new member, help needed please

Hi there,

I am new to this forum and was wondering if someone may be able to help me out with a question I have. I have previously been on the atkins diet and lost 2 stone but recently have fallen off the wagon and put 1/2 a stone back on. Anyway I am now 4 days into induction again and have been measuring for signs of ketosis with ketostix. Yesterday however I registred as positive however today its showing a negative, any ideas why this could be. I havent eaten anything different nor do I drink caffeine of soft drinks with aspartame.

any advice would be much appreciated.

thanks in advance

There is an atkins section on this forum and they are all experts in ketosis so might be an idea to ask there.
