Document Summary

Calories that you get from food: even with some decreased calorie intake, weight is still growing, 3 components of energy balance: decreased calorie intake, increased physical activity, and behavior modification, energy balance: Energy input = energy output = energy balance. Energy input > energy output = positive energy balance. Energy input < energy output = negative energy balance. Energy measurement: basal metabolism (bmr): the minimal amount of calories expended in a fasting state to keep resting, awake body alive in a warm, quiet environment. Accounts for 60-75% of total energy used by the body: resting metabolism (rmr > bmr): amount of calories the body uses when the person has not eaten in 4 hours. Factors influencing bmr: lean body mass, larger body surface area, male gender, body temp, thyroid hormone, stress, pregnancy, caffeine and tobacco use. Which one has the greatest influence on bmr: lean body mass.
