Read through your own question again - do you think it makes any sense? How can you ask a question like that? You can't measure body fat in such values, and the whole idea is just amateur. Anyway, if you're overweight and looking to lose some weight, you can try opting for a weight loss procedure that works, as good weight loss procedures have a combination of exercise techniques coupled with a diet. Reduce your overall fat intake, and ensure that the fats you eat are of the good kind and not of the bad kind. Have unsaturated fats and a lot of fiber and lose weight in this way, rather than trying to calculate your body's fat value.
