If you are going by what you consider your ideal weight then ok, but the chart for ideal weights is BS. Ignore it. You are also better off avoiding scales. They are misleading. You weight will naturally fluctuate over the course of the day. You are far better off using a mirror.
I am speaking of the life of a man who knows that the world is not given by his fathers, but borrowed from his children; who has undertaken to cherish it and do it no damage, not because he is duty-bound, but because he loves the world and loves his children… - Wendell Berry, 1971
