A recent study reveals that individuals who come off new GLP-1 drugs like Mounjaro or Wegovy can put back on shed pounds much more quickly than those who end conventional diet and exercise plans.
Findings released in a leading medical journal shows that while obese people often shed about a fifth of their total mass while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"People purchasing such drugs should be cognizant of the risk of fast weight regain when the treatment ends," cautioned researcher Dr. Susan Jebb.
This pace of recovery suggests a return to pre-treatment weight within about one and a half years.
Comparing Approaches
The research, which looked at 37 of studies involving thousands of participants, contrasted the effects of the injectable medications with older methods.
Researchers emphasize that people who lose weight through lifestyle changes alone generally have a less rapid creep back—approximately 100 grams monthly—once they finish.
Understanding the Quick Regain
Doctors propose the mode of action of the jabs is key to understanding the amplified weight return.
The injections mimic a body's own chemical called GLP-1, which helps regulate hunger.
"Artificially providing GLP-1 levels several times higher than normal may cause the system to produce less of its own natural GLP-1, and could reduce sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' leads to hunger is unsuppressed, making excessive eating a significant risk."
A Lifelong Disease?
The NHS advise the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
Professionals argue that, given the likelihood of weight regain, the treatment should be considered long-term.
This opinion is supported by drug manufacturers, who note that the findings "underscore the persistent character of obesity," akin to managing diseases like high blood pressure.
User Testimonies
Individuals who have discontinued the medication describe a sudden return of hunger.
"It was like a switch that goes on and you're instantly starving," described a patient.
The struggle is worsened if patients have not developed permanent lifestyle or habit modifications during therapy.
Significant Use
Figures suggest that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is greater among females than males.
- The 40s and 50s age group shows the greatest usage rates.
- Many access the drugs through private healthcare rather than the NHS.
Ultimately, researchers caution that while these medications are effective tools for shedding pounds, they are not a magic cure and long-term success hinges on integrated lifestyle management.
