In today’s episode, Stuart talks to Danny Lennon from Sigma Nutrition about the considerations you should have if you’re thinking about starting a podcast, what he thinks has helped his podcast grow to the level it has, Danny’s three-part framework for describing what is health and what he thinks about to ensure he’s living a meaningful life. It gets deep at points but I wouldn’t have it any other way as this was one of the most enjoyable interviews I’ve done in a long time!

Danny is the founder of Sigma Nutrition and head of content creation for the company. Known for hosting the top-ranked podcast Sigma Nutrition Radio, Danny is also a respected educator in the field. He has spoken at conferences and events all over Europe (including London, Dublin, Amsterdam and Vienna), as well as the United States and Australia.
