Obese people generally burn more calories than lean people doing the same activity. c. Activities like walking or cycling burn calories but are not the best activities for increasing lean musle mass. d.

Which of the following food sources of macronutrients does NOT provide 4 kcal per gram (if all the water were removed). a. starch b. Sugars c. Amino Acids d. Vodka 1 points QUESTION 3 Which of the following is NOT true about direct calorimetry. a. Measurement of heat production is the direct measurement of energy production. b. The amount of Oxygen consumed and the CO2 produced is measured. c. A bomb calorimeter uses water to capture heat from burned food d. When fat is burned in a direct calorimeter it will raise the water temperature over twice as much as when carbohydrate is burned. e. Fermentable and non-fermentable fiber will produce the same amount of energy in a calorimeter although they don’t provide the same amount of energy to the body. TEF is the energy used for… a. Digesting food b. Absorbing food c. Metabolizing food d. All of the above Which of the following is NOT true about nutrient utilization. a. Dietary fat is oxidized for energy within a few hours of being consumed at a meal. b. Dietary carbohdyrate is oxidized for energy within a few hours of being consumed at a meal. c. Dietary protein that is not used for protein synthesis is oxidized for energy within a few hours of being consumed at a meal. d. Dietary alcohol is oxidized for energy within a few hours of being consumed, provided that it is not consumed faster than the liver can process it. QUESTION 4 If Energy In is greater than BMR + TEF + PA then… a. BMR will automatically increase to burn more calories b. TEF will shift from 5 to 15% of energy intake. c. PA will decrease, causing an energy excess. d. The extra kcal will go into storage as body fat. 1 points QUESTION 5 Which of the following is true about the interrelationship between genetics and environment on the development of obesity. a. Most people who are obese have a genetically slow metabolism. b. A given individual will have more or less genetic tendancy toward obesity, but it is still necessary to consume more calories than you burn in order to store fat. c.
