Wow. I have been doing some research. It appears that I have lost about 2 pounds of lift. That doesn’t sound much but that is about 40% of the buoyancy required to keep a person afloat.
The biggest thing I noticed was that I was floating vertically! That was scary. But, now it makes total sense — and this diagram shows it all.
Most of the 20 pounds of fat came off my waist and a bit off my chest.
Having that fat on my waist previously lifted my waist up so that I was horizontal. Now without that fat, my lower body sinks.
I am sure that I will get used to this.
Divers know about this. When they lose weight they reduce the amount of free weights they use.
But, I am not sure whether this issue is ever talked about in normal weight loss discussions. This could be dangerous. Somebody who has say lost 50 pounds might think that he/she can now swim better and dive in — without realizing that they are going to experience one heck of a shock.
