Fresh analysis reveals that patients who stop using new weight-loss injections like Mounjaro or Wegovy tend to recover reduced body mass far faster than those who end traditional lifestyle programs.
Published data in a leading health publication shows that while overweight people often shed about a fifth of their body weight while on the medication, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"Individuals using these medications must be informed of the risk of rapid rebound weight gain when the therapy concludes," cautioned expert Dr. Susan Jebb.
This pace of regain implies a return to starting weight within about one and a half years.
Analyzing Approaches
The study, which reviewed dozens of studies involving thousands of participants, compared the effects of the injectable medications with other pills.
Researchers point out that people who lose weight through dieting usually see a less rapid weight regain—perhaps 100 grams monthly—after stopping.
Understanding the Rapid Regain
Doctors believe the way of the jabs accounts for the accelerated regain.
These medications copy a natural hormone called GLP-1, which moderates appetite.
"Artificially providing GLP-1 concentrations far above than normal could lead to the body to produce less of its endogenous GLP-1, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement leads to appetite is uncontrolled, making binge eating a significant risk."
A Chronic Disease?
Medical guidelines advise the jabs for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
Many experts say that, given the significant potential of weight regain, the treatment might need to be ongoing.
This opinion is supported by pharmaceutical companies, who say that the results "underscore the long-term nature of excess weight," comparing it to managing diseases like diabetes.
Patient Testimonies
People who have discontinued the jabs describe a powerful return of appetite.
"It felt as if a trigger flipping and you're instantly extremely hungry," recalled an individual.
This challenge is worsened if individuals have not established lasting dietary or behavioural modifications during therapy.
Widespread Interest
Survey data show that a significant number of people in the UK have used these injections in the last 12 months, with interest remaining high.
- Adoption is greater among females than men.
- The 40s and 50s demographic shows the greatest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers caution that while GLP-1 drugs are powerful tools for weight loss, they are not a permanent fix and long-term success likely depends on integrated lifestyle changes.
