Yes, Dr. Naiman is pretty awesome!

He doesn't recommend calculating macros and calories. The idea is to get in your protein then use the fat and carbs as a lever.

1:1 is protein to fat plus carbs, and I understand this is more like a maintenance situation diet. I don't see carbs in the equation you have there. Generally, up to 100 carbs is acceptable, eaten as one meal in the evening, and going over this would involve active athletic types or at least committing to burning them off in exercise.

The floor on fat is something around 30 grams to keep from screwing up your hormones.

I don't calculate anything, and you don't need to. Focus your meals on protein and if you want to lose weight you need to work in more lean proteins. Steak and eggs are perfect maintenance foods. Working in lean chicken (I hate chicken breast, so I don't do this), lean seafood and shellfish is good. If you like yogurt and cottage cheese - super easy to eat a lot of this to get your protein up (0% unsweetened greek yogurt for example).
