what is my body fat? I am 18, 115 pounds, male?

Answer 1

It is 18% and it should be 9% so get a lot more active.

Answer 2

You can't judge your body fat by your age and weight alone. You also have to factor in your height and bone structure. My best advice would to be get an eletrical impediance scale. When you step on it, it sends a small electric wave through your body. Since muscle has more water than fat it can accurately calculate within 1-5% your body's actual fat percentage. You can find a hand held machine or the scale for about $50-100 at any local health store or wal-mart. The other method is hydro-static weighing where the doctor places you in a tub filled with water and they can somehow detect your exact body fat and this is the most exact method but it also costs a lot of money. So for a fairly accurate result I would settle for 1-5% off of your actual percentage for 3x less the cost of the medical procedure.

Answer 3

With your height you could figure out your BMI (Body Mass Index), but that is not a very good indicator because it doesn't take into account body frame. Clinics, Wellness Centers and such can do a variety of tests to figure it out as well. The tests include:
a skin fold measurement which uses skin calipers (hopefully the person who does this is very good as it can be difficult to get an accurate reading);
hydrostatic weighing (underwater, was considered the gold standard test, but there's some room to wiggle in that too because most people aren't comfortable enough in water to release all of their air and stay under till it can be measured). They can't get exact, which is why they have a residual lung volume place in the formula, but they can get pretty close.
There's a hip to waist ratio measurement that can help identify risk levels. I believe it is your waist in inches divided by your hips in inches, but there is a chart.
Then there's the DEXA Scan, which also scans bone density, but it should be a bit more expensive

If you're at least moderately active and over 5' 3", I would guess between 14-20%, but more towards mid teens since guys tend to sit around that area.

Answer 4

You have to get this measured by someone like at a gym or a doctor's office.

No one can tell you based on age, weight, etc.

Answer 5

IT DEPENDS ON YOUR LEAN BODY MASS... BASICALLY...
HOW MUCH OF THAT 115 IS LEAN TISSUE AND FLUID? THEN THE REST OF THE WEIGHT IS FAT
