> You can lose considerable muscle mass BCAA

• naasking 8y ago
  BCAA are not zero calorie, contrary to popular wisdom, so you can't consume them during a fast. It's a regulatory loophole that amino acids don't need to be counted towards the caloric total.

    If you do intermittent fasting (16-24h), you can eat it during the non-fasting periods and it should help with muscle loss. Also, you can do HIIT during longer fasts to keep muscles "in demand" so that proteins aren't recycled by your body to usual extent. There was some study about it somewhere...

      Yes, resistance training and high protein intake minimize muscle loss in a caloric deficit.
