I see that a lot of people here are eating protein amouts that a pretty high....40-50%....and low on carbs....30-40%. I always thought that if too big of a percent of you calories were protein, your body would learn to use protein as an energy source rather than building mass. I know for a cutter you should up protein and cut carbs. Say for a lean bulk, What ratios would you use? Should protein be cycled to avoid putting your body into a protein wasting state, due to too much excess protein?
