its exactly what i did, over the course of the last four yrs, i started out as 18.5 stones of mostly fat, but knew i had alot of lean muscle underneath, desperate to rid myself of the fat, i did unbelievable amounts of cardio before eating and dropped down to 14 stones, people started to tell me i was getting skinny, but i was still fat if u know what i mean. i lost nearly all my lean mass and it deos hurt knowing all the wrong effort you put in ive managed to work back up to 16.5stones again 20% bodyfat buy eating before cardio and training.
