doing a LOT of cardio

[woje3]

If I'm trying to cut bodyfat as much as possible, what is more important to maintain as much lean body mass as possible if I'm doing around 90 minutes of cardio a day on the treadmill of interval training??? would taking an ECA stack be more important, or getting enough protien...my diet right now is a zone (40%carbs,30%protein,30%fat)???????

With that much cardio, both will be important. To maintain a high level of mass, that is an awful lot of cardio. Obviously everyone reacts differently to diet & cardio. For me, it would be much more effective to do 30 minutes a day of cardio, way up the protein and decrease the carbs......
