Sliced Bread - Weight-loss Injections

Is it ok to stay on weight loss injections?

They have been nothing short of a pharmaceutical phenomenon. But for people like listener Lynn who've had huge success on weight loss drugs like Mounjaro, the question now arises about the implications of using them long-term. Could there be a 'maintenance' dose that would potentially allow for use over many years, or even a lifetime? And as scientists study the data, are other benefits emerging that go beyond just losing weight that could burnish their wonder-product reputation?

Presenter Greg Foot is joined in the studio by Lynn to hear her story and do a deep-dive into the science alongside Professor of Molecular Neuroendocrinology at the University of Cambridge, Giles Yeo.
