I am using an eat when hungry approach mostly now and doing aerobics and weights,both starting the weights up today 3x weeka and been doing aerobics 5 x week for long time year or more but only could maintain with the aerobics and former eating and was maintaining at 250 to 260 and should weigh likely 180 to 160. I dont' care about bmi think its mostly crap. But do care more about bodyfat and muscle mass.
