MATERIALS AND METHODS
1. Dependent Variable
Plasma levels of glucose, ketones, insulin, and glucagon
2. Independent Variable
Food and beverage intake
3. Controlled Variable physical activity, caffeine and alcohol intake, gender, age BMI
4. Why were physical activity and caffeine and alcohol intake the controlled variables?
Because you can control on the amount of time you spend doing physical activities and the intake of both caffeine and alcohol.
5. What type of assay was used to measure plasma glucose and ketone levels? glucose, oxidase, peroxide, dianisidine
6. What type of assay was used to measure plasma insulin and glucagon levels? glucose, oxidase, peroxide, dianisidine

1. When was plasma glucose concentration highest? If values are similar for several time points (within a few points of each other), then give range of times when plasma glucose concentration was highest.
Immediately post meal and one hour post meal
2. When was plasma glucose concentration lowest? If values are similar for several time points, then give range of times when plasma glucose concentration was lowest.
