Answer to Question 1

Presence of a malignancy may cause systemic effects such as:
- Increased metabolism
- Altered metabolism
- Anorexia
- Dysgeusia
Alterations in metabolism may include:
- Insulin resistance
- Increased glucose synthesis
- Gluconeogenesis
- Increased Cori cycle activity
- Increased protein catabolism
- Decreased protein synthesis
- Increased lipid metabolism
- Decreased lipogenesis
- Decreased activity of lipoprotein lipase.
Fatigue and emotional trauma may also impact nutritional status.
Cancer treatment additionally add to these complications and may further reduce nutritional intake.

Answer to Question 2

6 pack beer: 150 kcal/beer x 6 = 900 kcal
4-5 shots bourbon: 100 kcal/shot x 5 = 500 kcal
Total: 1400 kcal/d on weekdays or about 70 of daily calories from alcoholic beverages alone.

Alcohol caloric contribution:
Beer (assuming 4.2) = 6 beers x 360 mL/beer x 0.042 g/L x 7 kcal/g = 635 kcal
Shots (assuming 80 proof) = 5 shots x 45 mL/shot x 0.4 g/L x 7 kcal/g = 630 kcal
Total: 1265 kcal from alcohol (ethanol)
