About the book

The Fiber Formula

“This book is a comprehensive guide for something I’ve been passionate about for over a decade: understanding the importance of fiber for our gut health – and how to eat more of it every day.” – Tim Spector

"If your goal is to have a healthier body and mind, this is the book for you." – Joe Wicks


Goodbye high-protein, hello fiber!

The importance of fiber in our diet and its impact on our overall health cannot be understated, yet 96% of us aren't consuming enough.

Sunday Times bestselling author and industry-leading nutritionist Rhiannon Lambert is here to unpack the benefits of fiber, and outline the growing recognition of the importance of good gut health on alleviating a wide range of common complaints and health conditions. The solution is simple: 30g of fiber a day + eating 30 different plants a week will drastically improve short-term discomfort and fatigue, and lead to a much lower risk of developing more serious health conditions in the future.

Alongside this clear formula Rhiannon offers 60 minimally processed recipes.

Recipes include:
Breakfasts:
Potato farls with an avocado smash, Barley porridge with blackberry and bay compote
Nutritious lunches: Coronation Brussels sprouts & chicken salad; Veg-filled summer rolls
30-Minute Dinners: Green butterbean mac & cheese, Steamed cod & white beans
Fiber-filled Twists on a Classic: Champion chocolate chili, Baked aubergine Milanese
Snacks: Vegetable bhajis with coriander chutney, Popcorn – 3 ways
Desserts: Chickpea blondies with tahini & raspberries, Rice pudding with salted pear compote

With plant points and macronutrient figures included for every recipe, this book empowers everyone to get the formula right and hit their recommended 30g of fiber every day.

––––––––––

"Fiber sits at the heart of so much of our health, yet it’s been quietly overlooked while the conversation has been dominated by protein and quick fixes. Rhiannon’s book brings it back into the spotlight in a way that’s clear, accessible and incredibly timely." – Ella Mills
