Also... with all the running she does AND her TDEE which has gotta be through the roof since she's huge, she most likely doesn't have to limit herself to 1500 to lose weight. She could probably eat 2000 calories a day and lose. I haven't done the math on this, but I'm training for my first ultra (I currently run marathons) and I've been losing weight eating much more (most days) than 1500 cal/day... AND I'm human-sized, so lower TDEE.
