Calories from Fat + Good fats

[bloc]

I've looked online and I can't find a simple explination for what this is. Or maybe I'm looking to hard.

When you look at nutrition facts they have # of calories, and # of calories from fat.
Take my protein shakes for example.
1 scoop:
110 calories
25 calories from fat
Now, from my understanding all things in food, such as carbs, fat, and protein add calories to the total # of calories. So, why do they go out of there way to just list the calories from fat? Why not break it down into calories from fat, protein, and carbs? Do you digest these fat calories the same way? Is there anything special about them?

Also, "good fats". I assume these are fats that are non-trans fat and non-saturated fats. How much fat should a dieter consume, for effective weight loss?
Again, for example my protein shakes.
2.5g of fat + 0.5 sat fat = 4% (based on 2,000 calories). For some one on a 1500 calorie diet whay % should they consume daily? %30? %15?
And if don't eat your daily % of fat in the food you eat, what are your thoughts on these fish oil pills? I hear these fats can help you loose weight.

Hope one of you can clear this up.

i suppose they list the calories from fat because ppl are misinformed about calories from fat. how often do we hear "oh that has too much fat" or "dont eat fat to if you want to lose weight." any wonder why over so many ppl are overweight?

ideally total fat should make up b/w 20 and 30% of total calories consumed. some go as low as 15%. this is one of the better articles on fat if you're interested
