Question

HNDS 448 Advanced Nutrition .Worksheet 2 Lipids Case Study: Elroy was diagnosed with Lennox-Gastaut syndrome when he was 2 years old. Lennox-Gastaut syndrome is a severe form of generalized epilepsy that results in the frequent seizures. It is also associated with intellectual disabilities and developmental delays, likely due to the repeated neuronal insult from the seizures. After trying a number of different medications, the doctors have failed to find one that is able to control Elroy's seizures. Therefore, his doctor recommends that Elroy start on a ketogenic diet to severely limit the amount of carbohydrates in the diet. While this diet is thought to be fairly successful, it is important to calibrate carbohydrate intake precisely to avoid serious side effects. Therefore, Elroy and his parents are working closely with a dietician to ensure that he meets his minimum carbohydrate requirements for glucose-requiring tissues, while still limiting carbohydrates enough to prevent seizures, and simultaneously meeting the regular energy requirements for the rest of his body. 1) When Elroy first starts this diet, his glucose levels decrease. What process increases in order to provide energy for glucose-requiring tissues? (1 point) a) glycolysis b) ketogenesis c) fatty acid oxidation d) lipogenesis e) glycogenesis 2) In addition to brain cells, which other major cell type is unable to gain energy from fatty acids? (1 point) a) adipocytes b) red blood cells c) blastocytes d) enterocytes e) hepatocytes For every 2.2 pounds of body weight, Elroy should be eating approximately 75-100 kcalories, with 1-2 grams of those calories specifically from protein. Additionally, he should be eating fats and carbohydrates +proteins in a ratio of 3:1, with 3 grams of fats for every gram of carbohydrates and protein combined. Elroy weighs 22 pounds. How many grams of carbohydrates should he be eating in a given day? (Remember 1 gram of fat 9 kcalories, 1 gram of protein 4 kcalories, and 1 gram of carbohydrates 4 kcalories). (1 point) a) 97 g carbohydrates b) 1 g carbohydrates c) 64 g carbohydrates d) 248 g carbohydrates e) 15 g carbohydrates 3)

Answer 1

1. Fatty acid oxidation ( when a person starts ketogenic diet , his glucose level decreases. In order to provide energy for tissues oxidation of fats will occur)

2. Red blood cells ( many tissues can use fat or protein as an energy source, but the brain cells and red blood cells can only use glucose as their energy source.)

3. 64 g carbohydrates.( 64×4= 256 k calories. 22 lbs wt. He needs 750 to 1000 kcal)
