energy intake

• How do you calculate energy expenditure


  BMR + TEF + expenditure during physical activity
• What is BMR


  Basal metabolic rate

  
  

  minimum amount of energy required to sustain function at rest
• What is TEF


  Thermic affect of food

  
  

  energy required to eat, digest and absorb food
• What are used to calculate physical activity expenditure


  Metabolic equivalent values (MET)
• What is energy intake

  Amount of energy from food and drinks (J or kcal)
• What is energy balance


  the relationship between energy intake and energy expenditure
• Weight loss =


  energy expenditure more than intake
• energy intake more than expenditure

  weight gain
• energy intake same as expenditure

  weight maintained
