Stopping weight loss jabs can lead to rapid weight regain in one year, study suggests | Science, Climate & Tech News
People on obesity jabs will regain the majority of the weight they lose within a year of stopping the drugs, a new study suggests. Researchers at the University of Cambridge found that after stopping the jabs for 52 weeks, on average people had regained 60% of the weight they lost. They warned that if the regained weight is mainly fat, patients could “be worse off than before” they started the jabs. How do the drugs work? Weight loss jabs are a class of drugs known as GLP-1 receptor agonists, which work by mimicking the hormone GLP-1 to regulate blood sugar and insulin levels. Originally developed as a treatment for type 2 diabetes, certain types, such as semaglutide (Wegovy) and tirzepatide (Mounjaro), are approved for use on the NHS to help tackle obesity. The jabs could also be used to prevent and treat addiction to alcohol, cigarettes and drugs like cannabis, cocaine, nicotine and opioids, a second study involving more than 600,000 US veterans with type 2 diabetes suggests. Experts believe the way the GLP-1 receptor …
