Document Summary
The amount consumed vs the amount expended. 500 kcal to lose 1 lb per week. Weight loss plateaus as energy deficit increases. Kcal deficit is larger for women and obese. Lean tissue (muscle protein and bone mineral) 25% During starvation fat loss and lean loss is equal. Bomb calorimeter: finds how many kcal a food provides. Food is burned and releases energy as heat which is used to find the energy value. Reaction also makes co2 and h2o where the amount of o consumed gives indirect measure of the amount of released energy. Overstates the physiological fuel value (amt of energy the body derives from food) Bodies cant metabolize all energy yielding nutrients at once. Energy can also be computed from the amt of carbs, fat and proteins. Appetite makes a person eat (or not eat) Response to the sight, smell, thought or taste of food.
