I workout every day. i do cardio 7 days a week and lift about 5-6. on my easy day, i feel like i can't eat as much or any protein. should i eat it?

Yes: Sounds like you're pretty active into fitness and protein should be a big part of your diet. The amount of protein you take daily depends on your goals, muscle building vs. cutting down vs. fat loss. I recommend 1.2 to 1.5 mg/kg of protein a day in order to maintain positive Nitrogen (anabolic) balance. Go to www.bodybuilding.com as they have good instructions on Nutrition based on goals.
