In this interview, Sam Parr talks with entrepreneur and investor Justin Mares about a wide range of health‑focused business opportunities and his own ventures. Mares explains how his bone‑broth company Kettle & Fire grew to a $100M+ run‑rate with a lean, AI‑driven operation and why he believes legacy CPG giants are bloated and often harmful. He highlights macro trends such as the pet‑health market (fresh dog food, water filtration, toxin‑free accessories), the push for full‑chain food transparency through his brother’s lab‑testing startup Light Labs, and the explosion of consumer‑facing biomarker services like Function Health and Superpower. Mares also discusses home‑environment health assessments (Lightwork), the potential of integrating gut‑health science with skincare, controversial stances on sunscreen, polyester clothing, and the U.S. vaccine schedule, and he shares his vision for future creator‑led distribution models. Throughout, he emphasizes capital‑efficient growth, the role of AI in operations, and the importance of data‑driven transparency to drive consumer demand and industry change.
