The high protein level is a realitive term. On a RDA diet the atkins protein level would be too high. On the Protein power plan the Atkins level would be too low. The ketogenic diet which is what Dr Atkins plan is uses fats as the primary fuel source and the amount of protein is limited to 30% of your daily cals which will be a different number of grams of protein for each person as we each have a different Basal metabolic rate and active metabolic rate. The Atkins ratio is 65% fats 30% protein and 5% carbs for weight loss. the fats go down some and the carbs come up some when you transition to premaintenance and maintenance. You will not find the ratios in the books just the words of warning about getting your protein intake too high or not trying to do a low fat Atkins.
Since insulin is also a fat storing hormone Atkins dieters don't want protein converted to glucose in the liver and stimulating insulin production since that would mean some of the dietary fats would be being stored during this glucose burning period. Protein power folks have a low dietary fat intake and aren't worried about ketosis or storing dietary fats. You can't compare the two plans levels of anything. Pick the program that works for you and then work it as the book tells you to. For Atkins folks that is high fat moderate protein and low carbs eaten daily from the accaptable food lists in the amount needed to satisfy your hunger at the time you are eating not just because it is allowable and you have room in your belly, drinking all the water, doing the daily required exercise and taking the supplements your body needs to make up for the ones lacking in your food choices. if you do all that then you too will be a big Atkins low carb loser.
Happy low carbing to you.
