A recent study indicates that people who come off popular GLP-1 drugs like Wegovy and Mounjaro can put back on lost weight much more quickly than those who halt traditional lifestyle plans.
Research printed in a prominent health publication demonstrates that while overweight people frequently drop substantial amounts of their total mass while on the medication, the mass returns at an estimated rate of 0.8 kg per month after stopping.
"Users buying these medications should be aware of the potential of rapid rebound weight gain when the medication concludes," stated lead investigator Dr. Susan Jebb.
This pace of regain implies a return to starting weight in about 18 months.
Weighing Treatments
The study, which examined 37 of studies involving thousands of participants, contrasted the effects of GLP-1 agonists with other pills.
Researchers point out that people who lose weight through dieting usually experience a slower creep back—approximately 0.1 kg a month—once they finish.
Understanding the Rapid Rebound
Doctors believe the mode of action of the injections explains the heightened rebound.
The injections imitate a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Long-term administration of the hormone concentrations far above than the body's typical production might result in the system to produce less of its endogenous GLP-1, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement leads to hunger is uncontrolled, making overeating much more probable."
A Chronic Condition?
Medical guidelines suggest the injections for people with obesity-related health risks, alongside recommended diet and exercise modifications.
Many experts say that, given the significant potential of relapse, the treatment should be considered long-term.
This view is reinforced by pharmaceutical companies, who note that the results "emphasize the chronic nature of excess weight," comparing it to managing conditions like diabetes.
User Experiences
Users who have stopped the jabs report a powerful resurgence of cravings.
"It felt as if a trigger flipping and you become ravenous," said one woman.
This challenge is worsened if individuals have not developed lasting lifestyle or habit modifications during treatment.
Growing Use
Recent estimates indicate that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with demand being substantial.
- Use is higher among women than males.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, clinicians emphasize that while GLP-1 drugs are effective tools for weight loss, they are not a magic solution and maintained weight loss relies on ongoing lifestyle management.
