New research indicates that individuals who discontinue new weight-loss injections like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who stop conventional diet and exercise plans.
Research printed in a leading medical journal points out that while overweight people frequently drop a large proportion of their body weight while on the medication, the mass returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Users using such medications must be aware of the danger of fast rebound weight gain when the treatment concludes," warns researcher Dr. Susan Jebb.
Such speed of recovery means a return to pre-treatment weight in about 18 months.
Analyzing Therapies
The analysis, which examined 37 of studies involving over 9,000 of participants, compared the results of GLP-1 agonists with other pills.
Researchers emphasize that individuals who shed pounds through diet and exercise typically have a slower creep back—perhaps 100 grams monthly—after stopping.
The Reason for the Rapid Regain
Experts propose the way of the injections is key to understanding the heightened rebound.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone levels far above than the body's typical production might result in the system to produce less of its endogenous GLP-1, and could reduce responsiveness to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication means appetite is no longer kept in check, making binge eating a significant risk."
A Chronic Issue?
The NHS suggest the injections for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
A number of clinicians contend that, considering the significant potential of weight regain, the treatment is often life-long.
This opinion is supported by pharmaceutical companies, who state that the findings "highlight the chronic nature of excess weight," similar to managing diseases like diabetes.
User Testimonies
Individuals who have come off the medication explain a intense resurgence of cravings.
"It was like a switch flipping and I was suddenly starving," described an individual.
This challenge is worsened if patients have not adopted permanent dietary or behavioural modifications during treatment.
Growing Adoption
Survey data suggest that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.
- Adoption is greater among women than men.
- The middle-aged age group shows the highest level of interest.
- Many access the medications through private healthcare rather than public health services.
Ultimately, clinicians caution that while GLP-1 drugs are effective agents for shedding pounds, they are not a standalone cure and lasting health benefits hinges on ongoing lifestyle changes.
