1
Q
Do lipids generate more or less co2 for every o2?
A
Less so you need to breathe less
2
Q
What is the respiratory quotient?
A
The ratio of co2 production to o2 consumption
3
Q
What does an RQ of above one tell us?
A
The person is respiring anaerobically
4
Q
Which types of foods have the lowest to highest RQ?
A
Fat, protein, sugars
5

6
