New research indicates that people who discontinue blockbuster slimming jabs like Mounjaro or Wegovy may regain lost weight at a significantly accelerated pace than those who stop traditional lifestyle programs.
Published data in a major health publication demonstrates that while overweight people frequently drop about a fifth of their body weight while on the medication, the mass is regained at an estimated rate of nearly a kilo each month once they quit.
"People using these medications need to be informed of the danger of rapid weight regain when the medication ends," stated expert Dr. Susan Jebb.
Such speed of recovery suggests a reversion to pre-treatment weight within about a year and a half.
Analyzing Therapies
The study, which reviewed 37 of studies involving over 9,000 of participants, contrasted the effects of GLP-1 agonists with conventional dieting.
Researchers point out that people who lose weight through diet and exercise typically see a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.
The Reason for the Quick Regain
Experts suggest the way of the jabs is key to understanding the accelerated rebound.
The injections copy a body's own chemical called GLP-1, which helps regulate hunger.
"Artificially providing the hormone concentrations far above than normal may cause the system to generate a reduced amount of its own natural hormone, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' means hunger is uncontrolled, making excessive eating far more likely."
An Ongoing Issue?
The NHS suggest the jabs for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Professionals say that, given the likelihood of weight regain, the treatment should be considered life-long.
This perspective is reinforced by drug manufacturers, who state that the results "underscore the long-term nature of excess weight," akin to managing diseases like hypertension.
Patient Experiences
Individuals who have come off the jabs describe a intense return of cravings.
"It felt as if a switch that goes on and you're instantly extremely hungry," described one woman.
The struggle is worsened if patients have not adopted permanent dietary or behavioural changes during therapy.
Significant Adoption
Figures show that a significant number of adults in the UK have tried weight-loss jabs in the past year, with desire continuing to grow.
- Adoption is higher among females compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- Many access the medications through private prescriptions rather than public health services.
In conclusion, clinicians stress that while these medications are powerful agents for weight loss, they are not a permanent cure and long-term success likely depends on integrated lifestyle changes.
