Fresh analysis indicates that patients who come off new weight-loss injections like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who end conventional diet and exercise regimens.
Published data in a prominent health publication points out that while overweight individuals can lose substantial amounts of their body weight while on the medication, the mass returns at an average rate of 0.8 kg per month upon discontinuation.
"Users purchasing such medications need to be informed of the potential of rapid weight regain when the medication concludes," stated lead investigator Dr. Susan Jebb.
Such speed of regain suggests a return to starting mass in about one and a half years.
Weighing Treatments
The research, which looked at dozens of studies involving thousands of participants, compared the results of GLP-1 agonists with conventional dieting.
Scientists emphasize that people who lose weight through diet and exercise generally see a less rapid creep back—around 100 grams monthly—once they finish.
Explaining the Quick Rebound
Experts believe the mechanism of the drugs is key to understanding the accelerated weight return.
These medications imitate a body's own chemical called GLP-1, which controls hunger.
"Artificially providing the hormone concentrations far above than the body's typical production could lead to the system to generate a reduced amount of its endogenous GLP-1, and could lessen responsiveness to its actions," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement leads to appetite is unsuppressed, making binge eating much more probable."
A Lifelong Disease?
Health authorities recommend the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Many experts contend that, given the significant potential of weight regain, the treatment might need to be life-long.
This opinion is echoed by drug manufacturers, who note that the results "emphasize the persistent character of excess weight," comparing it to managing diseases like high blood pressure.
User Experiences
People who have stopped the jabs report a intense resurgence of appetite.
"It was like a trigger flipping and you become starving," described an individual.
This difficulty is exacerbated if users have not established sustainable dietary or behavioural changes during treatment.
Growing Use
Figures suggest that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Use is greater among females than males.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, experts emphasize that while the jabs are effective tools for shedding pounds, they are not a permanent solution and maintained weight loss likely depends on integrated lifestyle management.
