BIOL 108 Lecture Notes - Lecture 99: Lactose Intolerance, Energy Density, Negative Energy
Document Summary
To improve one"s energy balance, one can consider: energy values of nutrients: these are the average physico-chemically determined energy values for the macronutrient classes (and alcohol, which is not considered a nutrient it"s actually a toxin but does provide kcals). The actual amount of usable energy the body derives from these nutrient classes may be less (physiological energy values). Fiber 0 kcal/g: energy density of foods. Actual foods also differ in the quantity of energy they contain per unit of weight. Low energy density foods (e. g. steamed vegetables) fill you up and induce satiation sooner than high energy density foods (e. g. ice cream). A person"s daily energy budget consists of these categories of energy use: The energy used for breathing, heartbeat and biochemistry while one is completely at rest. Usually the largest part of one"s energy budget, 50-65%. Energy used for activity beyond basal metabolism ranges all the way from just sitting or standing up to running marathons.
