Fresh analysis reveals that patients who discontinue popular slimming jabs like Mounjaro or Wegovy can put back on shed pounds much more quickly than those who stop traditional diet and exercise plans.
Findings released in a major medical journal points out that while overweight individuals can lose a large proportion of their total mass while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"Users purchasing such medications should be aware of the potential of fast weight regain when the therapy is stopped," stated lead investigator Dr. Susan Jebb.
This pace of recovery suggests a reversion to original mass in about one and a half years.
Analyzing Therapies
The study, which reviewed dozens of trials involving thousands of patients, compared the effects of GLP-1 agonists with other pills.
Researchers emphasize that people who shed pounds through diet and exercise usually see a more gradual weight regain—approximately 0.1 kg a month—after stopping.
Understanding the Fast Regain
Nutrition scientists suggest the mode of action of the drugs is key to understanding the heightened weight return.
These medications copy a natural hormone called GLP-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production could lead to the system to produce less of its endogenous hormone, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this medication results in appetite is unsuppressed, making binge eating far more likely."
An Ongoing Condition?
Health authorities suggest the jabs for people with obesity-related medical conditions, accompanied by recommended lifestyle changes.
A number of clinicians say that, considering the high risk of weight regain, the treatment is often life-long.
This opinion is echoed by pharmaceutical companies, who say that the findings "highlight the long-term nature of obesity," comparing it to managing conditions like hypertension.
Patient Accounts
Users who have discontinued the medication describe a intense return of cravings.
"It felt as if a switch flipping and I was suddenly ravenous," described an individual.
This challenge is compounded if individuals have not adopted permanent lifestyle or habit modifications during treatment.
Widespread Interest
Recent estimates suggest that millions of people in the UK have tried these injections in the past year, with interest continuing to grow.
- Use is greater among women compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, experts caution that while these medications are potent agents for shedding pounds, they are not a magic cure and maintained weight loss likely depends on integrated behavioural support.
