Yes, I think she just works out alot. I have to admit, that is a look I find attractive- but in fitness, not in starvation. I try and eat a balanced diet, and get in 4 weight sesions per week and run at least 30 miles per week. Fitness is a huge part of my life and I see many women who achieve BMI like hers. I'd say she's about 15%. A good goal for those of us in real life- not in beauty pageants or fitness competitions- is around 20%.

Whether you like her look or not, hers is achieved in the gym, not over the toilet. An anorexic would not be able to sustain that muscle tone.
