Sorry if this is a dupe thread. Could not find. So Conor was supposed to face RDA at 155 in 2 weeks. The day RDA announced he was out, reports said that Conor was walking around at 174 or 177, I forget. My assumption is that when he fights at 145, he'd probably be 10 lbs lighter so let's say 164. In any case: how is it possible for an elite athlete to cut 20 lbs in two weeks. Clearly they don't have much in the way of fat to lose and I can't fathom that there's 20 lbs of water to lose and rehydrate. In cases like Johny, he balloons up, but conor is nearly always fit and other fighters typically look pretty healthy too. So where does that weight come from? And how do they lose it?
