The Diet Myth: Learn how to make better nutritional choices

  • The Guardian Kings Place, 90 York Way London, England, N1 9GU United Kingdom (map)

Join author of The Diet Myth, professor Tim Spector, to find out the reason most diets fail, why we should learn to love our microbes and how we can change our view of food and make better nutritional choices.

Are you stuck in a food rut? Do you feel as though you’re constantly trying different diets and following new food fads but never managing to lose weight or feel healthier?

What we eat has a huge impact on our health, but recent evidence shows that we all respond differently to the same foods and that our genes are only part of the answer. 

Thanks to recent scientific breakthroughs, researchers have started to examine the permanent residents of our guts – the trillions of microbes, bacteria and fungi that digest our food, produce vitamins and regulate our immune systems. Ongoing research has revealed how these microbes are essential for our continued good health and how, by ignoring them, many of us are failing to make the best food choices.

Join us for an illuminating masterclass with Professor Tim Spector as he talks us through some of the amazing discoveries that have come to light during his career at King’s College London – many of which form the basis of his book The Diet Myth. 

He’ll explain why most diets are destined to fail and why we we need to increase the diversity of our microbes to improve our health. You will leave the evening with the ability to make better choices about your personal nutrition and lifestyle.
