On Tuesday this week I went for Life-Line screening and found out my height has dropped by 2 inches! because of this my BMI has gone up. Is there a different BMI calculator for old people? I am now obese, for me to be in the range of correct BMI, I have to loos 28lbs. for me this is impossible as I want to enjoy life and live, if I lose 14lbs then I will be the same weight as when I was 18, I am 67 now. Would appreciate any offer of help.
