If I went by  http://www.lowcarbliving.com/ccounter.html:


                                  carbs  fiber  cal     protein   fat
1.5 lb ribeye                     0      0      1528    142.8g    80.0g

which is about 3600 calories. I guess I thought there was more fat in
ribeye and chicken thighs.
