A recent study reveals that individuals who stop using popular weight-loss injections like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who end traditional lifestyle plans.
Research printed in a prominent medical journal points out that while overweight individuals can lose about a fifth of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month after stopping.
"People buying these medications must be aware of the potential of fast weight regain when the treatment ends," cautioned expert Dr. Susan Jebb.
This pace of regain means a return to starting mass in about one and a half years.
Comparing Treatments
The research, which examined dozens of studies involving thousands of patients, compared the effects of GLP-1 agonists with other pills.
Scientists emphasize that individuals who lose weight through diet and exercise usually see a less rapid weight regain—approximately 100 grams monthly—after stopping.
Explaining the Rapid Rebound
Doctors suggest the way of the jabs is key to understanding the accelerated weight return.
These medications imitate a natural hormone called GLP-1, which moderates appetite.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production could lead to the system to produce less of its own natural GLP-1, and could diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition researcher.
"Stopping of this GLP-1 'fix' results in appetite is uncontrolled, making binge eating far more likely."
A Lifelong Issue?
Medical guidelines advise the injections for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Professionals say that, due to the high risk of relapse, the therapy might need to be life-long.
This perspective is reinforced by pharmaceutical companies, who say that the results "underscore the long-term nature of excess weight," akin to managing conditions like hypertension.
Patient Accounts
People who have stopped the medication describe a intense return of cravings.
"It felt as if something that goes on and you become starving," said one woman.
The struggle is exacerbated if users have not established lasting lifestyle or habit changes during therapy.
Significant Adoption
Figures show that millions of people in the UK have tried weight-loss jabs in the last 12 months, with demand remaining high.
- Use is more common among women compared to men.
- The 40s and 50s age group shows the highest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
Finally, researchers stress that while GLP-1 drugs are effective agents for weight loss, they are not a permanent cure and maintained weight loss hinges on integrated lifestyle support.
