than public health services.
Ultimately, experts stress that while these medications are potent tools for weight loss, they are not a permanent fix and lasting health benefits relies on combined lifestyle support.
