A recent study reveals that patients who discontinue popular slimming jabs like Mounjaro or Wegovy may regain reduced body mass at a significantly accelerated pace than those who end traditional lifestyle plans.
Published data in a prominent medical journal points out that while overweight people often shed substantial amounts of their body weight while undergoing treatment, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"Individuals using these drugs must be informed of the potential of rapid weight regain when the medication concludes," stated expert Dr. Susan Jebb.
This pace of recovery implies a return to original weight in about a year and a half.
Analyzing Therapies
The study, which examined dozens of trials involving thousands of participants, compared the effects of GLP-1 agonists with older methods.
Scientists note that people who lose weight through lifestyle changes alone usually see a more gradual creep back—around 0.1 kg a month—post-intervention.
Explaining the Fast Regain
Experts believe the way of the jabs is key to understanding the accelerated regain.
The injections mimic a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of the hormone levels far above than normal may cause the body to produce less of its endogenous GLP-1, and could lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement leads to hunger is no longer kept in check, making overeating much more probable."
A Lifelong Issue?
Medical guidelines suggest the injections for people with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
Professionals say that, given the high risk of relapse, the therapy should be considered life-long.
This perspective is supported by drug manufacturers, who state that the findings "emphasize the long-term nature of excess weight," akin to managing conditions like high blood pressure.
User Experiences
Users who have discontinued the medication describe a intense resurgence of hunger.
"It was like something flipping and I was suddenly extremely hungry," said a patient.
This difficulty is exacerbated if individuals have not developed sustainable dietary or behavioural changes during therapy.
Significant Use
Survey data suggest that millions of adults in the UK have used weight-loss jabs in the last 12 months, with desire remaining high.
- Use is higher among women compared to males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers stress that while these medications are potent agents for weight loss, they are not a magic fix and long-term success hinges on ongoing lifestyle support.
