Ah, ok. I still say it's a goofy exercise in dehydration tho with nothing but downsides and possible health consequences.
What's 16 lbs, near 15% of your body weight? Any coach who insists on this is no coach at all. You might consider telling him to go suck an egg.
Only thing he's insisted is that I make my weigh-in. How I do it, at this point, is on me.
