New research indicates that individuals who come off popular GLP-1 drugs like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who halt traditional diet and exercise regimens.
Findings released in a major medical journal points out that while overweight people often shed about a fifth of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month after stopping.
"People purchasing these treatments should be aware of the danger of quick weight regain when the therapy concludes," warns researcher Dr. Susan Jebb.
This pace of recovery means a return to starting mass in about 18 months.
Comparing Treatments
The study, which reviewed 37 of trials involving over 9,000 of participants, contrasted the outcomes of the injectable medications with conventional dieting.
Researchers point out that people who lose weight through lifestyle changes alone generally experience a less rapid weight regain—perhaps 100 grams monthly—post-intervention.
Explaining the Rapid Regain
Nutrition scientists suggest the mechanism of the drugs explains the amplified regain.
The injections imitate a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Artificially providing the hormone levels far above than normal could lead to the body to generate a reduced amount of its own natural hormone, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' means appetite is uncontrolled, making excessive eating much more probable."
A Chronic Condition?
Health authorities suggest the jabs for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
A number of clinicians contend that, given the significant potential of relapse, the treatment should be considered long-term.
This view is echoed by pharmaceutical companies, who state that the results "emphasize the persistent nature of obesity," comparing it to managing conditions like diabetes.
User Testimonies
Users who have discontinued the jabs describe a sudden return of hunger.
"I experienced a trigger that goes on and I was suddenly starving," described an individual.
This difficulty is worsened if users have not established permanent lifestyle or habit modifications during therapy.
Significant Use
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Adoption is greater among females compared to men.
- The middle-aged age group shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
Finally, experts emphasize that while these medications are powerful agents for shedding pounds, they are not a magic cure and long-term success likely depends on integrated lifestyle changes.
