Here is a must read for all on this list interested in the protein  
debate.  I believe it was Hillary McClure who first posted this link  
early last year.

To summarize with respect to daily protein requirements:

.8g/kg/day to 2.5g/kg/day

1) A person whose lean body weight is 41kg (90 pounds) will require a  
minimum of 33 and a maximum of about 103 grams of protein per day;

2) a person whose lean body weight is 64kg (140 pounds) will require  
a minimum of 51 and maximum of about 160 grams of protein per day; and

3) a person whose lean body weight is 91kg (200 pounds) will require  
a minimum of 73 and maximum of about 228 grams of protein per day.
