A recent study suggests that patients who stop using new weight-loss injections like Mounjaro or Wegovy can put back on reduced body mass far faster than those who halt traditional diet and exercise plans.
Published data in a prominent health publication shows that while overweight individuals frequently drop substantial amounts of their body weight while on the medication, the weight comes back at an estimated rate of 0.8 kg per month after stopping.
"People buying these drugs must be aware of the danger of quick rebound weight gain when the medication ends," cautioned expert Dr. Susan Jebb.
That rate of recovery suggests a reversion to original weight in about one and a half years.
Comparing Therapies
The research, which examined dozens of trials involving over 9,000 of participants, contrasted the effects of these new drugs with other pills.
Researchers note that individuals who shed pounds through lifestyle changes alone generally see a less rapid creep back—around 0.1 kg a month—after stopping.
Understanding the Quick Rebound
Nutrition scientists propose the mechanism of the injections explains the accelerated weight return.
These medications imitate a natural hormone called glucagon-like peptide-1, which controls hunger.
"Artificially providing GLP-1 concentrations far above than the body's typical production might result in the system to produce less of its endogenous GLP-1, and could reduce responsiveness to its effects," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this medication results in appetite is unsuppressed, making binge eating much more probable."
An Ongoing Issue?
Health authorities advise the jabs for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Professionals contend that, due to the significant potential of relapse, the therapy is often long-term.
This perspective is reinforced by drug manufacturers, who state that the findings "emphasize the persistent nature of obesity," comparing it to managing conditions like high blood pressure.
User Testimonies
People who have come off the jabs report a powerful resurgence of appetite.
"It was like a trigger flipping and you're instantly extremely hungry," said an individual.
This difficulty is worsened if individuals have not established sustainable lifestyle or habit changes during therapy.
Significant Interest
Recent estimates suggest that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with interest being substantial.
- Use is more common among females than men.
- The middle-aged age group shows the highest usage rates.
- Many access the drugs through private healthcare rather than public health services.
Finally, experts caution that while the jabs are effective agents for weight loss, they are not a magic solution and long-term success likely depends on ongoing lifestyle support.
