Fresh analysis suggests that people who discontinue popular slimming jabs like Mounjaro or Wegovy tend to recover lost weight far faster than those who stop conventional lifestyle plans.
Research printed in a leading medical journal points out that while obese individuals often shed about a fifth of their total mass while undergoing treatment, the weight returns at an estimated rate of 0.8 kg per month once they quit.
"Individuals using these medications need to be aware of the danger of rapid rebound weight gain when the therapy concludes," cautioned lead investigator Dr. Susan Jebb.
This pace of recovery means a reversion to original mass within about a year and a half.
Comparing Approaches
The analysis, which reviewed 37 of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Scientists note that individuals who lose weight through lifestyle changes alone typically see a less rapid creep back—perhaps 100 grams monthly—after stopping.
Explaining the Rapid Regain
Nutrition scientists propose the mode of action of the jabs is key to understanding the amplified weight return.
These medications copy a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone levels far above than the body's typical production might result in the body to generate a reduced amount of its endogenous hormone, and could reduce sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication results in hunger is no longer kept in check, making overeating a significant risk."
A Lifelong Condition?
Health authorities advise the injections for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Many experts argue that, due to the significant potential of relapse, the therapy should be considered ongoing.
This view is reinforced by drug manufacturers, who state that the results "underscore the persistent character of obesity," akin to managing diseases like hypertension.
User Experiences
Individuals who have stopped the medication report a powerful return of appetite.
"I experienced a trigger flipping and you're instantly extremely hungry," recalled one woman.
This difficulty is compounded if users have not developed sustainable lifestyle or habit changes during treatment.
Widespread Adoption
Recent estimates indicate that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.
- Adoption is more common among women than men.
- The middle-aged age group shows the highest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, experts emphasize that while GLP-1 drugs are powerful agents for shedding pounds, they are not a permanent fix and lasting health benefits likely depends on integrated lifestyle management.
