The studies in progress will also show whether a combined approach US SAT measurements and anthropometric indices like W will improve the assessment accuracy.

Standardized fat levels -

In most people, LDL cholesterol makes plaque in the arteries. A one-percent reduction of saturated fat in your diet reduces your heart disease risk by three percent. Keep saturated fat to less then 15 grams per day. It is not required to list unsaturated fats polyunsaturated and monounsaturated on food labels.

In general, unsaturated fats lower cholesterol. The healthiest unsaturated fat is canola oil. Look at the ingredients to see what type of fat was used to make the food. Many processed foods contain partially hydrogenated oils, which are called "trans fatty acids. However, they are not considered part of the saturated fat grams on the nutrition facts panel.

Limit foods containing these fats, especially if they are listed as one of the first few ingredients. Your total cholesterol intake should be less than mg. per day. One of the major sources of cholesterol in the diet is animal products.

Many fresh meats, poultry and fish do not have a nutrition facts label. The average cholesterol per ounce of an animal product is 25 mg. Divide the calories from fat by the total calories. Keep in mind not every food you eat needs to contain less than 30 percent of the calories from fat.

Some foods will contain no fat, such as fruit, and others may contain a higher percentage. It's the average of all the foods in your diet that you want to keep to less than 30 percent.

Too much sodium in your diet can contribute to high blood pressure, a major risk factor for heart disease and stroke. Kidney disease and osteoporosis are also associated with a high sodium diet.

The average American eats 5,, mg. of sodium per day. Most of this comes from processed foods. Our bodies need about mg. per day to function. You can reduce the sodium in your diet a lot by eating fresh foods rather than foods in bags, boxes and cans. Most government and health organizations suggest a limit of 1,, mg.

When it comes to sodium, less is best. Carbohydrates are the main source of energy during most physical activity. Carbohydrates should comprise percent of your calories, or about grams per day depending on your caloric requirement.

Fiber may play as much of a role in disease prevention as fat. The CDC BMI-for-age growth charts take into account these differences and visually show BMI as a percentile ranking. These percentiles were determined using representative data of the US population of 2- to year-olds that was collected in various surveys from to Obesity among 2- to year-olds is defined as a BMI at or above the 95 th percentile of children of the same age and sex in this to reference population.

For example, a year-old boy of average height 56 inches who weighs pounds would have a BMI of For more information and to access the CDC Growth Charts. For adults, the interpretation of BMI does not depend on sex or age. Read more about interpreting adult BMI. The correlation between the BMI and body fatness is fairly strong 1,2,3,7 , but even if two people have the same BMI, their level of body fatness may differ The accuracy of BMI as an indicator of body fatness also appears to be higher in persons with higher levels of BMI and body fatness While, a person with a very high BMI e.

According to the BMI weight status categories, anyone with a BMI between 25 and However, athletes may have a high BMI because of increased muscularity rather than increased body fatness.

In general, a person who has a high BMI is likely to have body fatness and would be considered to be overweight or obese, but this may not apply to athletes. People who have obesity are at increased risk for many diseases and health conditions, including the following: 10, 17, For more information about these and other health problems associated with obesity, visit Health Effects.

Obesity, defined as an excessive amount of body fat, is a common and expensive medical condition in the U. Obesity, or body fatness, is calculated with various methods that range in accuracy and have limitations. Combining two or more methods, if possible, may better predict if someone has increased health risks related to weight.

One of the most widely used tools for estimating excess fat is the body mass index BMI. In comparison with these methods that require expensive equipment, BMI is noninvasive, easy to calculate, and can be used anywhere.

Because of its simplicity and widespread use, BMI is often used when studying populations. Researchers can compare the BMI of groups of people over time in different areas, to screen for obesity and its related health risks.

BMI does have several limitations. For these reasons, BMI might be used as a screening tool for potential weight-related problems rather than to diagnose certain conditions.

The accuracy of BMI in predicting health risk may vary across different individuals and racial and ethnic groups. Some populations have higher rates of obesity but that do not have corresponding rates of metabolic diseases like diabetes, and vice versa. BMI might be supplemented with other measures such as waist circumference or waist-hip ratio that better assess fat distribution.

