A recent study suggests that people who stop using popular GLP-1 drugs like Mounjaro or Wegovy tend to recover shed pounds at a significantly accelerated pace than those who stop traditional lifestyle plans.
Published data in a major medical journal points out that while overweight individuals often shed substantial amounts of their total mass while using the jabs, the mass returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Users buying these medications must be cognizant of the danger of rapid rebound weight gain when the therapy concludes," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment weight within about one and a half years.
Weighing Approaches
The analysis, which reviewed dozens of studies involving thousands of participants, compared the effects of the injectable medications with other pills.
Scientists emphasize that people who lose weight through lifestyle changes alone usually experience a slower creep back—approximately 100 grams monthly—after stopping.
Understanding the Quick Regain
Nutrition scientists propose the mechanism of the drugs is key to understanding the amplified rebound.
The injections imitate a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing GLP-1 concentrations far above than the body's typical production might result in the body to generate a reduced amount of its own natural GLP-1, and could reduce sensitivity to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement leads to hunger is no longer kept in check, making overeating a significant risk."
An Ongoing Condition?
Medical guidelines advise the jabs for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians contend that, considering the significant potential of relapse, the therapy should be considered ongoing.
This opinion is echoed by pharmaceutical companies, who state that the findings "underscore the long-term nature of excess weight," similar to managing conditions like high blood pressure.
User Experiences
Individuals who have discontinued the jabs describe a sudden return of appetite.
"It felt as if a trigger flipping and you become starving," said a patient.
This difficulty is compounded if users have not established permanent lifestyle or habit modifications during treatment.
Widespread Interest
Figures show that millions of adults in the UK have tried these injections in the past year, with desire being substantial.
- Use is greater among women than males.
- The middle-aged age group shows the highest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
Ultimately, experts stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a standalone fix and lasting health benefits relies on ongoing lifestyle changes.
