1 CC Not only the lack of exercise

2 Sedentary Behavior and Inactivity Physiology Killing you softly and gently

3 A distinct class of behaviors (e.g., sitting, watching TV, driving) characterized by little physical movement and low energy expenditure ( Less/equal to 1.5 METs) Appl. Physiol. Nutr. Metab. 35: 725–740 (2010)

4 This is the result of the “active day”

5 Total Energy Expenditure For The Day 0 Kcal/day 2000 Kcal/day 1000 Kcal/day Basal Metabolic Rate Activity Thermogenesis Thermal effect of food

6 More detailed! 0 Kcal/day 2000 Kcal/day 1000 Kcal/day Non Exercise Activity Thermogenesis (NEAT) Exercise
