Lyle McDonald is a keto guy. Tons of info on his ketogenic diet, which is just low carb dieting, similar to Atkins and South Beach and all the other low carb style diets out there. His whole philosophy is high protein and low carbs, great for weight loss but I'd have to read his book and see his philosophies and understand more about what his composition is for high activity/high intense level athletes. Hope to read his book soon.
Benefits of protein intake from 1.2-1.8g/kg have shown to have an anabolic effect and show a moderate increase in weight gain over time, without excessive intestinal irritability. Again, I'll have to read his book to make any conclusions, but in my studies, 3.3g/kg body weight as mentioned in one of the articles may be excessive.
