Hi Rick-
No, supposed quality of a food has nothing to do with how much you feed. It is revolved entirely around the amount of kcals per cup.
Just as an example. Orijen is considered still by a lot of people to be one of the best dry dog foods. The Orijen “Original” is 449 kcals/cup. My dog for his weight would eat 2cups a day according to their website. Now when I look up Purina Dog Chow, considered one of the WORST dog foods by many, it is 419 kcals/cup. According to their feeding guidelines for my dog, he would eat roughly 2 cups a day as well.
