I don't know if it's water, fat, or muscle, well its not muscle but I fluctuate weight like you wouldn't believe. But like I've said many times I am in the 260' to 270's. If they would open the fitness center back up I would be lower, I have found alternatives.... but they don't compare. Before I started doing anything, I would see three and four pound differences in a day. When you see that you know you are very overweight. I said it was water. But i was at a plateau at 264 lbs. Then the dead guy and all closing of fitness room and I just have my mountain bike and it's 20 degree's outside. What this has to do with the thread I don't know, because I lost myself because I cannot work out. Dag............. sad...............
