Fat is such a complex topic it would be hard to spend enough time refuting the last statement. But, in short it depends on what kind of fat (body fat? (if you're in a catabolic state, you will be "eating" your own fat; and this too has different types, depending on what your diet was!),trans,polyunsaturated,saturated,mono), how active you are, how much you consume, whether you're in ketosis/adapted, as well as a host of genetic factors,which determine your lipase production. Mostly agree on the "like steak" part, though that too would take a long time to, umm, break down.
