10 new diet and healthy eating books that will completely change how you eat in 2026

It’s not about the what or when you eat, according to Dr Jason Fung, but the why.

His book, The Hunger Code, unveils the three forces that propel us to eat – physical hunger, emotional hunger, and social hunger – and lists the rules and tips to break yourself out of the cycle. The advice aims to work whether you’re starting from scratch, trying them after fasting, or giving them a go after weight loss meds, all designed to lead to sustainable, achievable weight loss that will last for life.
