Fresh analysis suggests that patients who discontinue blockbuster GLP-1 drugs like Wegovy and Mounjaro tend to recover lost weight at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Published data in a prominent health publication shows that while overweight people often shed about a fifth of their total mass while using the jabs, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using these drugs need to be informed of the danger of quick rebound weight gain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
This pace of regain suggests a return to original mass within about 18 months.
Weighing Therapies
The research, which reviewed 37 of studies involving over 9,000 of participants, contrasted the outcomes of these new drugs with conventional dieting.
Scientists point out that people who lose weight through lifestyle changes alone generally have a slower creep back—around 100 grams monthly—once they finish.
The Reason for the Quick Rebound
Nutrition scientists suggest the mode of action of the jabs is key to understanding the heightened regain.
These medications imitate a natural hormone called GLP-1, which moderates feelings of fullness.
"Long-term administration of the hormone levels far above than normal could lead to the system to generate a reduced amount of its endogenous hormone, and could reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' results in appetite is no longer kept in check, making overeating a significant risk."
A Chronic Issue?
Medical guidelines suggest the jabs for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
Many experts say that, given the high risk of relapse, the treatment might need to be life-long.
This view is echoed by drug manufacturers, who note that the findings "emphasize the chronic character of obesity," comparing it to managing diseases like diabetes.
User Testimonies
Users who have stopped the jabs describe a powerful resurgence of appetite.
"It felt as if a trigger activating and you become extremely hungry," described one woman.
The struggle is exacerbated if users have not developed permanent dietary or behavioural modifications during treatment.
Widespread Adoption
Figures indicate that millions of adults in the UK have tried these injections in the past year, with interest remaining high.
- Use is more common among females compared to men.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the medications through private prescriptions rather than the NHS.
In conclusion, researchers stress that while the jabs are potent tools for shedding pounds, they are not a standalone fix and long-term success relies on integrated lifestyle changes.
