A recent study suggests that people who come off popular slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass much more quickly than those who halt traditional diet and exercise regimens.
Published data in a prominent health publication points out that while obese people frequently drop substantial amounts of their total mass while on the medication, the weight returns at an estimated rate of 0.8 kg per month once they quit.
"Individuals buying such medications must be cognizant of the danger of fast rebound weight gain when the medication concludes," cautioned researcher Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment mass within about 18 months.
Comparing Therapies
The analysis, which examined 37 of trials involving thousands of patients, compared the outcomes of these new drugs with conventional dieting.
The team note that individuals who lose weight through diet and exercise usually have a slower creep back—around 100 grams monthly—post-intervention.
The Reason for the Rapid Regain
Experts suggest the mechanism of the jabs explains the heightened rebound.
These medications mimic a body's own chemical called GLP-1, which controls hunger.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production may cause the body to generate a reduced amount of its endogenous hormone, and may also diminish responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this medication leads to hunger is uncontrolled, making overeating a significant risk."
A Chronic Condition?
Medical guidelines advise the jabs for people with obesity-related health risks, alongside prescribed lifestyle changes.
Professionals argue that, due to the significant potential of weight regain, the therapy is often life-long.
This view is echoed by drug manufacturers, who say that the findings "emphasize the persistent character of excess weight," akin to managing conditions like diabetes.
User Testimonies
People who have discontinued the jabs describe a intense resurgence of appetite.
"It felt as if a trigger activating and you're instantly extremely hungry," recalled a patient.
This difficulty is compounded if individuals have not developed lasting lifestyle or habit changes during treatment.
Significant Interest
Survey data show that millions of adults in the UK have tried these injections in the past year, with interest being substantial.
- Use is greater among women than males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion access the drugs through private healthcare rather than the NHS.
Ultimately, researchers emphasize that while GLP-1 drugs are powerful agents for shedding pounds, they are not a magic cure and long-term success hinges on combined lifestyle changes.
