Document Summary

Energy balance: overweight and obesity among adults. Energy balance: state in which energy intake, in the form of food and or alcohol, matches the energy expended, primarily through basal metabolism and physical activity. Energy imbalance: positive energy balance, energy intake (ei) > energy expended, results in weight gain, negative energy balance, energy intake < energy expended (ee, results in weight loss, calories = energy. Cho, protein, and fat (alcohol) - the 4,4,9,7 kcal/g values have been rounded off and adjusted for digestibility and substances in food (fiber) Side 2: energy output: includes, basal metabolism, physical activity, digestion, absorption and processing of ingested nutrients (thermic effect of food, sum of above three equals total energy expenditure (tee) Basal metabolism (bmr: def: minimum energy needed to keep a resting, awake body alive, 60-70% of the total energy expenditure, includes energy for heartbeat, respiration, body temperature regulation, varies between individuals.
