Save Gas Money by Loosing Weight

It has been recently discovered that skinnier people save money on gas, how is this possible? A study has proven that "Americans are burning one billion more gallons of gasoline each year than the aid in 1960 because of their expanding waist lines. Simply put, more weight in the car means lower gas mileage." Basically, by less weight in the car, the less gas consumption by your car.
Since obeseity is a rising problem in America, Gas prices are also increasing; which means more people go through gas more qucikly and have to spend money on gas more often. Luckily, for the thinner and in shape Americans gas prices are not really a problem because they fuel up less then over weight people. This is an amazing and a crazy theory, but it has been proven true that people who are not overweight do not spend as much money on gas. Now, researchers are not saying you must loose weight to save money, but it is a good idea for famalies and people on budgets or who may travel a lot. Our basic solution by a scientist is "Eating less, driving less and choosing more active means of transportation would reduce gas consumption, and also reverse rising obesity rates"; how amazing this would be!
