  • What is the formula for calculating BMI?

    BMI = weight (kg) / [height (m)]²
  • Body Mass Index (BMI)

    A common, inexpensive tool for assessing weight-related health risk using weight and height.
  • What BMI range is considered 'healthy weight'?

    18.5 to 24.9
  • Underweight BMI

    BMI less than 18.5
  • What is a limitation of BMI?

    It does not account for lean body mass versus fat mass.
  • Obese BMI

    BMI of 30 or higher
  • Body Composition

    The relative amounts of lean body mass and fat mass in the body.
  • What is lean body mass?

    Body mass excluding fat; includes muscle, bone, organs, and water.
  • Fat Body Mass

    The total mass of adipose (fat) tissue in the body.
  • What is the ideal fat body mass percentage for males?

    About 2–24% of body mass
  • What is the ideal fat body mass percentage for females?

    About 10–30% of body mass
  • Visceral Fat

    Fat stored around the organs inside the abdominal cavity.
  • What is central obesity?

    Excess fat around the midsection, associated with higher visceral fat.
  • Subcutaneous Fat

    Fat stored under the skin but above the muscle; 'pinchable' fat.
  • What body shape is associated with higher visceral fat?

    Apple-shaped (central obesity)
  • What is the significance of pear-shaped fat distribution?

    More subcutaneous fat, lower central obesity, and lower chronic disease risk.
  • Waist Circumference

    A simple measure of central obesity using a tape measure around the waist.
  • What waist circumference is considered high risk for women?

    Above 35 inches
  • What waist circumference is considered high risk for men?

    Above 40 inches
  • Skin Fold Test

    Uses calipers to measure the thickness of subcutaneous fat at various body sites.
  • What is a limitation of the skin fold test?

    Accuracy depends on the skill of the person performing the test.
  • Bioelectrical Impedance

    Measures body composition by sending a low-level electrical current through the body.
  • What factors can affect the accuracy of bioelectrical impedance?

    Hydration status, recent food intake, exercise, and alcohol consumption.
  • Underwater Weighing

    Measures body composition by comparing body weight in and out of water.
  • What is a con of underwater weighing?

    Requires specialized equipment and comfort in water.
  • Air Displacement Pod

    Assesses body composition by measuring air displacement in a sealed chamber.
  • Dual X-ray Absorptiometry (DXA)

    Uses low-level x-rays to differentiate between bone, lean tissue, and fat.
  • What is a major advantage of DXA?

    Provides accurate body composition and bone density measurements.
  • Why is combining BMI and waist circumference useful?

    Together, they provide a better assessment of disease risk than either alone.
