At just 22 years old, Spencer Miller is an elite cyclist from Indiana who has been focusing on fitness and nutrition for 7 years now (yes, that means he started when he was 15). He started his Instagram account, @macro_chef, with the intent of being healthier and still having the delicious treats he loved. It morphed into a business where he creates macro-friendly recipes for some of the biggest supplement companies in the industry. Armed with the knowledge he's acquired over the years, he recently started his own supplement company, Macro Supps, where he sells a superior baking / cooking protein powder as well as a premium greens supplement.
