Fresh analysis indicates that people who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who halt conventional lifestyle programs.
Published data in a leading health publication demonstrates that while overweight people can lose a large proportion of their body weight while on the medication, the mass comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"People buying such medications must be informed of the risk of quick weight regain when the treatment is stopped," stated expert Dr. Susan Jebb.
Such speed of recovery implies a return to pre-treatment mass in about a year and a half.
Weighing Therapies
The research, which reviewed 37 of studies involving thousands of participants, compared the outcomes of these new drugs with other pills.
The team note that people who lose weight through dieting generally experience a less rapid weight regain—perhaps 100 grams monthly—after stopping.
Explaining the Quick Rebound
Nutrition scientists believe the way of the jabs explains the amplified regain.
These medications mimic a natural hormone called GLP-1, which moderates appetite.
"Artificially providing the hormone concentrations far above than normal might result in the body to generate a reduced amount of its own natural GLP-1, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement leads to appetite is no longer kept in check, making binge eating far more likely."
An Ongoing Disease?
The NHS recommend the injections for people with obesity-related health risks, alongside prescribed lifestyle changes.
A number of clinicians say that, due to the significant potential of weight regain, the treatment should be considered long-term.
This opinion is supported by drug manufacturers, who note that the results "highlight the long-term nature of obesity," comparing it to managing diseases like diabetes.
Patient Testimonies
Users who have come off the jabs report a sudden resurgence of appetite.
"It was like something that goes on and I was suddenly starving," recalled an individual.
This challenge is exacerbated if patients have not developed permanent lifestyle or habit modifications during treatment.
Widespread Adoption
Recent estimates suggest that a significant number of adults in the UK have used these injections in the past year, with interest being substantial.
- Adoption is more common among women than men.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the drugs through private prescriptions rather than public health services.
Ultimately, experts emphasize that while these medications are powerful tools for weight loss, they are not a magic fix and lasting health benefits hinges on integrated lifestyle management.
