The above photo is from today's easy 5 miler, and just before I took the photo huge snowflakes were dropping! Then the sun came out!
Day 29 of low carb high fat eating and I feel great! Never hungry. The oddest feeling! I feel totally normal and am out of the funk that is the "induction" period transferring to ketosis. It wasn't too bad but now I feel the difference. I got some stick to pee on to see how far into ketosis I am but normally can smell the acetone secretions.
Rather than explain the whole thing this dude's website does an excellent job of explaining it all:
