A recent study reveals that patients who stop using blockbuster GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight much more quickly than those who stop traditional diet and exercise plans.
Research printed in a major health publication demonstrates that while obese people often shed a large proportion of their body weight while using the jabs, the weight returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing such medications should be cognizant of the potential of quick rebound weight gain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
That rate of regain suggests a return to pre-treatment mass within about a year and a half.
Analyzing Therapies
The analysis, which looked at 37 of studies involving thousands of participants, contrasted the outcomes of the injectable medications with other pills.
The team note that people who lose weight through dieting generally experience a less rapid creep back—around 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Nutrition scientists suggest the mechanism of the drugs accounts for the heightened rebound.
These medications mimic a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Artificially providing the hormone concentrations far above than the body's typical production may cause the body to generate a reduced amount of its endogenous hormone, and could reduce responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication leads to hunger is unsuppressed, making excessive eating far more likely."
A Chronic Condition?
Medical guidelines suggest the jabs for people with obesity-related health risks, alongside recommended lifestyle changes.
Many experts contend that, considering the significant potential of weight regain, the treatment might need to be long-term.
This opinion is supported by drug manufacturers, who state that the findings "highlight the chronic character of excess weight," similar to managing conditions like diabetes.
User Testimonies
People who have discontinued the medication report a powerful return of hunger.
"It was like a switch flipping and I was suddenly extremely hungry," said an individual.
This challenge is compounded if individuals have not established permanent lifestyle or habit modifications during therapy.
Growing Use
Recent estimates indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Adoption is higher among females than males.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the medications through private healthcare rather than public health services.
In conclusion, clinicians caution that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic cure and long-term success relies on combined lifestyle support.
