If you've got so much muscle you are in the obese category without being fat, you're pretty damned ripped.
Now, I would say that it would be pretty easy for someone to be in the overweight category purely from extra muscle.
But to go from normal to obese purely on muscle alone seems unlikely to me. I would think that someone can be slightly overweight but their muscle pushes them into obese-land. But the combination of low body-fat% and an obese-range BMI is probably reserved for the elite level of bodybuilders.
edit: say, for example you have a 5'8" person. 24.9 BMI (just at the edge of normal) is 164 lbs. To get to obese, he would have to be 197lbs for a BMI of 30. Assume he added pure muscle to get there. That's 33lbs of muscle. Not impossible, but it's also not a trivial amount of beefcake. Joe Blow isn't going to get that to happen just by deciding to pop into the gym for 3 weeks.
Not remotely true. That completely fails to account for body type and muscle density.
For instance, at 5'10" with a bioelectric impedance reading of 14% I weighed 205 pounds. That's a BMI of 29+, but I had a 28" waist and was in very good shape. However, I wasn't 'pretty damned ripped', just big in the legs, chest and shoulders. I didn't look like a body builder (and had next to no cut), just a big guy.
Samoans and other ethnic types are even more affected by their different physiology.
