Nuts have good fats and are somewhat okay in a VERY moderate amount.

But they have a crazy amount of calories. Nuts are not a thing to snack on, if you eat more than one handful, but it is easy to eat an entire bag and at that point just eat chips.

"A small 1.5-ounce serving often contains 240–300 calories, while larger bags (e.g., 100g) can range from 570 to 750 calories."
