One Pinch Fat Test

Is your weight loss or gain muscle or fat? With practice this test takes less than ten seconds. And you can do it every day.

Two of the same test here, allow you to change inputs (measurements, bodyweight, gender) and see what that does to your percent fat and resultant lean and fat mass. This is based on one vertical pinch, taken 1 inch (~2.5cm) immediately to the right* side of your belly button.
