CC Not only the lack of exercise
Sedentary Behavior and Inactivity Physiology Killing you softly and gently
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)
This is the result of the “active day”
Total Energy Expenditure For The Day 0 Kcal/day 2000 Kcal/day 1000 Kcal/day Basal Metabolic Rate Activity Thermogenesis Thermal effect of food
More detailed! 0 Kcal/day 2000 Kcal/day 1000 Kcal/day Non Exercise Activity Thermogenesis (NEAT) Exercise

PLoS Med 3(12): e488. doi: /journal.pmed Cross sectional study of 1921 children, 9-10 yold and yolds Accelerometer based activity Self reported TV viewing Metabolic risk score TV viewing was NOT correlated with PA (r=0.013, p=0.58)

Evidence for the 4 th tenet Different effects of sedentary behavior compared to “exercise” Metabolic and Mortality effects seen Through age groups Through ethnic groups Newer objective data seems to support larger self reported data
Unpublished Data GlucoseInsulin Breaking news: New data All are statistically significative!
