Calculating How Many Calories You Need

Presentation transcript:

Metabolism Living cells use nutrients in many chemical reactions that provide energy for vital processes and activities

Metabolisms function Homeostasis: a healthy and relatively constant internal environment Body regulates to avoid dangerous lacks or excesses

Chemical Balance Body needs the right balance of nutrients and other substances dissolved in the blood and cells Oxygen Temperature Removal of waste products

Energy for Metabolism During metabolism, energy is both used and produced

Food Sources of Energy Carbohydrates Fats Protein

Metabolic Rate How fast the chemical process of metabolism takes place

Body temperature Changes in body temperature Shiver=increased body heat=relatively constant metabolic rate Metabolic processes release energy, in hot climates the metabolic rate slows to help cool the body

Body Size Metabolic rate matches body size

Physical Development and Age Cells function rapidly in young individuals in order to build the new material needed for development

Body Composition Lean tissue takes more calories to maintain than other types

Energy Supply Low energy = slower metabolism

Basal Metabolism Energy used by a body at rest to maintain automatic, life-supporting processes

Basal Metabolic Rate (BMR) A measure of heat given off per time unit, usually as Kcalories per hour

Voluntary Activities Conscious and deliberate actions

Weight-Loss Diets Very low-kcalorie “crash” diets are not the best way to lose weight

Physical Exercise Exercise increased metabolism Toned muscles burn more calories

Metabolic Rate Calculate your Metabolic Rate Men: 66+(6.23 X wt in pounds) + (12.7 X ht in inches) – (6.76 X age in years) Women: 655 + (4.35 X wt in pounds) + (4.7 X ht in inches) – (4.7 X age in years)
