A recent study reveals that individuals who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy can put back on shed pounds far faster than those who end conventional lifestyle regimens.
Published data in a leading medical journal points out that while overweight individuals can lose substantial amounts of their body weight while on the medication, the mass returns at an estimated rate of nearly a kilo each month once they quit.
"People buying these medications need to be informed of the danger of rapid rebound weight gain when the medication concludes," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to starting weight within about a year and a half.
Analyzing Approaches
The analysis, which looked at 37 of studies involving thousands of patients, compared the outcomes of the injectable medications with other pills.
The team point out that people who shed pounds through diet and exercise typically see a more gradual weight regain—approximately 0.1 kg a month—once they finish.
Explaining the Fast Rebound
Nutrition scientists suggest the mechanism of the injections is key to understanding the heightened weight return.
The injections mimic a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone concentrations far above than normal might result in the body to produce less of its endogenous hormone, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement leads to appetite is unsuppressed, making binge eating a significant risk."
A Lifelong Disease?
The NHS suggest the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of relapse, the treatment might need to be long-term.
This opinion is echoed by drug manufacturers, who note that the results "underscore the persistent character of obesity," akin to managing diseases like diabetes.
User Testimonies
People who have stopped the jabs explain a intense return of hunger.
"It felt as if a trigger activating and you're instantly ravenous," described one woman.
This challenge is compounded if individuals have not developed lasting dietary or behavioural modifications during therapy.
Widespread Adoption
Recent estimates show that millions of people in the UK have used these injections in the last 12 months, with demand continuing to grow.
- Use is higher among females than males.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians caution that while these medications are effective tools for shedding pounds, they are not a standalone fix and long-term success relies on ongoing lifestyle support.
