I've always heard that much protein... I've heard that much as well, but I've also read that .6 to .9x body weight in protein is good enough also. Though I'm really not sure how much I intake. Let's see. Cereal- 5g 16 oz. milk in the cereal- 16g hard boiled egg- 6g 1/4 lb deli meat in lunch sandwich- ~22g cheese on sandwich- 5g Fruit & nut bar- 8g protein shake w. milk- 30g supper meat- ~40g miscellaneous protein in other supper ingredients- 5g That gets me to about 137g. I weigh 190, so that's a multiple of 0.72. Not bad. Could probably get a bit more. Let me preface everything that I say here is that it's under the assumption that someone is a pretty active person who does a moderate amount of resistance training. By that I'm saying you lift-to-failure(or extremely cose) your muscles with concentric and eccentric resistance several times a week. Well, I say 1 gram per pound of "desired" body weight is the optimal starting point. so if you want to be 200 lbs, then 200 grams of protein per day. That would only be 800 kcal. Then thing is unless you're staving yourself from carbs to some degree the protein will be used for muscle building and maintenance. So.... the kcal don't really equate to energy or actual kcal the way you would normally count them. If you want to be 250 then 250 grams of protein or 1000 kcal. Again though, it's not like it will be burned for energy unless you put yourself into a a state where you're body needs it through some form of specific starvation. Best bet is to consume no more than 50 grams of protein in one sitting, and then wait ~2.5 hours to eat more. So if you're eating to be 250 then I would suggest 6 meals of 41.xxx grams spaced evenly over the day. Lost of guys I know need less, most guys I have helped are at 1 gram or more. I also don't know too many guys who could be 250 pounds lean. Just make sure you drink lots of water. You'd have to be fairly tall or fairly bulky for 250 lean; I'm 6'0" 243 (no, that is not bulk, unfortunately; BF%++) and I'm barely fitting into my 36 pants and XL t-shirts Right now I've just started mixing a pint of milk with two scoops of protein powder...stuff...following each lifting session, ~65g all told. I only lift 3 times a week so I probably won't see much in the way of results for a while...we'll see
