Here is a collection of visual body fat charts. Use these to estimate your personal body fat for the keto calculator. See below for men.
As you can see, even the same body fat percentag (here twice 15%) can look quite different, depending on your muscles and where the body fat is positioned. The minimum possible body fat percentage is 8-9%. This low is not sustainable, and very unhealthy! If you are female, don’t go that low.
As above with the female pictures, here are also two images with the same body fat percentage: 10% can look quite different, depending on how muscular you are and where your body fat is positioned. The lowest male can go os 3-4%, but this is not at all healthy at all. It is only possible to reach such low body fat for a very short period of time. I’d say the lowest you should go to still be healthy is 10%.
