I am 5ft 4 and 8stone 13. When I looked on the body fat calculator it said that I am obese but the bmi says I am 21 which is correct and healthy size. Which one do I take to be true? I had my little one a year ago and put on 5 and a half stones. I am really quite small framed and a size 10 top and 10/12 bottom. I do have a belly which im finding it hard to get rid of but i dont think im obese.
