Fresh analysis indicates that people who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight much more quickly than those who halt traditional lifestyle programs.
Research printed in a leading health publication shows that while overweight individuals often shed substantial amounts of their total mass while using the jabs, the mass returns at an estimated rate of nearly a kilo each month after stopping.
"Individuals purchasing these medications should be cognizant of the danger of rapid rebound weight gain when the medication ends," cautioned lead investigator Dr. Susan Jebb.
This pace of regain suggests a reversion to starting mass within about one and a half years.
Comparing Treatments
The research, which reviewed dozens of trials involving thousands of participants, compared the results of these new drugs with older methods.
Scientists emphasize that people who shed pounds through lifestyle changes alone generally experience a slower creep back—perhaps 0.1 kg a month—after stopping.
Explaining the Quick Regain
Experts suggest the way of the jabs explains the accelerated regain.
GLP-1 drugs mimic a body's own chemical called GLP-1, which controls feelings of fullness.
"Long-term administration of GLP-1 levels several times higher than the body's typical production could lead to the system to produce less of its own natural GLP-1, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' leads to appetite is no longer kept in check, making binge eating far more likely."
A Lifelong Condition?
Medical guidelines recommend the injections for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Professionals argue that, considering the likelihood of weight regain, the treatment might need to be long-term.
This opinion is echoed by pharmaceutical companies, who state that the results "emphasize the chronic nature of obesity," comparing it to managing diseases like diabetes.
Patient Testimonies
Users who have come off the jabs report a intense resurgence of hunger.
"I experienced a trigger activating and you're instantly starving," recalled an individual.
This challenge is compounded if users have not developed sustainable lifestyle or habit modifications during treatment.
Significant Use
Survey data indicate that millions of adults in the UK have used these injections in the past year, with demand being substantial.
- Adoption is higher among females compared to males.
- The 40s and 50s age group shows the highest level of interest.
- Many access the medications through private prescriptions rather than the NHS.
Ultimately, experts stress that while these medications are potent agents for shedding pounds, they are not a permanent cure and long-term success hinges on integrated lifestyle changes.
