Here is link for the DXA body composition mentioned by DEXARED.
They don't mention the X-ray dose you surely must get with such a scan. Its the cumulative dose that matters so add many DXA scans and some normal X-rays and high community exposure and it would have a significant risk of cancer effect.

You can do an easy test in the pool. It is a measurement done for scuba diving and I found it really interesting. Go to the deep end in the water. Take a deep breath and then keep your body upright. A "neutral" body will float with the water at eye level. A body with a lot of fat will float with the water below eye level (for me at my mouth). A body with a lot of muscle will float (or not) below eye level. Of course there are lots of factors like water density that can change the results but I was amazed in my class how quickly they decided what weights people needed to be "neutral" in the water. Cost - admission to a pool.

I am disappointed that you made no mention of DXA (dual energy x-ray absorptiometry) in your analysis of the various body composition methods. This is a very easy, quick and precise way to determine fat and lean mass. The person is measured from head to toe and is a very good way to follow weight loss from one time to another visually showing the entire person. None of the other methods show you an image. This is used by many of the most prestigeous universities and research studies in the country. You missed a very important piece to an otherwise very thurough article.

I had been wondering why the hand held bioimpedance machine that we use at worked shows my body fat as 15% or more less than what my scales at home say. I certainly have more fat in the lower half of my body, so if that is all my scales are measuring, of course it would be higher, than a machine that is only testing the fat in my arms. So do I average the two to get a more accurate number of my body fat?!lol
