Question 7

Brian learns in his favorite nutrition class that he gets a larger percentage of energy from fat when he is sleeping than when he runs intensely for 3 miles. He decides that the best way for him to reduce his body fat is by sleeping all day. What is going to happen to Brian?

Accepted Answer

A)  Brian will lose the most fat if he sleeps all day. 
B)  Brian will only lose weight if he exercises at exercise intensities low enough to get him in his "fat burning zone." 
C)  Brian will burn mostly phosphocreatine and lactic acid as he sleeps, so this makes no sense. 
D)  Brian will not lose weight sleeping, it matters how many total calories of fat he will expend, not
What percent of his expended calories come from fat.
