A. True This gives a daily deficit of about 500 kcal which would be supplied by metabo-lizing fat stores.

B. True This provides a positive energy balance and allows replenishment of body pro-tein and fat, assuming an adequate protein content of the diet.

C. True Metabolizing at 10 METS for 6 hours (60 MET hours) would itself use up more than the daily sedentary requirement (e.g. sleeping for 8 hours, about 8 MET hours; average 2 METS for 16 hours, 32 MET hours).

D. True Ketoacidosis impairs muscle function.
