About how many pounds (lbs) is 10% of body fat?

depends on how much body fat you have. If you need help plugging in the numbers, drop me a funmail and I'll help you. xox Sika

A. First determine your body mass index, a ratio of weight to height. It's tricky, so follow this example of a 145 pound, 26-year-old woman who's 5'10' (70 inches).

Example: 70 x 70 = 4,900

Divide your weight by that number.
Example: 145/4,900 = .029

Multiply that by 703 to find your BMI.
Example: BMI = .029 x 703 = 20.39

B. Determine your body fat percentage.

Example: 1.20 x 20.39 = 24.46

Then multiply your age by .23.
Example: .23 x 26 = 5.98

Example: 24.46 + 5.98 = 30.44

Subtract 5.4 from that number to find your body fat percentage.
Example: 30.44 - 5.4 = 25.04

C. Use the chart below to determine how far over the goal you are (or aren't!). At 25 percent body fat, our sample woman is carrying 14 percent more fat than the ideal of 21 percent.

Body Fat - Percent over Goal (for Funadvice I'm only going to 50%)
21 - 0%
22 - 4%
23 - 7%
24 - 11%
25 - 14%
26 - 18%
27- 21%
28 - 25%
29 - 29%
30 - 32%
31 - 36%
32 - 39%
33 - 43%
34 - 46%
35 - 50%

D. Translate your body fat percentage into how much shear fat you're carrying around by multiplying your body fat by your current weight.
Example: (145 x 25%) = 36.25,
meaning 36.25 pounds of our 145 pound woman comes from fat.

(then from here you can figure out what 10% of your body fat is by moving the decimal. 10% of 36.25 lbs is 3.625 pounds... so a little over 3 1/2 pounds.)

E. Finally, multiply your percentage over goal from C by your total body fat answer in D. That's how many pounds of fat you should seek to lose.
Example: 36 x 14% = 5.14 pounds.
