A recent study indicates that patients who discontinue blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover lost weight much more quickly than those who halt traditional diet and exercise plans.
Findings released in a leading health publication points out that while overweight individuals frequently drop a large proportion of their body weight while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month once they quit.
"Individuals using these drugs should be cognizant of the potential of quick rebound weight gain when the therapy ends," warns researcher Dr. Susan Jebb.
Such speed of regain suggests a reversion to original mass in about a year and a half.
Analyzing Treatments
The research, which looked at 37 of trials involving thousands of participants, contrasted the results of these new drugs with older methods.
Scientists point out that people who shed pounds through lifestyle changes alone usually experience a more gradual creep back—approximately 0.1 kg a month—once they finish.
The Reason for the Fast Regain
Nutrition scientists suggest the mode of action of the drugs accounts for the amplified rebound.
These medications imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its own natural GLP-1, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication results in appetite is uncontrolled, making overeating a significant risk."
An Ongoing Disease?
Health authorities suggest the injections for people with obesity-related health risks, accompanied by recommended lifestyle changes.
Many experts argue that, due to the significant potential of relapse, the treatment might need to be ongoing.
This opinion is supported by pharmaceutical companies, who note that the findings "emphasize the chronic character of excess weight," akin to managing diseases like high blood pressure.
User Testimonies
Users who have discontinued the jabs explain a powerful resurgence of hunger.
"It was like something activating and I was suddenly ravenous," recalled a patient.
The struggle is compounded if patients have not developed lasting lifestyle or habit modifications during therapy.
Widespread Use
Survey data suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire being substantial.
- Use is higher among women than males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the medications through private healthcare rather than the NHS.
Finally, clinicians emphasize that while these medications are potent agents for shedding pounds, they are not a permanent fix and long-term success relies on integrated lifestyle changes.
