Ketones NEGATIVE!

What is Ketosis?
My sister suggested I buy some Ketostix to enable me to forego the daily weigh-ins. (Ketosticks are these strips that you pee on, and they measure the amount of Ketones in your urine. Ketones are released when your body is using your fat stores for energy ie. weight loss mode)

My ketones this morning were negative, NADDA, NIL! The stick had not even a *hint* of ketones on it! :(
How bummed am I? So bummed, I forgot my weekly weigh-in today, and I already ate breakfast!
