Fresh analysis indicates that people who come off new weight-loss injections like Wegovy and Mounjaro may regain reduced body mass far faster than those who stop conventional lifestyle programs.
Findings released in a leading health publication demonstrates that while obese people frequently drop substantial amounts of their total mass while using the jabs, the mass returns at an average rate of nearly a kilo each month once they quit.
"People using these drugs should be aware of the risk of rapid rebound weight gain when the medication ends," cautioned lead investigator Dr. Susan Jebb.
This pace of regain implies a return to pre-treatment weight within about 18 months.
Comparing Therapies
The study, which looked at 37 of trials involving thousands of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Researchers note that people who lose weight through lifestyle changes alone typically see a slower weight regain—approximately 0.1 kg a month—after stopping.
Understanding the Quick Rebound
Nutrition scientists suggest the way of the jabs explains the amplified regain.
These medications imitate a body's own chemical called GLP-1, which helps regulate appetite.
"Sustained high doses of the hormone concentrations far above than normal might result in the system to produce less of its own natural GLP-1, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' results in appetite is unsuppressed, making excessive eating far more likely."
A Chronic Disease?
Health authorities suggest the jabs for people with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Professionals say that, considering the high risk of relapse, the therapy might need to be life-long.
This perspective is supported by drug manufacturers, who say that the findings "underscore the long-term character of obesity," comparing it to managing diseases like diabetes.
Patient Experiences
Users who have discontinued the jabs explain a sudden resurgence of appetite.
"It felt as if something activating and you're instantly ravenous," recalled one woman.
The struggle is exacerbated if patients have not established permanent lifestyle or habit changes during therapy.
Growing Use
Figures show that millions of adults in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Use is higher among females compared to males.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than public health services.
In conclusion, experts emphasize that while these medications are effective tools for shedding pounds, they are not a permanent fix and long-term success relies on ongoing behavioural management.
