Fresh analysis suggests that people who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds far faster than those who stop traditional lifestyle plans.
Research printed in a prominent medical journal points out that while overweight people can lose substantial amounts of their body weight while using the jabs, the weight comes back at an average rate of nearly a kilo each month once they quit.
"Individuals purchasing these medications need to be aware of the potential of quick weight regain when the medication is stopped," stated researcher Dr. Susan Jebb.
Such speed of regain suggests a return to original weight in about a year and a half.
Analyzing Therapies
The study, which examined 37 of trials involving thousands of participants, contrasted the outcomes of the injectable medications with conventional dieting.
The team note that individuals who shed pounds through dieting typically see a slower weight regain—around 0.1 kg a month—after stopping.
Understanding the Rapid Regain
Nutrition scientists suggest the mode of action of the drugs is key to understanding the accelerated rebound.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than normal could lead to the body to produce less of its endogenous GLP-1, and could reduce responsiveness to its actions," noted Dr. Adam Collins, a nutrition expert.
"Stopping of this GLP-1 'fix' means hunger is unsuppressed, making excessive eating much more probable."
A Lifelong Issue?
The NHS advise the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Many experts contend that, considering the high risk of weight regain, the therapy should be considered ongoing.
This opinion is reinforced by drug manufacturers, who note that the findings "underscore the chronic character of obesity," similar to managing conditions like hypertension.
Patient Experiences
Users who have come off the jabs describe a sudden resurgence of hunger.
"It was like something activating and you become starving," said an individual.
This challenge is compounded if patients have not established sustainable dietary or behavioural changes during treatment.
Widespread Interest
Figures indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Adoption is more common among women than men.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, clinicians caution that while the jabs are effective agents for weight loss, they are not a permanent cure and long-term success hinges on integrated lifestyle management.
