And of course, as soon as people stopped adhering to their rigours, they immediately started putting the weight back on. So when Ozempic and Mounjaro appeared on the scene, I raised a quizzical eyebrow. I had already resolved to ask the diabetes nurse what she thought about me going on a fat jab. I am starting my Mounjaro journey weighing exactly 18 stones (114kg). I’m starting with a low dose of 2.5mg of Mounjaro a week, rising to 5mg after the first month, and hopefully I won’t need to go above that.
