Weight-loss jabs are the latest craze for shedding a few pounds. Their effect has been dramatic with drugs such as Ozempic and Wegovy (semaglutide) causing users to lose up to 15% of their body fat on average.
Semaglutide, which is a glucagon-like peptide 1 (GLP-1 receptor agonist drug), mimics the action of a natural gut hormone which is released after we eat.
