A Myth-Busting Guide to Diet and Nutrition in a World of Misinformation


‘Incredibly well written, accessible and a must in every household.’ Dr Nighat Arif, author of The Knowledge and resident doctor on ITV This Morning

‘A fabulous read!’ Rhiannon Lambert, Registered Nutritionist and Sunday Times bestselling author of The Science of Nutrition

Are carbs the enemy? Am I getting enough protein? Should I worry about inflammation? Do calories count? And do any diets really work?

We are constantly bombarded with advice on how to live a ‘healthier’ life. From the benefits of intermittent fasting and the keto diet, to the growth of veganism and the dangers of inflammation, poor-quality, dubiously sourced information on how we can live and feel better is everywhere. But where should we turn for advice we can trust?

Dr Idrees Mughal (Dr Idz), an NHS doctor with a masters in nutritional research and a board certification in lifestyle medicine, has made it his mission to educate, inspire and empower the public when it comes to diet and lifestyle. His signature videos have attracted millions of followers online, and now he’s collected this wealth of information in his first book, Saturated Facts – your science-backed guide to living better.

Whether you’re looking to lose weight, sleep better, avoid disease or just have more energy as you go about your day, Saturated Facts is the comprehensive guide you need to make smarter decisions about your health.


  • Every page, I spent it in a jaw-dropping moment thinking “I did not know that!” Incredibly well written, accessible and a must in every household. Well done Dr Idz
