No matter which formula you're using, it's nothing more than a starting point. It's the variable monitoring that matters.
yep, i tried 2400 for just a few days and i could just tell that it was too damn little
now i'll go with 3 grand and monitior from there
but what i'm curious about is his idea about marco ratios
most sites say 40/40/20 pro/carb/fat
but others say 30/40/30 and even 33/33/33
