On Monday, the founder of David Protein, known for its popular high-protein nutrition bars, announced on X that longevity expert Dr. Peter Attia has officially resigned from his position as Chief Science Officer at the company.
This announcement follows the release of over 1,700 documents, including email exchanges, linked to convicted sex offender Jeffrey Epstein, as reported by The New York Times. Dr. Attia was part of the executive team at the food startup and was an early investor in the company.
For those not acquainted, Dr. Attia is a Canadian-American physician recognized as a leading authority in the fields of longevity and preventive health. He is most renowned for his bestselling book, “Outlive: The Science and Art of Longevity,” and for his podcast, which has been running for seven years and focuses on optimization strategies. Recently, he was also appointed as a contributor to CBS.
Founded three years ago and based in New York, David Protein secured a $75 million Series A funding round in May of last year, led by Greenoaks and supported by Valor Equity Partners. The company has seen remarkable growth since launching its flagship protein bar in September 2024, a product boasting 28 grams of protein, zero sugar, and only 150 calories.
In a detailed post on X, Dr. Attia expressed that he felt “ashamed” of some inappropriate content found in his emails with Epstein. However, he clarified that he was not involved in any criminal activities and had never visited Epstein’s island or traveled on his plane. Dr. Attia elaborated on his relationship with Epstein and the reasons for his continued association with him, even after Epstein’s 2008 conviction.
The ramifications appear to extend beyond David Protein. It also seems that Biograph, the healthcare testing and longevity startup co-founded by Dr. Attia and entrepreneur John Hering, may be distancing itself from him. The company declined to comment on Dr. Attia’s current involvement with Biograph or address the pages on its website that previously mentioned him but now either omit his name or generate a “file not found” error.
Biograph emerged from stealth mode a year ago and has received backing from investors including Vy Capital, Human Capital, Alpha Wave, WndrCo, and angel investors like Balaji Srinivasan. Similar to a growing number of concierge medical service firms, Biograph offers premium preventive health services to subscribers, who pay annual fees ranging from $7,500 to $15,000. Dr. Attia was previously highlighted as a co-founder in the company’s press releases and website.
