A recent study indicates that people who discontinue blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain reduced body mass far faster than those who stop traditional lifestyle programs.
Research printed in a major medical journal shows that while overweight people can lose a large proportion of their body weight while using the jabs, the mass is regained at an average rate of nearly a kilo each month after stopping.
"People buying such medications must be cognizant of the risk of fast rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.
Such speed of recovery suggests a reversion to starting weight in about 18 months.
Comparing Treatments
The analysis, which looked at 37 of studies involving thousands of participants, compared the results of GLP-1 agonists with other pills.
Scientists emphasize that individuals who lose weight through diet and exercise generally experience a less rapid weight regain—approximately 100 grams monthly—post-intervention.
Understanding the Quick Regain
Doctors propose the mechanism of the jabs explains the heightened weight return.
These medications mimic a natural hormone called GLP-1, which moderates hunger.
"Sustained high doses of GLP-1 concentrations several times higher than normal could lead to the system to produce less of its endogenous GLP-1, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement means appetite is uncontrolled, making overeating far more likely."
A Lifelong Disease?
Medical guidelines recommend the injections for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, given the likelihood of weight regain, the therapy should be considered long-term.
This opinion is echoed by pharmaceutical companies, who say that the results "underscore the chronic character of obesity," comparing it to managing diseases like high blood pressure.
Patient Accounts
People who have discontinued the medication describe a intense resurgence of hunger.
"It felt as if a trigger that goes on and you're instantly extremely hungry," described a patient.
The struggle is compounded if individuals have not adopted sustainable dietary or behavioural modifications during treatment.
Growing Interest
Figures show that millions of people in the UK have tried these injections in the past year, with desire continuing to grow.
- Adoption is higher among women than men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, experts caution that while GLP-1 drugs are effective tools for shedding pounds, they are not a permanent cure and lasting health benefits relies on combined behavioural changes.
