Protein absorbtion rate - how much should i eat and how often?

Question

I weight train seriously 3-4 times per week and do 2 other fitness related activities. i am trying to both lose weight and build muscle. i gather i should be eating around th 1.5g of protein per kg i weigh. is this roughly correct? how much protein can be absorbed by the body? ie. is it a waste of money if i eat more than a certain amount of protein in any 1 hour period as some of it will just pass through me?

if anyone knows a figure that for example, "only 20g of protein can be absorbed in any 3 hour period", that would be most helpful to know.

thanks very much!

I am 27 years old and weight train SERIOUSLY. ie. 0.75g of protein per kg of body mass is no where near sufficient.

Answer 1

it really depends on how old you are.

16 -18 year olds should eat 64 - 70g a day
19 - 64 year olds should eat 55g a day

the recommended daily intake (RDI) of protein is baes on 0.75 g per kg of body mass.

just remember though, that your body will only absorb as much protein as it needs, and no more.

Answer 2

those numbers from the RDI are for the sedentary individual not for athletes.

the more exercise that a person gets the higher the rate of muscle protein turnover in the muscle cell. this also means that the utilization rate of protein will be increased. I recommend the minimum of 1-1.5 grams of protein per lb of lean body mass but in general the calories should be close to 40% protein, 40% carbohydrates and 20% fats

and that value of 20 g per hour is so inaccurate. there is no such maximum amount of protein that can be utilized. the amount will vary from person to person. the amount of LBM that a person has, the daily level of activity, type of activities, etc. all dictate how much protein "that" person needs and can utilize.

Answer 3

1gram to 1.5 grams of protein per body weight no more then 40-50 some say 40 some say 50 can be absorbed I always do 40. Take in 40 grams of protein every 2 hours. I also have been trying 40 grams of whey protein before bed seems to work well.
