Why they are, not sure, God made em that way I guess . (that's what I tell my kids when I don't know the answer.) But i do know that they are VERY high in nutritional value, so a little gives you a lot of good nutrition, and the good cholesterol too.
I also found out the hard way.
I munched em a lot for about a half a week and it stopped (and slightly reversed) my weight loss because of the high calorie content.
Nuts are high in calories due to their high fat content.
And if my logic is correct, they need to have a high fat content to give the little seed enough energy to become a tree.
I need nuts and PB to get to my daily cals, they are awesome.
I just ate an oz. of nuts as my 3 pm snack. I measure them out and then stick to it. With a cup of tea with one sugar packet it makes a nice snack that tides me over til dinner. A container of nuts can last me weeks and all the fat content satisfies me so I don't binge. Check out different types of nuts -- some are lower in calories then other. I love Brazil nuts but they are the worst, so I buy other types.
Also, try half a serving of lightly salty nuts with half a serving of raisens. It is a nice sweet and salty combo and high in fiber and protein.
I love almonds and pecans! I eat them as snacks mized with dried friut, mostly cranberries...It is very satisfying because its like crunchy and chewy all at the same time...but only like half a serving
None of these answers truly answer the reason why... If you've taken biology you may know that plants store glucose from the polysaccharide, starch. This helps the plant store energy so that it can grow during germination (the growing of a plant in an active state). In order to produce energy the chlorophyll or plant cells captures the sun's light to convert to energy, but because nuts do not have leaves and are not green, they focus on using fermentation to build up their energy supply so that they can continue to grow. Excess energy results in excess glucose which is why nuts are so high in calories. You are consuming all of the excess energy that the nuts have stored inside of them.

I just want to say I share your feelings.
Sometimes when I am drinking a beer (or more), I get the urge to munch on nuts such as mixed-nuts with no peanuts, etc. I can easily watch a football gave on TV, drink my beer, and consume an entire can of nuts that contains over 2000 calories.
LIFE AIN'T FAIR!
Lol because of the fat in them! You'd see how much oil you can get out of them if you grind up peanuts in a food processor to make your own peanut butter. Or all the oil you find at the top of the peanut butter jar that you have to stir up and refrigerate.
