Fresh analysis suggests that individuals who come off popular GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who stop conventional diet and exercise regimens.
Research printed in a major health publication points out that while overweight individuals often shed about a fifth of their body weight while undergoing treatment, the weight is regained at an estimated rate of 0.8 kg per month after stopping.
"Users purchasing such treatments must be aware of the risk of quick rebound weight gain when the medication concludes," cautioned researcher Dr. Susan Jebb.
Such speed of regain means a reversion to pre-treatment mass within about one and a half years.
Analyzing Therapies
The research, which reviewed dozens of studies involving over 9,000 of patients, contrasted the results of GLP-1 agonists with other pills.
The team emphasize that people who shed pounds through dieting usually have a more gradual weight regain—approximately 100 grams monthly—once they finish.
Explaining the Quick Regain
Doctors believe the mode of action of the injections accounts for the heightened rebound.
These medications copy a natural hormone called GLP-1, which controls feelings of fullness.
"Artificially providing GLP-1 levels several times higher than the body's typical production may cause the body to generate a reduced amount of its own natural hormone, and could lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' results in hunger is no longer kept in check, making excessive eating a significant risk."
A Chronic Disease?
Medical guidelines suggest the jabs for people with weight-linked health risks, alongside prescribed diet and exercise modifications.
Many experts argue that, given the likelihood of weight regain, the therapy is often ongoing.
This perspective is reinforced by drug manufacturers, who note that the findings "emphasize the long-term nature of excess weight," akin to managing diseases like high blood pressure.
Patient Testimonies
People who have discontinued the jabs report a intense return of appetite.
"It was like a switch that goes on and you're instantly extremely hungry," recalled a patient.
This challenge is worsened if individuals have not established sustainable dietary or behavioural modifications during treatment.
Growing Interest
Recent estimates show that a significant number of people in the UK have tried weight-loss jabs in the past year, with demand remaining high.
- Adoption is greater among females compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, clinicians stress that while the jabs are potent agents for shedding pounds, they are not a permanent cure and long-term success relies on ongoing behavioural changes.
