The normal BMI range may not be realistic for some. I would like to get to the top of the normal range 184# but it has been a few decades. I would hate to go the effort to to lose down to an unrealistic weight that I could not maintain, as that is the hard part. I can gain quite fast but losing seems to be getting harder. Good luck with your weight loss endeavour.
The bottom of the normal range would not work for me, pretty sure of that.
