A recent study suggests that patients who stop using popular slimming jabs like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who end traditional lifestyle plans.
Published data in a prominent medical journal shows that while overweight people can lose substantial amounts of their body weight while undergoing treatment, the mass is regained at an estimated rate of 0.8 kg per month after stopping.
"People purchasing these drugs should be aware of the potential of quick rebound weight gain when the treatment ends," cautioned expert Dr. Susan Jebb.
Such speed of regain implies a return to original weight within about one and a half years.
Comparing Therapies
The research, which examined 37 of studies involving thousands of participants, contrasted the effects of GLP-1 agonists with other pills.
Scientists point out that people who shed pounds through lifestyle changes alone generally have a more gradual creep back—perhaps 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Doctors propose the way of the drugs is key to understanding the amplified rebound.
These medications mimic a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production could lead to the body to produce less of its endogenous GLP-1, and could reduce sensitivity to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement means appetite is unsuppressed, making binge eating far more likely."
A Chronic Disease?
Medical guidelines suggest the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
Many experts contend that, considering the likelihood of weight regain, the therapy is often long-term.
This opinion is echoed by drug manufacturers, who state that the results "highlight the persistent nature of obesity," similar to managing diseases like hypertension.
User Accounts
People who have discontinued the jabs explain a sudden resurgence of appetite.
"It felt as if a trigger flipping and you're instantly starving," said one woman.
The struggle is exacerbated if individuals have not developed lasting dietary or behavioural modifications during treatment.
Growing Use
Survey data show that millions of people in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Use is more common among females compared to men.
- The middle-aged age group shows the highest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
Finally, clinicians caution that while the jabs are powerful agents for weight loss, they are not a permanent fix and lasting health benefits relies on ongoing behavioural support.
