in exercise, is it really true that "no pain, no gain"?

<p>

the bioavailability of protein in lean meats and fish is much higher than that of plant-based food. a poor diet consists of too much cheap and fatty meat, not necessarily too much meat. egg protein is actually the best. beans, nuts, plants, etc. are great for you but shouldn’t be your main source of protein intake.
