To give more detail:

  • 100kg male
  • fast with only water (and salts) and/or coffee allowed
  • low activity (computer desk job)

I'd like to keep the muscle loss to a minimum by adding only protein to the 7 day fast.

What is the percent (from the protein + carbs + fat total) of protein burned from muscle loss on a fasting day so I can counter it with added protein?

  • If you want to keep muscle loss to a minimum, you’re actually doing the opposite of what you’re trying to accomplish. – JustSnilloc May 21 '18 at 18:44

    If you're adding protein, you are no longer fasting. For what purpose is the 7 day fast? – JohnP May 21 '18 at 19:38
  • @JohnP I've been following Nassim Nicholas Taleb's advice with 1 day / week, 3 days in a row / month and 7 days once a year. Basically trying to get the health benefits of autophagy - letting the cells that should die out, die; increasing insulin sensitivity. I've been doing this for 5 years now. – StefanS May 21 '18 at 19:52
  • Please elaborate on your question. Just asking "what is the percentage of protein burned" does not make sense, as all protein consumed is burned regardless of whether you are fasting or not, in the sense that it has caloric value and you are consuming it. – David Scarlett May 22 '18 at 0:59
