Document Summary

Fnn module 11 energy balance & healthy weights. Energy balance energy in vs. energy out. Basal energy expenditure & basal metabolic rate. What is needed to keep us alive - in a very vegetative state. Bmr is measured with many factors and rules to follow (fasting, no exercise, etc. : direct and indirect calorimetry and is expressed as basal energy expenditure (bee, varies on age, size, gender and physiological state. Can use direct/indirect calorimetry but most often estimated with predictive equations. Basal/resting metabolic rate + activity + thermic effect of food. Metabolic cost of external work and is the most variable part. Planned physical activity: time, exertion, body size. Non-exercise activity thermogenesis (neat: every day to day activity we do other than sleeping, eating, and sports like exercise, aka activities of daily living. The energy required for the digestion of food and the absorption, metabolism, and storage of nutrients.
