# Wellness Expert Departs David Protein Amid Leadership Shake-Up
In a surprising turn for the high-protein snack industry, David Protein, the innovative bar brand boasting 28 grams of protein in just 150 calories, has seen a major leadership change with the departure of its Chief Science Officer, Peter Attia, MD. The exit of the renowned longevity expert, co-founder of Early Medical and author of the bestseller Outlive, signals a potential shake-up as the company navigates rapid growth and expansion plans.[3]
Peter Attia's Role and Contributions to David Protein
Peter Attia joined David Protein as Chief Science Officer, bringing his expertise in longevity, healthspan optimization, and nutritional science to the forefront of the brand's mission. A Stanford-trained physician with residency at Johns Hopkins and research at the National Institutes of Health, Attia focused on immune therapies and Medicine 3.0 principles—aiming to extend both lifespan and healthspan through evidence-based nutrition.[3] His involvement lent scientific credibility to David's bars, which prioritize maximum protein per calorie (CFP) with zero sugar, aligning perfectly with Attia's advocacy for high-protein diets to build muscle and reduce fat.[1][3]
Under Attia's guidance, David differentiated itself in the crowded protein bar market by emphasizing efficiency: delivering ~50% more protein per calorie than competitors. This science-backed approach fueled the brand's TikTok virality and retail expansion into convenience and grocery stores nationwide.[1]
David Protein's Meteoric Rise and Recent Funding Boost
Co-founded by CEO Peter Rahal (formerly of RXBar), David Protein has exploded onto the scene with a clear mission: "remove unnecessary calories and sugar from the American diet and replace them with high-quality protein."[1] The company recently secured $75 million in Series A funding led by Greenoaks, following a $10 million seed round, totaling $85 million raised. This capital is powering manufacturing scale-up, inventory growth, and accelerated product development.[1][2]
A key move was acquiring Epogee, creators of EPG—a plant-based, low-calorie fat alternative already in David's bars for superior taste without extra calories. Developed at Kansas State University, EPG positions David to potentially license the tech beyond bars, with prototypes like protein-packed, low-calorie ice cream in the works.[1][2] Rahal remains focused on making David the top protein bar, while eyeing future products that "increase muscle and decrease fat."[1]
Implications of the Leadership Shake-Up for Investors and Consumers
The departure of Peter Attia amid this growth phase raises questions about David's scientific direction, especially as CEO Peter Rahal continues promoting the brand on platforms like CNBC, discussing protein's role amid GLP-1 drugs like Ozempic boosting demand.[4] While no official reason for Attia's exit has been disclosed, it coincides with the company's pivot toward broader retail expansion and ingredient innovation.[1][2] Investors watching high-protein startups may see this as a recalibration, with Rahal's operational expertise steering the ship toward category dominance.[1]
Consumers benefit from David's unwavering formula—28g protein, 0g sugar, 150 calories—but the shake-up could influence upcoming products like ice cream or creatine-enhanced bars.[2][4] The brand's emphasis on taste (described as "chocolate-covered marshmallow") keeps it competitive against fads like keto or all-natural trends.[1][2][4]
Future Outlook: Expansion and Market Challenges
David Protein eyes retail dominance and potential category expansion, leveraging its $75M war chest for EPG production and new launches.[1][2] Challenges include scaling supply amid surging protein demand, especially with weight-loss meds increasing intake needs.[4] Rahal's vision remains product-led: no compromises on macros or flavor.[1]
