What is the ideal body weight for a person? If this question has been troubling you, then your wait has ended. The ideal body weight of a person can be calculated based on the gender and height of the person. Everyone would like to be fit and active. But when we cross the limit and become obese, this may create many health related issues. The standards are set based on research and survey for appropriate height and weight. This can be assumed to be the desirable or ideal weight which can help you live a long and happy life. This measure can be used as a guideline but a physician's advice should also be taken before taking any extreme measure.
