There is no 'average' height and weight for a 20-year-old woman. Weight is related to height and body composition rather than age. In addition, height tends to relate to nationality rather than age. For more information about the heights of women worldwide, and weight in relation to body composition, please see the page links, further down this page, listed under Related Questions.

The BMI (Body Mass Index) charts are used to find where your height and weight intersect on the chart to indicate your BMI. Or you can use this easy calculator on the Centers for Disease Control and Prevention (CDC) site, where you can also find more information on why the BMI calculations are useful. (see link to site below).

Generally, if someone has a BMI of 20, he/she usually has a substantial fat layer under the skin. As such, the fat layer will tend to "smooth" over the usual muscle definition, and you won't really be able to see what your abs look like. You need to get down to 10 or even lower to show your abs.

A healthy Body Mass Index for people of any age or gender is considered to be 18.5 to 25. BI is calculated using a person's weight and height. Age is not considered.

* Men can weigh 71.2 - 76.2 kgs * Women can weigh 67.1 - 71.7 kgs * But if your body fat is less than 10% - then you can weigh a bit more * For a female, between about 140 - 170 lbs, for a man about 145 - 185 lbs. For more information, see the related question further down this page.

A BMI Number Between 19 and 25 Is Considered Normal. To Get Your BMI Number Take You Weight In Kilograms Divided By Your Height In Meters Squares KG/M squared.

Well, I'm 12 years old and I'm 5'6 and 90 pounds... my bust is 30inches, my waste is 23 inches, and my hips are 31 inches... my wrists are 2 inches my angles are 6.5 inches, and my this are 15, my calfs are 11, my shoe size is 6 and my inseam is 31

Depends on your age. Under 16, about 1300-1800 calories a day, I'd wager.. over 18, around 1800-2000. It depends on your metabolism/activity level, as well.. the more you work out/move, the more calories you need to eat.

Phelps (Olympic swimmer) burns something like 25,000 calories a day.. so he needs to eat that much, and maybe a little more, to maintain his body weight. The average person doesn't need to eat more than 2,000 calories a day.

mine is 12. i heard that pretty low. the low range is probably 5 (in rare cases) to 15

It's impossible to tell because the BMI test isn't accurate below 18 years old. However I suggest you check this website. Special:Search

Breakfast is a very important meal, as it is your body's first chance to produce energy after a night of sleep. If you skip breakfast, you may encounter irritability or low levels of concentration due to hunger. If you skip breakfast regularly, your body will adapt by slowing down metabolism in order to preserve energy throughout the morning.

Use your BMI or Body Mass Index. The equation is:

BMI = 704 x weight (in lbs)/height in inches squared

So, that's BMI = 704 times your weight in pounds, divided by your height in inches squared

A healthy number is between 19 and 25.

Fat hangs and wobbles. Muscle is tight and hard. You can get a BMI chart from either your doctor or on line. It will ask you a few numbers about yourself and you got to divide and multiply and you will come out with your BODY MASS INDEX which measures the percentage of fat on your body.

Please don't search your answers here for Primavera. Use your reading materials provided. A certain amount of body fat is necessary, as it regulates body temperature, cushions internal organs, helps with shock absorption during exercise and stores caloric energy. According to the American Council on Exercise, between 10 to 13 percent body fat is essential for women. Other classifications include athletic, or 14 to 20 percent; fitness, 21 to 24 percent; and average, 25 to 31 percent. Essential fat is the bare minimum needed for bodily function.

Lean body weight refers to the sum of the weight of your bones, muscles and organs

Well my bf weighs 107 and he is 5'5" and 13, but he also has muscles, like a 4 pack so that will give weight! But he is in excellent shape. So if you weigh 107 or less and your 5'5" 13 year old boy, than you have an amazing body! :)
