Fresh analysis reveals that people who come off popular GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass much more quickly than those who stop conventional lifestyle plans.
Findings released in a leading health publication shows that while overweight people often shed a large proportion of their body weight while on the medication, the mass comes back at an estimated rate of 0.8 kg per month once they quit.
"Users using these medications must be informed of the risk of rapid weight regain when the medication is stopped," stated researcher Dr. Susan Jebb.
Such speed of recovery suggests a reversion to pre-treatment weight within about a year and a half.
Analyzing Approaches
The study, which examined 37 of trials involving over 9,000 of patients, compared the effects of these new drugs with other pills.
Researchers point out that people who lose weight through diet and exercise generally have a more gradual creep back—around 0.1 kg a month—after stopping.
The Reason for the Rapid Regain
Doctors suggest the mechanism of the injections explains the amplified weight return.
These medications mimic a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing GLP-1 concentrations far above than normal might result in the body to generate a reduced amount of its own natural hormone, and could lessen responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' means appetite is uncontrolled, making binge eating a significant risk."
A Chronic Issue?
Medical guidelines advise the jabs for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Professionals contend that, due to the high risk of weight regain, the therapy should be considered ongoing.
This view is supported by drug manufacturers, who say that the results "emphasize the chronic character of excess weight," akin to managing conditions like high blood pressure.
Patient Experiences
Users who have come off the jabs describe a powerful return of hunger.
"It felt as if a trigger flipping and you become extremely hungry," said one woman.
The struggle is compounded if users have not adopted lasting lifestyle or habit modifications during treatment.
Significant Use
Survey data suggest that a significant number of adults in the UK have tried these injections in the past year, with demand being substantial.
- Adoption is higher among women than men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Ultimately, experts emphasize that while the jabs are effective tools for weight loss, they are not a magic cure and maintained weight loss relies on combined lifestyle management.
