In this episode of the Biohacker's Podcast, Teemu Arina is joined by Jan K. Górczyński - the founder and CEO of BeKeto, a leading brand in the keto and low-carb market across the UK and EU.

In just five years, Jan expanded BeKeto to offer nearly 200 products across multiple categories, achieving a presence in 30 countries. As a serial entrepreneur, his companies generate over 10 million EUR in revenue. Jan is passionate about the execution in both life and business and is deeply committed to healthy living. He is an enthusiast of low-carb and keto diets, biohacking, and enjoys frequent sauna sessions.

Teemu and Jan dive into the evolution of ketogenic nutrition, metabolic performance, and the data-driven approach behind BeKeto’s product line. Jan explains that the company emerged from a gap in the European market. By focusing on ingredient purity, transparent formulations, and repeated glucometer-based validation, BeKeto positioned itself as a trusted source for individuals pursuing sustained ketosis. The discussion emphasizes how stable energy, mental clarity, and appetite regulation arise when the body shifts from glucose dependency to ketone-driven metabolism.

Teemu and Jan further explore the role of exogenous ketones, ketogenic snacks, and electrolyte formulations in supporting performance, recovery, and cognitive output. They highlight consumer misconceptions - particularly the confusion between “dirty keto” and true metabolic ketosis - and underscore the importance of consistency, clean ingredients, and adaptation support. Looking ahead, Jan predicts a convergence between ketogenic nutrition and continuous metabolic monitoring, enabling individuals to tailor diet and supplementation with precision. The episode concludes with a shared message: ketosis is most powerful when approached as a long-term, sustainable lifestyle rooted in intentional choices and measurable data.
