Lesson 3

• Can be found in muscle tissues, under the skin or around the organ.

  Body Fat
• Helps shield internal organs, stocks fuel for energy, and controls important body hormones.

  Essential Body Fat
• Two Kind of Body Fat:

  1. Body fat
  2. Storage Body fat
• Is a combination of fat and tissues in your body.

  Body Composition
• Also known as lean tissue, includes bone, water, muscle, organ, and tissue. Lean tissues are “metabolically active, burning calories for energy, while body fat is not.” (Scott, 2018).

  Storage Body Fat
• Factors Affecting Body Composition

  1. Age
  2. Sex
  3. Genes
  4. Hormones
• Is a body composition indicator that reflects how much bodyweight is fat. The percentage of the body that is not fat is called lean mass.

  Body Fat Percentage (BFP)
• Methods of Measuring Body Fat Percentage (BFP):

  1. Skinfold measurement
  2. Calipers
• • Is both accurate and practical for measuring body fat.
  • Is a preferred method of measuring body fat in non-clinical settings since it is simple to use, has established accuracy, and is not intrusive to the patient.

  Skinfold measurement
• • Are used to measure the thickness of skinfolds in millimeters in areas where fat typically accumulates (i.e., abdomen, hip, arm, back, and thigh).

  Calipers
• • Is a value derived from the mass (weight) and height of a person.
  • Is just a weight-to-height ratio.
  • It is a method for determining adults’ weight status and general health in big populations

  Body Mass Index (BMI)
• BMI=


  $Weight(kg)/Height(m)^2$
• Classifications:

  • Below 16.0 - Severely Underweight
  • 16.0-18.5 - Underweight
  • 18.5-25 - Normal
  • 25-30 - Overweight
  • 30-35 and above - Obese
• • Is the energy needed to raise the temperature of 1 kilogram of water through 1ºC, equal to one thousand small and often used to measure the energy value of foods.
  • The amount of energy in the foods and beverages you eat and drink is measured by your intake.
