A recent study indicates that individuals who come off blockbuster slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass much more quickly than those who halt traditional lifestyle programs.
Findings released in a leading medical journal points out that while overweight individuals frequently drop substantial amounts of their total mass while using the jabs, the mass returns at an estimated rate of 0.8 kg per month once they quit.
"People using these treatments need to be informed of the potential of quick weight regain when the medication ends," warns researcher Dr. Susan Jebb.
That rate of regain suggests a reversion to pre-treatment mass within about one and a half years.
Weighing Therapies
The research, which looked at dozens of trials involving thousands of participants, compared the effects of the injectable medications with other pills.
Scientists note that people who shed pounds through diet and exercise generally have a more gradual creep back—perhaps 100 grams monthly—after stopping.
Understanding the Fast Rebound
Nutrition scientists believe the mode of action of the jabs explains the heightened weight return.
These medications mimic a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of GLP-1 levels far above than the body's typical production could lead to the body to generate a reduced amount of its endogenous GLP-1, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this GLP-1 'fix' results in appetite is uncontrolled, making excessive eating much more probable."
An Ongoing Issue?
Medical guidelines recommend the jabs for individuals with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Professionals contend that, due to the high risk of relapse, the therapy should be considered long-term.
This opinion is reinforced by pharmaceutical companies, who state that the results "emphasize the chronic character of obesity," akin to managing diseases like hypertension.
Patient Testimonies
Individuals who have stopped the medication explain a powerful resurgence of appetite.
"It felt as if a switch activating and I was suddenly extremely hungry," described a patient.
This challenge is worsened if users have not established permanent dietary or behavioural modifications during treatment.
Widespread Interest
Recent estimates indicate that a significant number of adults in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Use is more common among females than men.
- The middle-aged age group shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than public health services.
Ultimately, experts stress that while these medications are powerful tools for shedding pounds, they are not a permanent fix and long-term success hinges on integrated behavioural changes.
