Q: Explain the differences between hunger and appetite. A: Hunger is the internal drive to find and eat food. It is often experienced as a negative sensation. Appetite is the external drive that encourages us to find and eat food. It is related to pleasant sensations associated with food. Q: If a fudge brownie has 22 grams of carbohydrates, 2 gram of protein and 16 grams of fat. How many calories are in the brownie? A: Carb: 22 x4 =88 Pro:2x4=8 Fat: 16 x 9 =144 88 + 8 + 144 = 240 calories Q: The current recommendation to maintain your body weight is 2000 calories daily. If you are told that you should not consume any more than 61 % of your calories from protein, how many grams of protein should you eat in a day? A: 2000 x .61 = 1220 1220 calories / 4 = 305 grams of protein Q: Name the key hormone that causes a feeling of satiety. Indicate where in the body it is produced and the process by which it operates. A: Leptin is produced by the fat cells which are also known as adipose tissue. The role of leptin is to alert the brain to turn off the hunger center and activate the satiety center when consuming a meal. Q: Describe in detail the role that the hypothalamus plays in determining whether or not you feel like eating. A: When we have not eaten for a period of time, the amount of nutrients in the blood begin to decline. This drop stimulates the feeding center in the hypothalamus which signals us to eat. When the nutrient level of the blood begin to rise, the satiety center is activated and our desire to continue to eat declines. Q: Name the four types of external forces that influence our eating habits and patterns and give an example of how you experience each in your life.
A: Sensory, Cognitive, environmental and health status. Examples will vary from student to student. Q: f a fudge brownie has 9 grams of carbohydrates, 1 gram of protein and 12 grams of fat. How many calories are in the brownie? A: Carb: 9x4 =236 Pro:1x4=4 Fat: 12 x 9 =108 36 +4 + 108 = 148 calories Q: There are six classes of nutrients. Name three that regulate body processes. A: Proteins, fat, vitamins, minerals and water Q: If a fudge brownie has 12 grams of carbohydrates, 2 grams of protein and 10 grams of fat. How many calories are in the brownie? A: Carb: 12 x4 =48 Pro:2x4=8 Fat: 10 x 9 =90 48 + 8 + 90 = 146 calories Q: There are six classes of nutrients. Name three that provide structure. A: Protein, fat, mineral and water Q: There are six classes of nutrients. Name three that are considered macronutrients. A: Carbohydrates, Protein, Lipids/Fats and Water Q: An individual’s health can be assessed using the ABCDE's of nutritional assessment. Below, indicate what each letter represents.

Name the three that supply energy. A: Carbohydrates, proteins and fat Q: Name the key hormone that causes a feeling of hunger. Indicate where in the body it is produced and the process by which it operates. A: Ghrelin is produced by the stomach and travels to the brain to stimulate the hunger center as it deactivates the satiety center. Q: The current recommendation to maintain your body weight is 2000 calories daily. If you are told that you should not consume any more than 23 % of your calories from fat, how many grams of fat should you eat in a day?