When examining the relationship between BMI and mortality, failure to adjust for these variables can lead to reverse causation where a low body weight is the result of underlying illness, rather than the cause or confounding by smoking because smokers tend to weigh less than non-smokers and have much higher mortality rates.

Experts say these methodological flaws have led to paradoxical, misleading results that suggest a survival advantage to being overweight. Some researchers consider waist circumference to be a better measure of unhealthy body fat than BMI as it addresses visceral abdominal fat, which is associated with metabolic problems, inflammation, and insulin resistance.

In people who do not have overweight, increasing waist size over time may be an even more telling warning sign of increased health risks than BMI alone. Wear thin clothing or no clothing. Stand up straight and wrap a flexible measuring tape around your midsection, laying the tape flat so it crosses your navel belly button.

The tape should be snug but not pinched too tightly around the waist. You can repeat the measurement times to ensure a consistent reading.

According to an expert panel convened by the National Institutes of Health, a waist size larger than 40 inches for men and 35 inches for women increases the chances of developing heart disease, cancer, or other chronic diseases.

Like the waist circumference, the waist-to-hip ratio WHR is used to measure abdominal obesity. It is inexpensive and simple to use, and a good predictor of disease risk and early mortality.

Some believe that WHR may be a better indicator of risk than waist circumference alone, as waist size can vary based on body frame size, but a large study found that waist circumference and WHR were equally effective at predicting risk of death from heart disease, cancer, or any cause.

The World Health Organization has also found that cut-off points that define health risks may vary by ethnicity. For example, Asians appear to show higher metabolic risk when carrying higher body fat at a lower BMI; therefore the cut-off value for a healthy WHR in Asian women is 0.

Stand up straight and follow the directions for measuring waist circumference. Then wrap the tape measure around the widest part of the buttocks.

Divide the waist size by the hip size. The WHO defines abdominal obesity in men as a WHR more than 0. Waist-to-height ratio WHtR is a simple, inexpensive screening tool that measures visceral abdominal fat. It has been supported by research to predict cardiometabolic risk factors such as hypertension, and early death, even when BMI falls within a healthy range.

To determine WHtR, divide waist circumference in inches by height in inches. A measurement of 0. Equations are used to predict body fat percentage based on these measurements. It is inexpensive and convenient, but accuracy depends on the skill and training of the measurer. At least three measurements are needed from different body parts.

The calipers have a limited range and therefore may not accurately measure persons with obesity or those whose skinfold thickness exceeds the width of the caliper. BIA equipment sends a small, imperceptible, safe electric current through the body, measuring the resistance.

The current faces more resistance passing through body fat than it does passing through lean body mass and water. Equations are used to estimate body fat percentage and fat-free mass.

Readings may also not be as accurate in individuals with a BMI of 35 or higher. Individuals are weighed on dry land and then again while submerged in a water tank. This method is accurate but costly and typically only used in a research setting. It can cause discomfort as individuals must completely submerge under water including the head, and then exhale completely before obtaining the reading.

This method uses a similar principle to underwater weighing but can be done in the air instead of in water. It is expensive but accurate, quick, and comfortable for those who prefer not to be submerged in water. Individuals drink isotope-labeled water and give body fluid samples. Researchers analyze these samples for isotope levels, which are then used to calculate total body water, fat-free body mass, and in turn, body fat mass.

X-ray beams pass through different body tissues at different rates. DEXA uses two low-level X-ray beams to develop estimates of fat-free mass, fat mass, and bone mineral density.

It cannot distinguish between subcutaneous and visceral fat, cannot be used in persons sensitive to radiation e. These two imaging techniques are now considered to be the most accurate methods for measuring tissue, organ, and whole-body fat mass as well as lean muscle mass and bone mass.

However, CT and MRI scans are typically used only in research settings because the equipment is extremely expensive and cannot be moved.

Essential body fat is necessary to maintain life and reproductive functions. The percentage of essential body fat for women is greater than that for men, due to the demands of childbearing and other hormonal functions. Storage body fat consists of fat accumulation in adipose tissuepart of which protects internal organs in the chest and abdomen. A number of methods are available for determining body fat percentage, such as measurement with calipers or through the use of bioelectrical impedance analysis. The body fat percentage is a measure of fitness level, since it is the only body measurement which directly calculates a person's relative body composition without regard to height or weight.
