Start with small changes. My first change as part of my journey was walking 20 minutes every day. My second change was removing 70% of added sugar and processed food from my diet. One week in, I was already sleeping better and feeling better. As an added benefit I also dropped 8 lbs in my first week (from 265 down to 257). My blood sugar was in the range 0% of the time and my highest spike was 401 mg/dl. Worth noting, I was both with a bilateral club foot and have never been able to walk long distances (or run) comfortably. As I result of my club foot I have arthritis in both of my ankles. Onward and upward!
