I got booted out of a Ketogenic Facebook group for espousing macros supposedly out of line with their stated numbers.
I looked up their macros on their Macro Calculator.
The group macro calculator says:
I suggested that my goal weight is 220 lbs and that would make my numbers 110 grams of carbs and that I am only at 120g of Protein so I am within less than 10% of the stated macro. Hardly too much Protein.
I was told that was too much Protein. Men, she said, should not eat more than 80 g of Protein in a day. So I did the math with their own macro calculator. That would say that men should not weigh more than 160 lbs (80 grams of Protein corresponds to a goal weight of 160 lbs per their calculator).
How dare they say that men, regardless of their condition, should never weigh more than 160 lbs.
Below is an example of how you could calculate the protein needs of a 180-pound lifter who has 15 percent body fat:
180 lbs. x 0.15 = 27 lbs. of fat
180 lbs. – 27lbs. = 153 lbs. lean mass
153 lbs. x 0.6 g = 91.8 g
153 lbs. x 1.0g = 153 g
Protein range = ~ 92-150 g per day
