I have mine at 15/45/40 (C/P/F). I am big on protein and am controlling carbs to lose weight.

Bump! Want to get this up so we'll get some more responses! :flowerforyou:

I ran across this website: http://www.archevore.com/get-started/
Here's a quote: "Archevore eaters typically range from 5-35% carbohydrate, from 10-30% protein and from 50 to 80% fat (mostly from animals) but wider ranges are entirely possible if you are not dieting and you are meticulous about the quality of your animal food sources. If you are trying to lose weight, really minimizing fructose and eating 50-70g a day of carbohydrate as starch is recommended. Skipping breakfast or at least no carbs for breakfast can be very helpful. If you are at your desired weight and healthy, 20% of calories as carbs is plenty for most very active people."

Also, I just finished reading 'The Paleo Answer' by Loren Cordain, and it said, "protein is toxic above 35 percent of a person's daily calories."

I think I'm going to start out at 30 carbs / 30 protein / 40 fat. That puts my carbs at 90 grams per day, which I'm good with, for now.

Also, I just finished reading 'The Paleo Answer' by Loren Cordain, and it said, "protein is toxic above 35 percent of a person's daily calories."

That is really interesting, does he go into detail about that? Right now I am averaging about 40% protein and would be really interested in why I should not.

Here's his most detailed excerpt about it from the book (that I could find). I'm not saying he's right or wrong (I'm trying to find the right mix myself). Hope this helps! :flowerforyou:

"I need to point out that there is a physiological limit to the amount of protein you can ingest before it becomes toxic. A by-product of dietary protein metabolism is nitrogen, which in turn is converted into urea by your liver and then excreted by the kidneys into your urine. The upper limit of protein ingestion is determined by your liver's ability to synthesize urea. When nitrogen intake from dietary protein exceeds the ability of the liver to synthesize urea, excessive nitrogen (as ammonia) and amino acids spill into the bloodstream, causing toxicity. For most people, the dietary protein ceiling occurs when protein exceeds 35 to 40 percent of their normal daily caloric intake. Consequently, very-high-protein diets for the average U.S. man could range from 187 to 270 grams per day and for women, 134 to 246 grams per day. Most modern-day Paleo Dieters eat high-protein diets that contain betweeen 20 and 30 percent protein."

I've heard that too much protein destroys the kidneys. I keep mine between 25 and 30%.

Thanks you just gave me a crash course on new knowledge I did not have before.
