David Asprey

David Asprey is an American entrepreneur, author, and icon of bio-optimization, recognized worldwide as the creator of the Bulletproof Diet and Bulletproof Coffee. His work focuses on applying the biology of high performance to increase energy, improve brain function, and promote extended longevity, based on the idea that health can be “hacked” using scientific methods.

His career began as a successful executive in Silicon Valley, where, despite his young age, he struggled with being overweight, brain fog, and various health issues. This situation led him to invest hundreds of thousands of dollars in medical tests, scientific studies, and innovative methods, embarking on a personal quest to understand the causes of his poor performance and optimize his biology. This period of intensive experimentation laid the foundation for his entire subsequent philosophy.

The discovery that launched his fame came during a trip to Tibet, where he tried a local tea mixed with yak butter. Upon his return, he developed his own version made with coffee, butter, and coconut oil, thus giving birth to Bulletproof Coffee, which became the foundation of his successful company and nutritional philosophy. With this diet, Asprey reported significant weight loss and a dramatic improvement in his concentration and mental and emotional well-being.

Asprey is the author of several bestsellers, including *The Bulletproof Diet* and *Head Strong*, in which he shares his bio-optimization and neuroscience protocols. His approach is based on reducing toxins, prioritizing healthy fats and intermittent fasting, supplemented by a vast array of supplements. His legacy is having popularized the concept of “biohacking” and having spearheaded a global movement that seeks to take control of personal biology through nutrition and technology.
