A recent study suggests that people who come off blockbuster slimming jabs like semaglutide or tirzepatide may regain shed pounds much more quickly than those who halt traditional lifestyle programs.
Findings released in a prominent health publication shows that while overweight people frequently drop a large proportion of their body weight while undergoing treatment, the weight is regained at an estimated rate of 0.8 kg per month after stopping.
"Users buying these drugs should be informed of the risk of quick weight regain when the treatment concludes," stated lead investigator Dr. Susan Jebb.
That rate of regain implies a reversion to original mass within about a year and a half.
Comparing Therapies
The research, which reviewed 37 of studies involving thousands of patients, contrasted the results of the injectable medications with conventional dieting.
Scientists point out that individuals who lose weight through dieting usually have a less rapid weight regain—perhaps 0.1 kg a month—after stopping.
Understanding the Rapid Regain
Doctors suggest the way of the drugs accounts for the accelerated rebound.
These medications imitate a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production might result in the system to generate a reduced amount of its own natural hormone, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' results in appetite is uncontrolled, making excessive eating much more probable."
A Chronic Condition?
The NHS recommend the injections for individuals with obesity-related medical conditions, alongside prescribed lifestyle changes.
A number of clinicians argue that, due to the significant potential of relapse, the treatment should be considered ongoing.
This perspective is supported by pharmaceutical companies, who state that the findings "highlight the long-term character of excess weight," similar to managing conditions like hypertension.
Patient Experiences
People who have come off the jabs report a sudden resurgence of hunger.
"It felt as if a trigger flipping and you become ravenous," recalled an individual.
The struggle is compounded if users have not established permanent lifestyle or habit changes during treatment.
Widespread Use
Survey data suggest that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Adoption is more common among females than males.
- The middle-aged demographic shows the greatest usage rates.
- Many access the medications through private prescriptions rather than public health services.
Ultimately, researchers caution that while GLP-1 drugs are potent tools for shedding pounds, they are not a standalone cure and maintained weight loss hinges on integrated lifestyle management.
