So long as the caloric intake is solid I think it really enhances recovery. I think the adaptations are VERY endurance/metcon specific as well.
Many people have noticed an improvement in max strength...people like Kurtis Bowler who have really pushed that max strength element. That is honestly surprising to me as the adaptations seem to favor a fiber type conversion and tendency towards endurance adaptations. It could be that one will not create a TOP level Olifter, PL'er or sprinter on intermittent fasting, the well fed state is very favorable to the type 2b fiber type expression, but for the endurance athlete or strength-endurance athlete it may be very beneficial.
