Summary

Christmas is a time of celebration, when friends and family gather to enjoy meals together. However, many of us overindulge, which leaves us feeling tired, bloated, and guilty. What actually happens to our bodies when we overeat, drink more, and swap fibre for sugar? And is there a way to enjoy the season’s pleasures without starting January full of regret? In this episode, ZOE’s Head Nutritionist, Dr Federica Amati, joins Jonathan to explore how festive food traditions shape our health and how to navigate them without guilt or restriction. Dr Federica shares practical suggestions for gut-friendly food swaps, festive traditions worth reviving, and the one ingredient she always includes on her own Christmas table. This episode is full of helpful advice on how to care for your body in a season that often asks us to do the opposite.
