What is the healthy amount of body fat to have?

I went online to a full body analysis and it told me that my body fat is 20% of my weight. What is the healthy body fat percentage? How can I get at that level? Sources? Here's the link I used. http://health.bizcalcs.com/Calculator.asp?Calc=Full-Body-Analysis I'm a male.

1. The only very accurate way to learn your body fat percentage is to use skin fold caliper tests or to be weighed underwater. 21-33% is the healthy range for women.
2. males are 10-15 percent most healthy, women are 20% (this is so they can give birth) Hope that helps!
3. For women 20-40, the general rule is 20% to 33% body fat is ok. That range increases a bit if you are older than 40. For men 20-40 the healthy range is about 8% to 19%, and again, the range shifts higher with age. This source should be accurate since it's based on WHO and NIH guidelines.
4. Maybe around 20 but I'm not sure. Oh and I'm 12 and my body fat is 30 %
5. I was at about 15 and was told that is pretty ideal, shoot for 10 and lower if you want to see ab definition/muscle definition in general
6. for women it is 27% and for men its 15%.. so.. ure in good shape!! but ive never heard of doing it online. did u have to measure urself? but yay!
7. that is perfect, keep eating healthy and excercising regularly.
8. That online thing is not accurate at all. I use this scale, it sends out little electrical signals to see the thickness of skin/fat on the bottom of your feet. I've compared it to the skin fold test and it is very accurate. I'm a male and at about 13% body fat.
