I thought I heard once that your metabolism goes up when you are sick.
Seems likely given my current situation. I had already lost my water that I lose when I stop exercising because I have been injured and my family has been sick. Now I am sick (for the past week) and I am losing faster than before. I know I am slightly dehydrated no matter how much I drink, but still.
Will be interesting to see what happens when I recover, how much is real and how much is water.
