A recent study suggests that people who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy tend to recover reduced body mass at a significantly accelerated pace than those who end traditional diet and exercise plans.
Published data in a major health publication shows that while obese people often shed about a fifth of their body weight while using the jabs, the weight returns at an estimated rate of nearly a kilo each month after stopping.
"Users buying such medications must be informed of the risk of rapid rebound weight gain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
Such speed of recovery suggests a return to starting mass in about 18 months.
Analyzing Therapies
The analysis, which looked at 37 of studies involving over 9,000 of patients, compared the outcomes of the injectable medications with older methods.
Researchers point out that people who shed pounds through diet and exercise typically have a more gradual creep back—approximately 100 grams monthly—once they finish.
Understanding the Quick Rebound
Experts propose the mode of action of the jabs accounts for the amplified rebound.
The injections mimic a body's own chemical called GLP-1, which controls feelings of fullness.
"Artificially providing the hormone levels far above than the body's typical production could lead to the body to produce less of its endogenous hormone, and may also lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Stopping of this GLP-1 'fix' results in hunger is uncontrolled, making excessive eating a significant risk."
A Lifelong Disease?
Medical guidelines advise the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians argue that, due to the likelihood of relapse, the therapy might need to be life-long.
This perspective is echoed by drug manufacturers, who state that the findings "underscore the persistent character of excess weight," akin to managing diseases like diabetes.
User Accounts
Users who have come off the medication describe a sudden return of hunger.
"It felt as if a trigger activating and you become starving," recalled one woman.
The struggle is exacerbated if users have not developed lasting dietary or behavioural modifications during treatment.
Significant Adoption
Survey data suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Use is greater among females than males.
- The middle-aged demographic shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, experts stress that while these medications are effective tools for weight loss, they are not a permanent cure and maintained weight loss likely depends on integrated behavioural support.
