Here's a version of the same story that weighs in a little heavieron how the obese cause global warming.

Next they're going to claim breathing, belching, and farting creates greenhouse gas.  Not indigenous peoples though, just fat white imperialists of European ancestry.

I'd like to see a study of how much more petrol, on average, an obese person uses, compared to a man of my size, 165lbs at 72inches.  If anyone has a link...?

Simple math.

Here is a quick example (with light explanations) of the variables - using my situation as an example; you build the formula however you like.

The car I drive has a tare weight of 2950lbs (700lbs of which is unsprung) displaces 2.4 liters and has a drag co-efficient of .31 with an average speed (including idle time, traffic lights, grid lock and highway driving) of 34mph.  My fuel consumption, on the average is 27mpg, with a weekly average travel distance of 420 miles. My weight is 220lbs (74") which is the standard load 4.5 days a week, 2.5 days a week the load averages 600lbs (teenagers).

(Now a larger vehicle, while having poorer initial mpg will be less affected by the passenger weight fluctuations but more affected by weather fluctuations due to poorer drag co-efficient.  If that vehicle is rolling on dubs (22's Yo!) the increase in unsprung weight will have a dramatic negative effect on the efficiency of acceleration.)

When building your formula be mindful of weather fluctations and the fact that I like to take a dump after lunch so my average weight is probably 3.4lbs less during the second (but slower half) of my daily commute.

So now you just use the formula and insert passenger weight variations and you'll have your answer.

**Late Edit: I forgot to note that petrol weighs around 6.2lbs per gallon so keeping your 20 gallon tank full instead of at 1/4 has the same effect as adding 90lbs to your frame (making you morbidly obese)**


But I'll save you the grief - the impact is inconsequential at best.
