Energy Expenditure

TITLE PAGE  6: Resting Metabolic Rate

“Basal Metabolic rate accounts for ~70% of daily energy expenditure,  whereas active physical activity contributes 5-10%.  Thus,  a significant component of daily energy consumption is fixed.”
Harrison’s Principles of Internal Medicine 18th Edition, McGraw Hill. Longo et. al. p. 623.

The body can be a miser with calories.  Just as a nickel can be stretched to a quarter, a calorie can be stretched and saved quickly as fat.  The energy expenditure that decreases in terms of the basal metabolic rate when the reduced obese state is achieved can not be compensated by extra exercise as exercise metabolism is also reduced by 42%.
