Presentation Transcript

  1. Respiratory Quotient

  2. Carbohydrate RQ= 1.0 • Fat RQ < 1.0 ~ 0.7 • Protein RQ <1.0 ~ 0.8 • Usual mixed diet RQ ~ 0.85 • Diet of 40% CHO & 60% Fat RQ ~ 0.82 Substrate RQ

  3. RQ <0.8 – Patient may be underfed • RQ <0.7 – Starvation, low CHO diet, heavy alcohol consumption. • RQ > 1.0 – hyperventalation, acidosis Clinical Applications

  4. Spirometer

  5. If RQ is equal to 1, we can determine that the body it utilizing 100% CHO for energy • If RQ is 0.7, we can determine that the body is using 100% fat for energy. • Usually values fall in between. Early in exercise the body uses CHO for fuel, as activity increases fat is utilized. Energy Expenditure

  6. High fats diets for the elderly or patients suffering from COPD • High CHO diets for athletes Nutrition Applications
