A recent study suggests that people who come off popular GLP-1 drugs like Mounjaro or Wegovy may regain shed pounds far faster than those who halt traditional lifestyle plans.
Research printed in a prominent health publication demonstrates that while overweight people frequently drop a large proportion of their total mass while on the medication, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"Users purchasing such medications need to be cognizant of the danger of fast weight regain when the treatment concludes," stated expert Dr. Susan Jebb.
Such speed of recovery suggests a return to original weight within about one and a half years.
The research, which looked at dozens of studies involving thousands of patients, compared the effects of these new drugs with conventional dieting.
Researchers point out that individuals who shed pounds through dieting generally have a more gradual weight regain—perhaps 100 grams monthly—once they finish.
Nutrition scientists propose the way of the jabs explains the amplified weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of GLP-1 levels far above than normal may cause the body to generate a reduced amount of its own natural hormone, and could lessen sensitivity to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this medication leads to hunger is no longer kept in check, making overeating a significant risk."
Health authorities advise the injections for people with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians say that, due to the likelihood of relapse, the treatment might need to be life-long.
This perspective is reinforced by pharmaceutical companies, who note that the findings "underscore the long-term nature of excess weight," akin to managing diseases like diabetes.
People who have come off the medication describe a sudden return of appetite.
"It felt as if a switch that goes on and you become extremely hungry," recalled a patient.
This difficulty is worsened if patients have not adopted permanent dietary or behavioural modifications during therapy.
Recent estimates indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire continuing to grow.
Ultimately, experts caution that while the jabs are powerful tools for shedding pounds, they are not a standalone solution and long-term success relies on ongoing lifestyle changes.
