I think the 80/10/10 is an excellent guide and should used as such. Seeing that I consume avocado and some nuts regularly I probably hit closer to 15% on average regarding fat consumption. I doubt that my protein intake would exceed 10% of total calories most days even though I do eat some sort of legume regularly. I eat a wide variety of fruits, veg, fungi, whole grains, legumes and some nuts/seeds - or whole plants foods both cooked and raw. I think this is a better strategy than narrowing you choices which can be the case when only eating raw.
You are correct that each of us are unique as individuals but we are of the same species so in that respect our diet should the very similar. Just as all elephants eat green vegetation as their primary food source, all primates eat fruit and greens as their food source and on and on. You will not find animals of the same species varying their food source. Neither should we. Although there will be day to day variations in the percentages, 80-10-10 should be your goal for general intake of carbs, fat and protein. Those aren't arbitrary numbers. They are the number that have been established through research and experimentation by many.
If I eat high raw and enough calories, my protein is usually in the 10% range automatically and I do not have to worry much about it.
I feel better eating 10%+ from fat calories. I also look at it as an average. One day I might eat 15-20% and the next day binge on oranges.
These are guidelines to follow, but not to worry too much about getting it exactly right every meal or day.
i eat like 87/6/7
90/5/5 as i find any overt fats slow me down and they make me crave all sorts of things..
Are you also interested in people who eat about 90/5/5??? I ask this because this is WITHIN the 80/10/10 cal% ratio als Doug Graham describes it in his book. He says (on average over the year, and as an adult) you should eat AT LEAST 80cal% carbohydrates, and NOT MORE than 10cal% of both protein and fat. Many people on 80/10/10 do 90/05/05...
When I eat only raw fruit and vegetables (no overt fats like nuts and seeds, only rarely an avocado) and I track all I eat in cron-o-meter it calculates me a ratio of about 90/05/05. Eating an avocado every second day I get more in the 80/10/10 range.
