Wellness Core has 360 calories per cup: http://brands.wellnesspetfood.com/core/dogs/dry-formula-reduced-fat.

Annamaet Lean has 350 calories per cup: http://annamaet.com/products/Lean_Formula.

They both are well respected foods. I believe that many of the 4 star grain free foods may not be labeled as “diet” foods, but are even lower in calories. Best of luck to you.
