Carbohydrates are the most accessible source of energy for your body, but they aren't the only one. For those interested in the mechanics of how fat can be used as an energy source instead of carbohydrates I recommend looking up Ketosis. It is a huge misconception that "the more fat you eat the more fat you get." Simply having excess energy intake (from any source) will gain you weight -- although the energy requirements for body maintenance is different for everybody. Having a deficit will lose you weight. Of course it is a little more complex than this, but generalising like this makes it simpler to understand and follow. Personally I keep a moderately low carb diet (I eat most of my carbs before strenuous exercise) and eat high protein/fat. - http://en.wikipedia.org/wiki/Ketosis http://en.wikipedia.org/wiki/Ketosis - Alternate infographic about drinking carbonated drinks: http://imgur.com/w6C0s http://imgur.com/w6C0s
