The ratio of the carbon dioxide produced to the oxygen metabolised is called the respiratory quotient. It's around 0.7 for fats, 1 for carbohydrates and as high as 4 for oxalic acid.
For glucose
C6(H2O)6 + 6O2 -> 6CO2 + 6 H2O
The ratio is 1:1 between O2 and CO2.
However, for a fat
C16 H32 O2 + 23 O2 -> 16 CO2 + 16 H2O
the ratio is 16/23, which is around 0.7.

It all depends on what you had for lunch.
