Abstract
Seven healthy male volunteers were fed diets varying in the amount of protein for a 12-week period. A low protein (32. 7 g/day) diet was fed for a 4-week adjustment period. This was followed by 4 weeks on a high protein diet (106. 3 g/day) and a repeat of the low protein diet (32. 3 g/day) for 4 weeks. The subjects were in negative nitrogen balance during both low protein periods and in positive balance while receiving the high protein diet. No differences in plasma cholesterol (free, ester, or total) or in plasma phospholipids were observed as a result of the protein levels fed. Plasma glycerides, however, were elevated during the high and final low protein periods.
