Body Mass Index (BMI) = Kg/m2 (Weight in Kilograms / Surface Area in Square Meters)
BMI or Body Mass Index correlates closely with body fat content. This calculation does not differentiate weight of muscles from the weight of fat nor the weight of bones. Very muscular men and women may have a falsely high BMI. Those individuals with heavy bone framework will also have a high BMI.
BMI also may not accurately reflect body fatness in people who are very short (under 5 feet) and in older people, who tend to lose muscle mass as they age. But for most people, BMI is a reliable way to tell if your weight is putting your health at risk.
The higher the BMI, the greater the risk of developing additional health problems. Please remember that since body mass index doesn't actually measure body fat, it is possible to be 'overweight' but not really obese. People who are very muscular might have a high BMI and be classified as overweight, even though they aren't 'fat.'

Plastic Surgery is Not an Alternative to Losing Weight
Plastic surgery is better reserved for after weight loss. Losing weight is a coarse tool. You cannot pick where the weight comes from, or when added, goes onto. Plastic Surgery is better uses as a refinement tool. Dr. Bermant as a surgical sculpture prefers to let the coarse tool shape the body first and then help with refinement using Plastic Surgery Sculpture. During weight loss, Body Shaper Compression Garments can contour and shape evolving tissues until they stabilize for surgery.
Medical Conditions Related to Obesity (often stabilized or cured with losing weight)
Bariatric Surgery and Weight Loss Surgery
Bariatric Surgery is the name for a group of surgical options for weight loss, changing the way food passes through the body. This is not trivial surgery and those interested in Bariatric options should spend time learning about risks and limitations.
Indications for Bariatric Surgery and Weight Loss Operations
- More than 100 pounds overweight
- Twice the ideal weight
- BMI 40 or greater
- BMI between 35 and 40 if there are significant medical conditions related to obesity
Waist Measurement Also a Tool to Determine Risks
Like BMI, location of fat is also a risk factor for your health. If your fat is mainly around your waist, you are at higher risk for health problems than if your fat is mainly on your hips and thighs. Fat about the center of the body is a factor even with a normal BMI.
Measure Waist Circumference
To measure the circumference of your waist, use a cloth measuring tape around your bare stomach just above your iliac crest (hip bone). The tape should be parallel to the floor and snug, but not compressing the skin. Relax your muscles, exhale and measure your waist.
Waist measurements of over 35 inches (88.9 cm) in a woman or 40 inches (101.6 cm) in men may have a higher risk of medical problems than those with smaller waists.
If you are unable to use the BMI calculator, or if you are interested in how BMI is calculated, this section has the mathematical formulas. You can calculate BMI using either feet, inches, and pounds, or meters, centimeters, and kilograms.
Body Mass Index can be calculated using pounds and inches with this equation
BMI = (
|Weight in Pounds||
) x 703
|(Height in inches) x (Height in inches)|
For example, a person who weighs 200 pounds and is 6 feet 1 inches tall has a BMI of 26.4.
|(||200||) x 703 = 26.4|
|(73) x (73)|
Body Mass Index can also be calculated using kilograms and meters (or centimeters).
|Weight in Kilograms|
|(Height in Meters) x (Height in Meters)|
BMI = (
|Weight in Kilograms||
) x 10,000
|(Height in centimeters) x (Height in centimeters)|
For example, a person who weighs 70 Kilograms and is 1.765 Meters (176.50 centimeters) tall has a BMI of 22.5.
|(||70||) = 22.5|
|(1.765 m) x (1.765 m)|
