Team Scivation seemed to have scored heavily on this one with their controversial author, Chuck Rudolf.
He came out a year ago when he introduced his diets - low-carb / low insulin that actually builds muscle mass while lowing fat.
He’s the only dietician i know that doesn’t prescribe post-w drinks but instead eats whole meals 45-60 min after exercise. instead, he uses whey isolates and BCAAs during workout.

NOTE: Chuck used this diet on an IFBB pro, quincy taylor, and made him enter his first ever mr. olympia contest
