A recent study indicates that individuals who stop using blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover shed pounds far faster than those who halt traditional diet and exercise regimens.
Research printed in a leading medical journal shows that while overweight individuals can lose substantial amounts of their total mass while on the medication, the mass is regained at an estimated rate of 0.8 kg per month after stopping.
"Users using these drugs must be aware of the risk of fast rebound weight gain when the treatment ends," warns lead investigator Dr. Susan Jebb.
That rate of regain means a reversion to original mass in about 18 months.
Weighing Therapies
The research, which looked at dozens of studies involving thousands of patients, compared the outcomes of the injectable medications with older methods.
Scientists emphasize that people who shed pounds through dieting usually see a more gradual weight regain—around 100 grams monthly—once they finish.
Understanding the Quick Rebound
Doctors suggest the mechanism of the jabs explains the heightened rebound.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which controls appetite.
"Artificially providing the hormone concentrations several times higher than the body's typical production could lead to the body to generate a reduced amount of its own natural GLP-1, and may also lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement results in appetite is uncontrolled, making binge eating far more likely."
A Chronic Condition?
Health authorities recommend the jabs for people with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Professionals say that, due to the likelihood of weight regain, the therapy is often long-term.
This opinion is supported by pharmaceutical companies, who say that the results "emphasize the persistent character of excess weight," similar to managing diseases like high blood pressure.
User Experiences
Users who have stopped the jabs explain a intense resurgence of cravings.
"It felt as if something that goes on and you're instantly ravenous," said an individual.
The struggle is exacerbated if patients have not developed lasting lifestyle or habit changes during therapy.
Significant Adoption
Survey data suggest that millions of adults in the UK have used these injections in the last 12 months, with desire being substantial.
- Adoption is higher among females than men.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
Ultimately, clinicians emphasize that while GLP-1 drugs are effective agents for shedding pounds, they are not a standalone cure and lasting health benefits relies on ongoing behavioural support.
