New research indicates that people who stop using popular GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight far faster than those who end traditional lifestyle programs.
Research printed in a leading health publication shows that while obese individuals frequently drop substantial amounts of their total mass while using the jabs, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Users purchasing such drugs must be informed of the potential of quick rebound weight gain when the medication is stopped," stated researcher Dr. Susan Jebb.
That rate of regain implies a reversion to starting weight within about a year and a half.
Analyzing Treatments
The research, which reviewed 37 of studies involving thousands of patients, contrasted the results of the injectable medications with older methods.
Scientists emphasize that people who shed pounds through lifestyle changes alone usually experience a slower creep back—around 100 grams monthly—after stopping.
Explaining the Quick Rebound
Doctors suggest the mode of action of the drugs is key to understanding the heightened regain.
The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of the hormone concentrations several times higher than the body's typical production could lead to the body to produce less of its own natural hormone, and could lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication results in appetite is no longer kept in check, making binge eating far more likely."
An Ongoing Issue?
Medical guidelines suggest the injections for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.
Professionals contend that, given the likelihood of weight regain, the treatment is often life-long.
This perspective is supported by drug manufacturers, who state that the results "underscore the persistent nature of obesity," comparing it to managing diseases like hypertension.
User Testimonies
Users who have discontinued the medication report a intense resurgence of hunger.
"It felt as if a switch that goes on and you become starving," described one woman.
The struggle is exacerbated if users have not established lasting lifestyle or habit modifications during treatment.
Significant Interest
Figures show that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is greater among females compared to males.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, clinicians caution that while GLP-1 drugs are powerful tools for shedding pounds, they are not a standalone solution and maintained weight loss likely depends on integrated behavioural changes.
