A recent study suggests that people who discontinue new GLP-1 drugs like Mounjaro or Wegovy can put back on reduced body mass far faster than those who end conventional diet and exercise plans.
Published data in a prominent medical journal demonstrates that while obese people can lose substantial amounts of their total mass while on the medication, the weight is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Users purchasing such medications need to be aware of the potential of quick weight regain when the medication is stopped," stated lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to starting mass within about a year and a half.
Analyzing Therapies
The analysis, which examined dozens of studies involving over 9,000 of participants, compared the effects of the injectable medications with other pills.
Researchers note that people who shed pounds through diet and exercise generally have a slower weight regain—perhaps 0.1 kg a month—once they finish.
The Reason for the Rapid Regain
Nutrition scientists propose the mode of action of the injections accounts for the heightened regain.
The injections imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production may cause the body to generate a reduced amount of its endogenous hormone, and may also diminish sensitivity to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' means appetite is no longer kept in check, making excessive eating much more probable."
An Ongoing Disease?
The NHS advise the jabs for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals contend that, given the significant potential of weight regain, the therapy might need to be ongoing.
This perspective is echoed by drug manufacturers, who say that the findings "underscore the long-term nature of excess weight," akin to managing diseases like high blood pressure.
User Testimonies
Individuals who have come off the jabs report a powerful return of appetite.
"I experienced something that goes on and you become extremely hungry," said an individual.
This difficulty is compounded if patients have not adopted permanent lifestyle or habit modifications during treatment.
Significant Interest
Recent estimates indicate that millions of adults in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is higher among women compared to men.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, experts emphasize that while GLP-1 drugs are effective agents for weight loss, they are not a standalone fix and lasting health benefits hinges on combined behavioural changes.
