First I want to say that I have been following the atkins diet for over a year now, and have lost nearly 60lbs. The last month or so I have not been able to lose any weight at all, and I have checked the keto sticks to ensure that I was still in ketosis. I know we all have plateaus, but my actual questions below is what's boggling my mind.

So I have been sick lately, and when I got up Tuesday morning I weighed myself. After throwing up once, going to work, which meant sweating outside all day, and drinking only water. I went home. When I got home, I fell asleep all day, slept for nearly 12 hours, then when I got up I used the bathroom, went both number 1 and number 2, and then when I stepped on the scale out of curiosity, I was 2 pounds heavier than Tuesday morning... All I had eaten the whole day was 2 sasquach sticks from 7-11, 2 carbs each, I got during lunch, which are basically just slim jims. I used a keto stick to see if anything had knocked me out of ketosis, and I was still fine. This just makes no sense to me, and I have no idea how I managed to go up 2 pounds. Any ideas?
