A recent study reveals 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 diet and exercise plans.
Research printed in a major health publication shows that while obese individuals frequently drop substantial amounts of their total mass while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Users purchasing these treatments need to be aware of the risk of quick weight regain when the medication ends," warns researcher Dr. Susan Jebb.
That rate of regain implies a return to pre-treatment weight within about 18 months.
Comparing Therapies
The study, which looked at dozens of studies involving thousands of patients, contrasted the results of the injectable medications with older methods.
The team point out that individuals who shed pounds through diet and exercise typically have a less rapid creep back—perhaps 0.1 kg a month—post-intervention.
Understanding the Rapid Regain
Doctors suggest the way of the drugs accounts for the amplified regain.
These medications imitate a body's own chemical called GLP-1, which helps regulate appetite.
"Long-term administration of GLP-1 levels far above than the body's typical production may cause the system to generate a reduced amount of its endogenous GLP-1, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' means appetite is unsuppressed, making overeating much more probable."
An Ongoing Condition?
Health authorities suggest the injections for people with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians say that, given the high risk of relapse, the treatment might need to be long-term.
This perspective is supported by pharmaceutical companies, who state that the findings "emphasize the persistent nature of excess weight," akin to managing conditions like diabetes.
User Experiences
People who have discontinued the medication describe a powerful resurgence of cravings.
"It felt as if a trigger flipping and you become extremely hungry," recalled a patient.
The struggle is worsened if patients have not established sustainable lifestyle or habit changes during treatment.
Significant Interest
Survey data indicate that a significant number of adults 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 highest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, researchers caution that while the jabs are effective tools for weight loss, they are not a permanent fix and maintained weight loss hinges on combined behavioural support.
