How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake? Options: A. Dose; Increase dose     B. Dose; Decrease dose     C. Dose; Do not change dose     D. Interval; Increase the interval between doses (give the drug less frequently)    E.
