The advantage of the Cat Food Diet is that it’s super fast, because it’s super low calorie and super structured. It’s almost impossible to screw up, if you follow my rules exactly. The disadvantage of the Cat Food Diet is that it takes you off the planet as far as social eating is concerned. Your food is very structured, and you have to follow it exactly. If you are in a restaurant, order shrimp cocktail or soft boiled eggs. The advantage of adding olive oil (2 tablespoons per can) and cutting down your cans of Cat Food from 2 to 1 per feeding, is that you’ll feel fuller and have fewer sweet and starch cravings. The disadvantage of adding olive oil is that it can slow down weight loss a bit, as your calories can be slightly higher.
