lets see if i understand this correctly:
hypothetically youre 182lbs 18%bf and have 149.24lbs LBM (32.76lbs FAT)and want to get to 182lbs 10% bf which is 163.8lbs LBM (18.2lbs FAT)
this is a net gain of 14.56lbs LBM and net loss of 14.56lbs FAT..
the author's contention is that by feeding the lean mass of the desired weight and bf% you can get there?
lets run the numbers:
182lbs 18%bf and 149.24lbs LBM means:
rough maintenance = LBM x 15
149.24 x 15 = 2238.6calories per day rough maintenance
182lbs 10%bf and 163.8lbs LBM means:
rough maintenance = LBM x 15
163.8 x 15 = 2457calories per day rough maintenance
2457(10%body fat) - 2238.6(18% body fat) = 218.4 calorie difference for maintaining weight
so the guy who is 10%body fat requires 218.4 more calories than the guy who is 18% body fat.
the author contends that in order to lose 15 pounds of fat and gain 15 pounds of muscle all you have to do is eat at a 218.4 calorie surplus??

i think NOT!! if only it were that easy...
IMO there is no way in hell you are gonna lose fat eating at a surplus of calories than what ur current LBM requires. the author is incorrect IMO. (id also like to note i would even suggest he is an idiot if i were in the mood to be an asshole
