Fresh analysis reveals that people who discontinue new weight-loss injections like Mounjaro or Wegovy can put back on reduced body mass much more quickly than those who stop conventional lifestyle plans.
Findings released in a leading health publication shows that while overweight individuals frequently drop a large proportion of their body weight while on the medication, the weight comes back at an estimated rate of 0.8 kg per month after stopping.
"Users using such treatments must be aware of the danger of fast rebound weight gain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
This pace of regain means a reversion to pre-treatment mass within about one and a half years.
Analyzing Approaches
The research, which reviewed dozens of studies involving thousands of patients, contrasted the results of these new drugs with other pills.
Scientists point out that people who lose weight through lifestyle changes alone generally have a less rapid creep back—around 0.1 kg a month—once they finish.
Understanding the Fast Rebound
Experts propose the way of the injections is key to understanding the amplified weight return.
These medications copy a body's own chemical called GLP-1, which moderates appetite.
"Artificially providing the hormone levels far above than normal could lead to the system to generate a reduced amount of its endogenous GLP-1, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication results in appetite is no longer kept in check, making excessive eating a significant risk."
An Ongoing Issue?
Health authorities suggest the injections for people with obesity-related health risks, accompanied by recommended diet and exercise modifications.
Professionals say that, considering the likelihood of weight regain, the treatment is often long-term.
This opinion is supported by pharmaceutical companies, who note that the findings "emphasize the chronic nature of obesity," similar to managing conditions like hypertension.
Patient Testimonies
People who have stopped the medication report a sudden return of appetite.
"I experienced a trigger flipping and you're instantly starving," recalled an individual.
This difficulty is worsened if patients have not established sustainable lifestyle or habit changes during therapy.
Significant Use
Survey data suggest that a significant number of people in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is higher among women than males.
- The middle-aged demographic shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than the NHS.
Ultimately, researchers stress that while the jabs are powerful tools for shedding pounds, they are not a permanent cure and long-term success relies on ongoing lifestyle support.
