Fresh analysis indicates that patients who stop using blockbuster slimming jabs like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who stop traditional diet and exercise programs.
Research printed in a major medical journal points out that while overweight individuals can lose a large proportion of their body weight while on the medication, the weight returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing such drugs must be aware of the danger of quick weight regain when the therapy is stopped," stated researcher Dr. Susan Jebb.
That rate of recovery suggests a return to starting weight within about 18 months.
Weighing Approaches
The research, which looked at dozens of trials involving thousands of patients, compared the results of the injectable medications with conventional dieting.
The team point out that people who lose weight through dieting typically experience a more gradual creep back—around 100 grams monthly—once they finish.
Understanding the Fast Regain
Doctors propose the mechanism of the drugs accounts for the heightened rebound.
These medications imitate a natural hormone called GLP-1, which helps regulate appetite.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production may cause the body to generate a reduced amount of its endogenous GLP-1, and could reduce sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' results in appetite is no longer kept in check, making binge eating a significant risk."
A Chronic Disease?
The NHS suggest the injections for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
Professionals argue that, given the likelihood of weight regain, the treatment should be considered life-long.
This opinion is reinforced by pharmaceutical companies, who note that the findings "underscore the persistent nature of excess weight," akin to managing conditions like high blood pressure.
User Accounts
Users who have come off the medication describe a intense return of appetite.
"It was like something activating and I was suddenly ravenous," said an individual.
This difficulty is exacerbated if patients have not established lasting lifestyle or habit changes during therapy.
Widespread Adoption
Recent estimates indicate that a significant number of adults in the UK have tried these injections in the past year, with desire remaining high.
- Use is more common among women compared to men.
- The middle-aged demographic shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while the jabs are powerful tools for weight loss, they are not a magic fix and lasting health benefits hinges on combined behavioural management.
