Body Mass Index (BMI) Calculator

Your body mass index (BMI) is the percentage of body fat you carry.  Improving your fitness through cardio exercise and strength training can help reduce your body fat as well as your risk for certain illnesses such as high blood pressure, heart attack, stroke, high cholesterol and diabetes.

Your BMI is based on your weight and height.  This calculator provides an estimate, but is not 100% accurate since it cannot account for muscle mass, bone density and other factors outside of your weight and height.  

Use the BMI calculator to get an idea of how much body fat you have.  This can be used to set goals for weight loss or improving your health.  This can also be used to monitor your progress as you diet and exercise.  

Use the body fat percentage chart to see if you need to lose weight, gain weight, adjust your goals, or if you are on the right track.  

So you understand how much body fat you have, now you need to figure out how to get rid of it.  The only way to lose weight is to create a calorie deficit.  This is done by eating fewer calories, burning more calories through exercises or both.  Therefore, you need to know how many calories you are eating and how many calories you are burning through exercise.  Use the calorie counter to find out how many calories are in your diet and the calories burned calculator to discover how many calories you can burn doing some basic exercises.  

So how many calories should you burn/cut to create a calorie deficit?  Calculating your basal metabolic rate (BMR) will help you find out how many calories you need at rest, and this can be your starting point for determining if you are eating too many calories, as well as how many you should cut/burn to lose weight.  Remember, one pound of fat is equal to 3,500 calories.  So for every 3,500 calories you cut and burn, you will lose a pound.  Reducing your calories by 500 a day will help you safely lose about a pound a week.

But losing weight shouldn't be your only goal.  Changing your body composition from fat to muscle is key in a lean body.  Protein is the building block for creating lean body mass, and eating the right amount of protein will help you develop muscle while reducing fat.  Since everyone's protein needs are different, it is best to use the protein calculator to find out how much protein you should be consuming everyday.
