David Asprey

David Asprey is an American entrepreneur, author, and icon of bio-optimization, known worldwide as the creator of the Bulletproof Diet and Bulletproof Coffee. His work focuses on applying the science of high-performance biology to boost 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 weight issues, brain fog, and various health problems. 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 formed the foundation of 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 state.

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 focuses on reducing toxins, prioritizing healthy fats and intermittent fasting, supplemented by a wide range of supplements. His legacy lies in popularizing the concept of “biohacking” and spearheading a global movement that seeks to take control of personal biology through nutrition and technology.
