Where can I find information about what official guidelines there are to use to become the healthiest that I can be at my particular age? I say this because I was looking for an average weight for height calculator on the Internet and I have to say that a lot of them were so general that I could not get an “average” after comparing a couple of different numbers. Is there a website somewhere that has official information on exactly what is healthy for me to be weighing at this point in my life and at this age and after having a few children.
