I wondered about the scientific basis behind those popular body fat monitor scales, such as the Tanita series. Scales like those can show your body fat percentage, along with your body weight, which is remarkable. So a little research into their accuracy yielded the following references. It’s boring to most people, but interesting to a few, who really want to know.

|Very Interesting. Weight loss increases mortality rates, but
Fat Loss lowers mortality rates.

This page is an index, of body fat related articles pertaining to weigh scales. I made it long ago, and I’ll admit the reason was, I wanted people to be able to find my webpages with search engines, and there was a theory back then, that having a lot of pages on a topic, gave an indication that the whole website had some expertise on the topic. Well, its 2015 now when I’m adding this paragraph, and that theory has changed a lot. Now, small numerous pages of thin content can hurt the whole website, so I don’t really know what to do. I decided to leave these pages on my site, even though they are lame when it comes to fat and measuring body weight. But not every good idea comes along instantly when you need. I think I’ll wait for an inspiration to improve this whole area of my content.
