Keto Flu or Sugar Buster

I am on day 13 and the last few days I was nauseous after eating but still hungry :(.  Yesterday on day 12 I felt really bad and had no appetite. So I did not eat but 1/2 of what I had planned.  I finally laid down for about 15 mins and went to bed 2 hours early.  

Today I am down 10 lbs in 13 days :). The phrase no appetite was never in my vocabulary as I could have the flu and still eat.

Yeah KETO
