New research suggests that people who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight much more quickly than those who stop conventional diet and exercise regimens.
Research printed in a major health publication points out that while overweight people frequently drop substantial amounts of their body weight while using the jabs, the mass is regained at an average rate of 0.8 kg per month once they quit.
"Individuals using these medications should be aware of the danger of quick weight regain when the treatment ends," cautioned expert Dr. Susan Jebb.
That rate of regain means a reversion to original mass within about a year and a half.
Weighing Approaches
The analysis, which looked at dozens of studies involving thousands of participants, contrasted the effects of GLP-1 agonists with other pills.
Scientists point out that individuals who lose weight through diet and exercise generally experience a more gradual creep back—approximately 100 grams monthly—once they finish.
The Reason for the Quick Regain
Nutrition scientists suggest the mechanism of the drugs explains the heightened regain.
GLP-1 drugs imitate a natural hormone called GLP-1, which moderates hunger.
"Artificially providing the hormone concentrations far above than normal might result in the body to produce less of its own natural GLP-1, and may also reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' means hunger is uncontrolled, making excessive eating a significant risk."
A Chronic Condition?
Medical guidelines suggest the jabs for individuals with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians argue that, due to the likelihood of relapse, the treatment is often life-long.
This perspective is supported by drug manufacturers, who state that the findings "underscore the chronic character of excess weight," comparing it to managing diseases like high blood pressure.
Patient Accounts
Individuals who have come off the medication report a powerful return of hunger.
"It was like something activating and you become starving," described an individual.
The struggle is exacerbated if patients have not developed permanent lifestyle or habit modifications during therapy.
Significant Use
Recent estimates suggest that a significant number of people in the UK have tried weight-loss jabs in the past year, with demand being substantial.
- Use is higher among females than males.
- The middle-aged demographic shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while these medications are potent tools for weight loss, they are not a magic fix and long-term success relies on integrated behavioural management.
