Fat v. Muscle - I choose muscle

I've often heard it say that 5 pounds of fat weighs more than 5 pounds of muscle.
But doesn't that sound odd to you?
Doesn't 5 pounds just equal 5 pounds whether it's a fat or muscle or pinto beans or paper?
Yes...I think so.
But look at the difference in the amount of volume fat takes up.
that 5 pounds of fat is just all oozy everywhere...whereas the muscle is lean, sleek, dense.
So, as I ponder the whys of eating paleo and exercising... it's to get a more lean, sleek appearance that is healthy and fit.

5 lbs = 5 lbs
Just sayin'
