> For intense [[exercise]], it's about a gram per pound of body weight. > I've always been very sedentary, but I have usually had close to 150 grams daily. The traditional meat eaters didn't waste anything,ate all the [[skin]], ears, tails, snouts, feet,tendons, [[lungs]], intestines, marrow, blood,brains, gonads and other glands, picked the ligaments off the bones, so they had a much better balance of amino acids. (Small town restaurants in Mexico, China, etc., still serve those.) Muscle meats are essentially a refined food. > That's more than enough, and with low [[thyroid]] function the excess of tryptophan, methionine, and cystein can lower your [[thyroid]] even more. Until your metabolic rate is higher, 80 to 100 grams would be better. Replacing it with [[sugar]], or very well cooked [[starch]], would support [[thyroid]] function. > It's better to take your protein during the day, [[sugar]] and fat in the evening. The powdered protein lacks most of the nutrients, so you probably need some [[fruit]], [[eggs]], and liver, for the other nutrients, including potassium and [[magnesium]]. > Food proteins stimulate insulin secretion, and to prevent hypoglycemia cortisol is increased. The food proteins (along with tissue proteins) can be used for energy under the influence of cortisol. Meats, other than beef, lamb, venison, and bison, usually contain enough polyunsaturated fat to affect estrogen, [[testosterone]], and energy production. Stress, or increased cortisol, increases the circulating cysteine and tryptophan from muscle (meats), and these together with cortisol tend to increase aromatase. The high ratio of phosphate to [[calcium]] in meat activates a variety of stress processes; a high intake of [[calcium]] supports energy metabolism. Sugars tend to lower circulating free fatty acids, amino acids, and cortisol, while activating the [[thyroid]] hormone. > I think it just takes a few hours, or a day, to normalize the tryptophan. Vitamin B6 helps to guide the metabolism of tryptophan away from excessive [[serotonin]]. > [Does a protein deficiency lower liver detoxification due to increased muscle breakdown which inhibits [[thyroid]] via amino acids which lowers metabolic efficiency of liver?] Yes, I think that's at least part of how it works. > [Why do you recommend to have carbohydrates with a protein meal?] It mitigates the damage produced by the stress response to hypoglycemia.
