I don't think it's a completely unanswerable question. At 258 and 16%; He has a LBM of 216 lb's, and wants to get to 235 lb's(I subtracted 5 lb's for water weight, and this figure is assuming he eats enough protein, and possibly some anabolics, and doesn't lose any muscle). thats app. 23-25 lb's, and at 2 lb's a week(the max for fat loss w/ out muscle loss) thats about 11-12 weeks. Good luck
