I put on 5 lbs in 2 weeks cause I started to eat donar's. After realizing what was happening I stopped eating them. That was 2 weeks ago, but I still have the extra 5 lbs. I know 5 lbs isn't that much, but when my weight hasn't changed in over a year then all of a sudden gained, it's put my sysem out of whack. My back hurts more, when I lean forward I feel my gut pressing against my chest, causing chest pain, I'm more tired and tirer easyier. It's nuts to notice it more. Just from a 5 lb gain. It's weird.
