Fresh analysis suggests that individuals who come off blockbuster slimming jabs like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who end traditional diet and exercise plans.
Published data in a major health publication points out that while obese individuals often shed a large proportion of their total mass while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month once they quit.
"Individuals purchasing such treatments must be cognizant of the risk of quick rebound weight gain when the medication concludes," cautioned researcher Dr. Susan Jebb.
Such speed of regain means a return to original mass in about a year and a half.
Weighing Treatments
The analysis, which looked at 37 of studies involving thousands of patients, contrasted the effects of these new drugs with other pills.
Scientists note that individuals who shed pounds through diet and exercise generally see a more gradual weight regain—perhaps 100 grams monthly—once they finish.
Explaining the Rapid Rebound
Nutrition scientists propose the mechanism of the injections is key to understanding the amplified weight return.
The injections imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of GLP-1 levels far above than normal may cause the system to generate a reduced amount of its endogenous hormone, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this medication means appetite is uncontrolled, making overeating much more probable."
An Ongoing Issue?
The NHS suggest the jabs for people with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Professionals say that, due to the likelihood of relapse, the therapy should be considered life-long.
This perspective is echoed by drug manufacturers, who say that the findings "highlight the long-term character of obesity," similar to managing diseases like hypertension.
Patient Testimonies
People who have discontinued the jabs describe a powerful return of cravings.
"It felt as if something that goes on and you're instantly extremely hungry," described a patient.
The struggle is worsened if individuals have not established sustainable dietary or behavioural modifications during therapy.
Growing Interest
Figures indicate that a significant number of people in the UK have tried these injections in the past year, with interest remaining high.
- Adoption is higher among women than males.
- The middle-aged age group shows the greatest level of interest.
- Many access the drugs through private healthcare rather than the NHS.
Ultimately, researchers caution that while the jabs are powerful agents for shedding pounds, they are not a permanent solution and lasting health benefits hinges on combined behavioural management.
