A recent study indicates that people who come off popular GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass far faster than those who halt traditional lifestyle regimens.
Research printed in a leading health publication shows that while overweight individuals can lose substantial amounts of their total mass while using the jabs, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"Users using these treatments must be aware of the danger of fast weight regain when the medication concludes," stated expert Dr. Susan Jebb.
This pace of recovery suggests a return to starting weight in about 18 months.
Comparing Therapies
The research, which reviewed 37 of studies involving over 9,000 of participants, compared the outcomes of the injectable medications with older methods.
Scientists emphasize that individuals who lose weight through lifestyle changes alone usually experience a more gradual creep back—perhaps 100 grams monthly—once they finish.
The Reason for the Rapid Regain
Nutrition scientists propose the mechanism of the injections explains the amplified rebound.
These medications imitate a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone concentrations several times higher than the body's typical production might result in the system to generate a reduced amount of its endogenous GLP-1, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' leads to appetite is unsuppressed, making binge eating much more probable."
An Ongoing Disease?
Health authorities advise the injections for people with obesity-related health risks, alongside recommended diet and exercise modifications.
Professionals say that, given the significant potential of weight regain, the therapy should be considered ongoing.
This opinion is supported by pharmaceutical companies, who say that the results "underscore the long-term nature of obesity," comparing it to managing conditions like high blood pressure.
User Testimonies
People who have discontinued the medication describe a intense return of appetite.
"I experienced a trigger activating and you're instantly extremely hungry," recalled one woman.
The struggle is worsened if users have not adopted permanent lifestyle or habit changes during treatment.
Significant Interest
Figures suggest that a significant number of people in the UK have tried these injections in the past year, with desire continuing to grow.
- Adoption is higher among females than men.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, experts emphasize that while GLP-1 drugs are effective agents for shedding pounds, they are not a standalone cure and maintained weight loss likely depends on integrated behavioural management.
