Can you boost energy, improve focus and lift your mood in just a few days, just by changing what you eat? 

In this episode, Professor Tim Spector and ZOE’s Head Nutritionist, Dr Federica Amati, break down the simple nutrition changes that help beat fatigue and shift how you feel. 

They speak to Lucy and Sarah, who put ZOE to the test and changed only their nutrition for six weeks. At the start, they were held back by brain fog, poor sleep, and constant tiredness. Could a six-week nutritional reset really move the needle? 

This episode shows what happened in real life as they explore why many people feel tired or flat, even when tests look “normal”. The episode explains why your gut microbiome matters, how you can feel better within days, and why consistency beats perfection.

You will also hear the simple changes they made. Bigger breakfasts. More plant diversity. Easy food swaps. Small habits that fit into real life.

If you feel tired but your tests say you’re “fine”, what would you change first? And if you felt better in days, would you keep going for six weeks?
