Fat fast calories

I am about to start on the fat fast diet, how do i figure the amount of calories i should take? How many calories does protein have per gram? Thanks for your help.

Depends on how strictly you’re going to follow it. If you have the Androsol/Nandrosol, Brock’s recommendations were to use the Owens formula (BW *10.2) +879, then multiply by .5 or .6-this is your recommended calorie level. W/O the Andro/Nandro there’s no way you can go this low and not lose muscle so in this case either carb-up once a week or up your calories to 12x bw or so. Good luck!

Protein has 4 cal/g.
