How much fat does an elderly person need?

Fat doesn't really matter as much as your body mass because other types of tissues are more important. Check your BMI, there's plenty of websites out there to help you and try and get to your ideal weight.

It is important that if your are elderly, you stay fit and don't have too much fat stored around. If you are over 50 your chances of having Heart disease is doubled and only increases from there. If you have excess fat those numbers can increase even more so it is so important that you make sure that you are healthy, fit and have good blood pressure, or else you may be in trouble.
