ELI5: How are nuts so high in calories, yet so healthy and good for weight loss?

I'm on a diet and bought a 2 3/4 oz bag of mixed nuts and it's 470 calories (380 from fat). This kinda goes against everything I've learned about calories and weight loss.

They're healthy but not "eat all you can" healthy. They are nutrient rich, and the fat in them will help curb your appetite making it easier to make it to your next meal time without snacking. The energy you get from eating them will last a good long while with no crash. That being said you must still limit the amount you eat, and supplement your diet with other food groups.
