A recent study suggests that patients who come off blockbuster GLP-1 drugs like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who halt traditional diet and exercise programs.
Findings released in a major health publication demonstrates that while overweight individuals frequently drop about a fifth of their body weight while on the medication, the mass returns at an average rate of 0.8 kg per month once they quit.
"People purchasing these drugs must be aware of the danger of fast rebound weight gain when the treatment ends," stated lead investigator Dr. Susan Jebb.
This pace of regain suggests a return to original weight within about a year and a half.
Analyzing Therapies
The study, which examined dozens of trials involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Researchers emphasize that people who lose weight through dieting usually see a slower weight regain—around 0.1 kg a month—once they finish.
Understanding the Rapid Regain
Nutrition scientists propose the way of the injections accounts for the amplified weight return.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing the hormone levels far above than normal might result in the system to produce less of its own natural hormone, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication results in hunger is uncontrolled, making binge eating a significant risk."
A Lifelong Issue?
Health authorities advise the jabs for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Many experts say that, considering the significant potential of weight regain, the therapy is often ongoing.
This opinion is echoed by drug manufacturers, who note that the findings "emphasize the chronic character of excess weight," akin to managing conditions like diabetes.
Patient Accounts
Users who have come off the jabs describe a intense resurgence of hunger.
"It felt as if something activating and I was suddenly ravenous," described a patient.
This difficulty is worsened if individuals have not adopted lasting dietary or behavioural changes during treatment.
Widespread Use
Recent estimates show that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.
- Use is greater among females than males.
- The middle-aged demographic shows the highest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
Finally, researchers emphasize that while these medications are powerful agents for weight loss, they are not a magic fix and maintained weight loss likely depends on combined lifestyle management.
