Basal Metabolic Rate Calorie Calculator

Basal metabolic rate, and the closely related resting metabolic rate, is the rate of energy expenditure by humans and other animals at rest, and is measured in kJ per hour per kg body mass. This calculator may require knowledge you do not know without visiting a Nutritionist, or Doctor. Succeed in accomplishing your goals visit a Doctor, or Nutritionist in your Area.

Body Composition

Your body is made up of water, fat, protein, carbohydrate and various vitamins and minerals. There are correlations between the ratio of water and muscle mass that do not vary greatly from person to person, however, the amout of body fat a person has can vary quite greatly. Scientific research has also shown that the percentage of body fat a person has can be a predictor of serious disease and even potentially earlier death.

If you have too much fat — especially if a lot of it is at your waist — you’re at higher risk for such health problems as high blood pressure, high blood cholesterol and diabetes. Abdominal fat increases your risk for heart diseases and stroke. Viseral fat – fat stored around your vital organs can also have an impact on your health.

Obesity is now recognized as a major, independent risk factor for heart disease. If you’re overweight or obese, you can reduce your risk for heart disease by successfully losing weight and keeping it off. Losing even ten percent of your excess weight can begin to make a statistically relevant difference.

Waist circumference and body mass index (BMI) are often used as ways to assess your body composition. Waist-to-hip ratio (WHR) is another index of body fat distribution. WHR is less accurate in predicting the percentage of body fat, than BMI or waist circumference and is no longer recommended. It also seems there is increasing evidence that waist size is more important, as statistics stack up worse for people who carry more of their excess weight on their abdomen than for those who carry more of their excess weight on their hips.

Check your Body Mass Index using our BMI Calculator for adults.

Your goal for waist circumference is less than 40 inches if you’re a man and less than 35 inches if you’re a woman.

Body mass index assesses your body weight relative to height. It’s a useful for measuring body composition because it correlates highly with body fat in most people. Weight in kilograms is divided by height in meters squared (kg/m2). In studies by the National Center for Health Statistics,

  • BMI values less than 18.5 kg/m² are considered underweight.
  • BMI values from 18.5 kg/m² to 24.9 kg/m² are healthy.
  • Overweight is defined as a body mass index of 25.0 to less than 30.0 kg/m².
  • A BMI of about 25 kg/m2 corresponds to about 10 percent over ideal body weight.

As soon as a persons BMIs is more than 10% over the ideal they are at an increased risk of heart and blood vessel disease.
Obesity is defined as a BMI of 30.0 kg/m² or greater which is about 30 pounds or more overweight.
People with BMIs of 30 kg/m² or more are at much higher risk of cardiovascular diseases. There is also a higher risk of Type II Diabetes, and increased likelihood of problems with knees, hips and backs, especially as people age, due to the increased stress on the joints.
Extreme obesity is defined as a BMI of 40 kg/m² or greater.

There are many health risks for people who are extemely obese.

There are some situations where the BMI is not an accurate estimation of body fat. Some well-trained people with dense muscle mass may have a high BMI score but very little body fat. For them skin fold tests can be more effective.

To calculate your exact BMI value, multiply your weight in pounds by 703, divide by your height in inches, then divide again by your height in inches.
