Like any form of obesity, lifestyle is the problem.

With modern life meaning parents work long hours and there is not normally a parent at home to cook healthy meals from scratch any more frozen or fast food is becoming a regular meal for many children. Also the abundance of snacks and refined sugar mean children are often getting many more calories than is needed for their weight to stay stable.

The lack of physical exercise also means children are putting on more and more weight. With televisions providing children's shows 24 hours a day children can sit and watch as long as they want. Along side computer games and other modern technology means that children do not spend the same amount of time running around and creating their own games, that they did 10 or 20 years ago.

There is no perfect weight for a 16-year-old girl (or a person of any age). This is because weight is related to height and body composition rather than age. For in-depth information about weight in relation to height, and to see the distribution of weights and heights of children at various ages, and the causes of too much weigh gain, please see the page links, further down this page, listed under Related Questions.

No. BMI takes into account only height and weight, not fatness. As a result, many heavy (yet lean and muscular) athletes would be categorized as obese, even though they have an extremely small amount of body fat. Body fat percentage would be a better factor to consider.

BMI is a measure that is calculated by dividing body mass by the square of the height. The body mass index is easier to calculate by using a BMI calculator

Underweight= <18.5

Normal weight= 18.5-24.9

Overweight= 25-29.9

Obesity= 30+

BMI around 24 is healthy

Work yours out yourself:

BMI = Weight (Kg) / Height (metres)2.

When a lot of your weight isn't fat, so if you're muscly or athletic - but weight machines in places like Boots or in sports clubs often to a percentage body fat measurement, which is more accurate.

BMI is weight/(height*height) in kilograms and metres. 60/(1.68*1.68) = 21.2

This is between 20 and 25 so perfectly normal and healthy for an adult.

Some of this should depend on your measurements and your body fat percentage. What you may find is that as you gain more muscle and less fat, you may appear smaller but actually weigh more. You are actually exactly my size, and I have been a size 0 with less than 10% body weight (competitive swimmer - though really, for a girl this is unhealthy) and a size 7 with some definite jiggle (23% body fat) while maintaining the same weight. With that sizing, your BMI would be 20.7. You can calculate this at http://www.nhlbisupport.com/bmi/. BMI Categories: * Underweight = <18.5 * Normal weight = 18.5-24.9 * Overweight = 25-29.9 * Obesity = BMI of 30 or greater As you can see from the categories, you are completely within the normal and healthy range. I personally have never been a fan of BMI as it doesn't take into account a persons body fat to muscle percentage. You can have this caculated with calipers, via a water displacement test (the most accurate) or with a handheld BMI calulator. These use electrical pulses to guestimate your percentages. They are easily thrown off by the amount of air or water trapped in your system however. The short answer is this: don't worry about the number on the scale, worry about how you feel, how you look (as in how well your muscles are defined and the measurements of your body), and if you choose, your percentages. Just remember we are more than what number we see on the scale. Some of this should depend on your measurements and your body fat percentage.

Yes, it's overwieght. A BMI of 20 is much more desirable and healthy. In terms of "fat," it depends on how the weight is distributed, but it likely is considered fat.

BMI=(weight in lbs*703)/(height in inches^2) (weight in pounds multiplied by 703) divided by (height in inches squared)

Exactly 12 ounces.

A can of soda is just 12 ounces of water with other ingredients dissolved in it.

The clinical limitations of BMI should be considered. BMI is a surrogate measure of body fatness because it is a measure of excess weight rather than excess body fat. Factors such as age, sex, ethnicity, and muscle mass can influence the relationship between BMI and body fat.

Yes, a BMI is considered to be quite thin. A healthy BMI ranges from 18 to 24 in females. A BMI < 18 may be associated with anorexia. Yes, a BMI of 19 is considered to be quite thin. A healthy BMI ranges from 18 to 24 in females. A BMI < 18 may be associated with anorexia.

Hey, I've done a bit of research and this question should help you! The website is: http://www.health.qld.gov.au/patientsafety/pupp/documents/bodymassindex.pdf I hope it helps! Just match it up to your age and body weight

Age is irrelevant in most cases. Height directly corrolates with the avg weight. The calculation is called your Body Mass Index (assuming you are the person in question). The majority of BMI Calculators consider it obese (by a small margin). GRRRR!!!!!!!! im fat!!!

In my area its about 18.6, 19. But if your below about 17 then your underweight.

But if you have been the way you are your whole life and you have a bmi of like 17 then your healthy.

bmi standers dont work that well. I was 17.8 and i was perfectly healthy

Healthy BMI range is same for age group above 20 including both males and females. But, in childrens BMI is age and sex specific which is calculated by using percentile because of difference in amount of fats in different sex and age.

there are many factors that influence weight. there is no set standard but just some guidlands. read the article i send you the link for. it talk about this subject in detail

No. Teenagers have an extremely high metabolism, activity level and are still growing. It's possible that a small female teen with low activity level would need fewer calories than an older, active male, but generally teens need more calories than older adults.

fruits which high in fiber. Pineapple is good it can reduce high blood pressure.
