Mahdi Yusuf worked a startup in his twenties and wasn’t worried too much about his health. When he quit that job, he decided to take better care of himself and lost fifty pounds. Now, he’s the CTO of Gyroscope, a startup that aims to be the operating system for the human body, but ever since joining, has gained weight back.

Mahdi talks to me about how Gyroscope is trying to help people understand their bodies better, growing up with a love for computers, and trying to be healthy with a busy life.
