A recent study suggests that individuals who stop using new slimming jabs like Wegovy and Mounjaro may regain lost weight much more quickly than those who stop traditional lifestyle plans.
Research printed in a major medical journal demonstrates that while overweight individuals often shed a large proportion of their body weight while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"Users purchasing such medications must be aware of the danger of rapid rebound weight gain when the medication ends," stated lead investigator Dr. Susan Jebb.
That rate of recovery suggests a reversion to pre-treatment weight in about 18 months.
Comparing Approaches
The study, which examined dozens of trials involving over 9,000 of patients, compared the results of GLP-1 agonists with conventional dieting.
Scientists point out that individuals who lose weight through diet and exercise usually see a more gradual creep back—approximately 100 grams monthly—after stopping.
Understanding the Fast Rebound
Experts believe the mechanism of the jabs is key to understanding the amplified regain.
GLP-1 drugs mimic a body's own chemical called GLP-1, which helps regulate hunger.
"Artificially providing the hormone concentrations several times higher than the body's typical production might result in the system to generate a reduced amount of its own natural hormone, and may also diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication leads to appetite is unsuppressed, making overeating far more likely."
A Lifelong Condition?
Health authorities suggest the jabs for people with obesity-related health risks, accompanied by recommended diet and exercise modifications.
Many experts contend that, considering the likelihood of weight regain, the treatment should be considered life-long.
This opinion is supported by pharmaceutical companies, who say that the findings "underscore the chronic nature of excess weight," comparing it to managing diseases like diabetes.
User Testimonies
People who have discontinued the medication describe a intense resurgence of cravings.
"It felt as if a trigger activating and I was suddenly extremely hungry," said a patient.
The struggle is worsened if patients have not developed lasting dietary or behavioural modifications during therapy.
Significant Adoption
Survey data show that millions of adults in the UK have used these injections in the past year, with desire being substantial.
- Use is higher among females than males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, experts caution that while these medications are effective tools for shedding pounds, they are not a standalone solution and long-term success likely depends on ongoing lifestyle changes.
