The Bulletproof Diet describes how focusing your diet around good fats, healthy proteins, and few carbohydrates can help us lose weight, gain energy, and focus.

There's so much information out there these days about what, when, and how we should be eating.

With fad diets, different types of fats, and encouragements to go plant-based, it can feel almost impossible to know who to listen to.

Dave Asprey created a video about Bulletproof Coffee made from a blend of butter and coffee - and it went viral.

Since then, he's developed a whole diet and an entire brand around it, and he's become one of the most popular approaches to health and fitness in the Western world.

In The Bulletproof Diet, Asprey outlines his key rules to follow so that you can choose your food more deliberately, stay nutritiously healthy, and feel happier.
