Nutritional shift

Dietary changes made this year after my 50k run, which consisted of a 3 months on a mostly vegetarian diet (Jul-Sept). I’ve been back to eating meats (but less), but also have avoided sugar and grains. Around Nov, I found my diet evolved to low carbs and high fats. Nowadays, I believe I’m intermittently in nutritional ketosis and back in Nov 28, via Ketostix urine test strips, I confirmed having levels of ketone bodies, which I’m happy about. Essentially, these dietary changes since July helped get me to my goal weight of 140lbs and train my body to rely on fats for fuel on my runs and less on sugar.
