Fresh analysis suggests that people who discontinue popular GLP-1 drugs like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who halt conventional lifestyle programs.
Published data in a major medical journal shows that while overweight individuals can lose a large proportion of their body weight while using the jabs, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"People buying these drugs need to be aware of the risk of rapid weight regain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to starting mass within about 18 months.
Weighing Approaches
The analysis, which examined dozens of trials involving thousands of patients, contrasted the results of GLP-1 agonists with other pills.
Scientists point out that individuals who lose weight through diet and exercise usually see a more gradual weight regain—approximately 100 grams monthly—once they finish.
Understanding the Fast Rebound
Experts believe the mechanism of the drugs explains the accelerated weight return.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production might result in the system to generate a reduced amount of its endogenous hormone, and could lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication means hunger is uncontrolled, making excessive eating far more likely."
An Ongoing Disease?
The NHS advise the jabs for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals argue that, due to the significant potential of weight regain, the treatment is often long-term.
This opinion is supported by drug manufacturers, who note that the results "emphasize the chronic nature of obesity," comparing it to managing conditions like hypertension.
User Testimonies
Users who have come off the jabs describe a sudden return of hunger.
"It was like a switch that goes on and you're instantly ravenous," recalled a patient.
This challenge is exacerbated if users have not adopted lasting lifestyle or habit changes during treatment.
Significant Interest
Figures show that a significant number of adults in the UK have tried these injections in the last 12 months, with demand remaining high.
- Use is more common among females compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers caution that while the jabs are potent tools for shedding pounds, they are not a standalone fix and maintained weight loss likely depends on combined behavioural management.
