The food landscape has undergone a dramatic shift over the years, and the numbers tell a sobering story. A study in The Lancet found that childhood and adolescent obesity rates worldwide have risen nearly fourfold from 1990 to 2022, while adult obesity rates have more than doubled. At the same time, dramatic celebrity weight loss has been linked to Ozempic, an injectable drug containing semaglutide, originally developed to treat type 2 diabetes but now widely used off-label as a weight-loss aid.

In this episode of In Focus, we ask: Why is it becoming harder to lose weight? What role do our gut and brain play in shaping our relationship with food? And should drugs like Ozempic step in where lifestyle changes and willpower fall short?
