I have been eating paleo for 1 1/2 weeks, and feel really good. I have been working out 3 days a week and walking most of the others. The weight loss has not been much, which is strange since I have been in ketosis since a few days after starting. The one thing I noticed was there is a large variation in the color. Sometimes it might only register a trace and other times it might regester moderate? Is this normal? I am eating way less than 20 grams of carbs. Any thoughts? Thanks Jim Hutchinson
