I agree, it seems more than improbable. People think of body fat as solely subcutaneous fat and maybe that is what they are referring to. Subcutaneous fat is also called "depot" fat. It is used as a calorie reserve for lean times.


But fats include lipid bilayer membranes. Cells have all sorts of membranes in them: endoplasmic reticulum, mitochondria, cell membranes, golgi apparatus and so on. Membranes are fat. Without membranes you would be sort of like jello.

Also nervous tissue has a very high fat content in the form of phospholipids.

Another purpose that fat serves in the human body is as a cushion for certain critical organs like the kidneys. It serves as a sort of shock absorber.

Also, bone marrow is very high in fat and that is not something one can do without either.

I would think that a living human would have to be more than 2% fat to even be alive. Now maybe Ohno had been measured for body fat and it gave that reading but that does not mean that is what his percent body fat actually is.
