"However, from an optimization and sports performance perspective, I think that a complete complement of amino acids should be eaten each meal. There are some data to support that there's an `amino-stat' in the brain that senses blood amino acids. And if we eat incomplete proteins, the body releases the `missing' amino acids from muscle to balance out the blood amino acids ... It's hard to build muscle or recover from training adequately if your diet is kicking off a muscle catabolic sequence." IS IT POSSIBLE TO BE VEGAN LONG-TERM USING ONLY WHOLE FOODS AND WITHOUT PROTEIN SUPPLEMENTATION? IS IT POSSIBLE TO BE VEGAN LONG-TERM USING ONLY WHOLE FOODS AND WITHOUT PROTEIN SUPPLEMENTATION? "Yes, without protein supplementation, it's totally possible, but it's much more di cult. And without some guidance, it's unlikely that people will do it properly if muscle building or high- level sport performance is the goal. "But it is possible."
