I tend to adhere to the "caveman" diet and not worry about fat or calories, and instead try to avoid eating too many sweets and carbs. It may not work for everyone, but it has been effective for me. Having celiac disease eliminates a lot of carbs by default, but peanuts are an easy snack that aren't terrible for me. However, obviously all things are best in moderation, and I'm like you - if I'm not careful I could down half a container in one sitting.
