Barry Groves and Dr K are on the same wavelength:
"17. Why Low Carb Diets Must Be High Fat, Not High Protein"

"If we reduce the carbohydrate content of our diet, we either go hungry or replace the carbs lost with something else. There is currently a great deal of debate about what this should be. This chapter explains why carbs should be replaced with fats — and which fats they should be."
Why get hung up on exact ratios of carbs to fat to protein? Doesn't this cause the same problem as counting calories, which many feel is doomed to fail? So we can go as low carb as one can stand. Replace lean mean with fatty meat, or cook in coconut oil. Snack on macademia nuts. Eat bacon and eggs, with the eggs cooked in the bacon grease. Eat avocados. Eat Kielbasa.
Chinese love fatty duck and pork. The French eat a fatty diet (relative to the American Food Pyramid). Plains Indians commonly blended bear fat with their food:

Paleo does not automatically mean lean meat. Organ meats are fatty, it is likely paleos ate the entire animal as they did not have the American medical establishment around to tell them they could only eat lean meat or get heart disease.
The Lewis and Clark expedition ate 6-9 lbs of meat per person a day, and they greatly prized fat (pages 213-214

So perhaps lean meat by itself is bad. If one cannot reach Dr K's recommended level of fat grams, who cares? You can still use his basic idea, which is also a Barry Groves diet. Maybe follow Dr K ratios exactly if you are trying to cure diabetes, but if you just want to lose weight, a partial adaptation should be ok?
