Add Tracking for Body Fat Percentage

[KaladinRand]

Add ability to track body fat percentage alongside weight. Data could interact to show fat mass and lean mass trends.

Seeing my fat mass continue to drop while gaining muscle weight is really helpful in keeping me motivated even when the scale isn't moving much.

Thanks!

I would also like to be able to add body fat percentage, total body water and muscle from my smart scale.

To add to this request: add an option to track body fat using caliper methods (there are 5 main ones). The calculations for the different methods are freely available (see this article).

Body fat percentage calculations based on BMI are notoriously inaccurate, especially if you fall into body type categories outside the standard deviation.
