i did this for awhile, just because for the fact that protien shakes were making me throw up. i gotta say, just eating whole clean food only i became leaner but i wasnt able to put muscle weight on, i couldnt pin point what i was doing wrong. ive been adding in shakes for the past two months and ive gained 5lbs. im just as hard as i was two months ago, but ive been doing slightly more cardio to so, idk that could be the reason for my leanness
