5500 kcal? What are you? A lumberjack working all day on giant redwoods with only a hacksaw?
The percentage isn't really relevant here. The point is that 260 g is more -- correction, far more -- than you need for body repair. You're only 140 lbs for goodness' sake, your lean mass probably less than 130.
Effectively, you're using most of that for fuel. This is like trying to run your car on fiberglass and spray-paint instead of fuel. Well ... not quite, because metabolic flexibility being what it is you can do it. You'd just far better not.
