Maybe that doesn't tell you anything but 100 gr olive oil has more calories that 300gr of sugar.
Eating apples is natural for human beings,like many other fruits, eating peanut butter is not(apple has a lot of water with their sugar what makes it easy to process, and converting its sugars to fat would take energy).
They are other reasons for storing fat, e.g cold protection and cell and arteries protection from acids(produced by sugars burning).
>Eating apples is natural for human beings,like many other fruits
With a small correction that eating apples that were not bred for sweetness and did not contain as much fructose as today's apples is natural. Therefore, there is such thing as too many apples (and fructose is probably not better than glucose or sucrose in any way).
You compare nutrition of apples with peanuts, then say it's natural for humans to eat apples. It's natural for us to eat peanuts too - compare the nutrition of apples with peanut butter if you want to make that argument.
In fact, Apple(look at the nutritional values): http://en.wikipedia.org/wiki/Apple - Sugars 10.39 g - Fat 0.17 g
Peanut: http://en.wikipedia.org/wiki/Peanut - Sugars 0 g. - Fat Saturated 9 gr!! - Fat monounsaturated 24gr!! - Fat polyunsaturated 16gr!!

The calories approach is an oversimplification.
