Fresh analysis reveals that people who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain shed pounds far faster than those who stop traditional lifestyle plans.
Findings released in a prominent health publication demonstrates that while overweight people can lose substantial amounts of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month after stopping.
"People purchasing these drugs must be informed of the risk of fast rebound weight gain when the therapy is stopped," cautioned lead investigator Dr. Susan Jebb.
That rate of recovery means a return to original mass in about 18 months.
Comparing Therapies
The research, which examined dozens of trials involving over 9,000 of patients, contrasted the outcomes of these new drugs with older methods.
The team point out that people who shed pounds through diet and exercise typically experience a more gradual creep back—around 0.1 kg a month—once they finish.
Understanding the Rapid Rebound
Doctors propose the mode of action of the jabs explains the heightened regain.
The injections imitate a body's own chemical called GLP-1, which moderates hunger.
"Sustained high doses of the hormone concentrations far above than the body's typical production might result in the system to produce less of its own natural GLP-1, and may also reduce responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement leads to hunger is uncontrolled, making binge eating far more likely."
An Ongoing Issue?
The NHS recommend the jabs for individuals with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians say that, considering the high risk of weight regain, the therapy might need to be life-long.
This perspective is reinforced by pharmaceutical companies, who state that the findings "emphasize the long-term nature of excess weight," akin to managing diseases like high blood pressure.
User Experiences
Individuals who have discontinued the medication report a powerful return of appetite.
"It was like a trigger that goes on and you become starving," described one woman.
The struggle is worsened if individuals have not adopted lasting lifestyle or habit modifications during treatment.
Widespread Adoption
Survey data indicate that millions of people in the UK have tried weight-loss jabs in the past year, with demand remaining high.
- Adoption is more common among women compared to men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, experts emphasize that while the jabs are potent agents for shedding pounds, they are not a standalone cure and maintained weight loss relies on combined behavioural changes.
