Obesity and Gasoline Consumption

Are you driving the F350 because you're fat? What's the connection?
The Facts
1. Weight gain since 1960s 0.8 percent of gasoline consumption by passenger vehicles in 2005
2. F350 15-19 mpg
3. Bigger people want a bigger car
4. More weight, more gas

Both obesity and gas consumption are two significant issues in the United States today. Now, our question is, are they linked? It has been stated that since the 1960's weight gain amounts to 0.8 percent of gas consumption in 2005.
As an example we can look at the F350, the vehicles mpg is stated to be anywhere from 15-19 mpg. Typically bigger people want a bigger car. No one wants to be crammed in a small smart car if they weigh 300 pounds. Though, with a bigger car comes a price to pay, literally. Larger cars typically use more gas faster, but if you weigh more that can add to how fast you lose gas. Stated in Huffington Post for every 100 pounds in your car that gets approximation 31 miles to the gallon you will have about 30 added dollars to an annual gas bill. So, a car with lower gas millage and a heavier person would result in much more added money to an annual bill.
It has come to our attention that heavier people are more likely to drive a larger vehicle; and these larger vehicles will result in higher gas consumption. Though, even if a heavier person were to drive a smaller car that had lower gas mileage they would still receive a higher bill due to their weight.
