• BMR


  Basal metabolic rate - the minimum amount of energy required to sustain essential physiological functioning
• Thermic effect of food (TEF)


  The energy required to eat, digest and absorb food
• BMR + Thermic effect of food

  Equals total energy expenditure
• Metabolic equivalent (MET)


  A method of calculating energy expenditure of certain activities
• MET values for activities

  • Volleyball (casual) - 3 METs

  Golf - 4.5 METs

  Dance - 4.8 METs

  Basketball - 8 METs

  Studying - 1.8 METs

  Food preparation - 2.3 METs

  Reading/watching TV - 1.5 METs
• Calculating daily energy expenditure

  Calculate BMR calories burned while sleeping

  2. Calculate additional calories burned from activities using MET values

  3. Add BMR and activity calories to get total daily energy expenditure
• Average daily energy expenditure is 2000-2500 calories for males and 1500-2000 calories for females
• Energy balance


  The relationship between energy intake (calories consumed) and energy expenditure (calories burned)
• If energy intake > energy expenditure

  Weight gain occurs
• If energy intake < energy expenditure

  Weight loss occurs
• If energy intake = energy expenditure

  Weight remains stable
