Quote:

Eight young, slightly overweight men, ranging in age from 20 to 28, were placed in one of three groups. Group 1 consumed 104 grams of carbohydrate, Group 2 consumed 60 grams of carbohydrate and Group 3 consumed 30 grams of carbohydrate. After nine weeks, researchers checked for deviations in sodium, nitrogen and potassium levels, in addition to changes in weight and body composition. Body fat levels were evaluated using both skin-fold measurements and under-water weighing. At the conclusion of the study, researchers noted no statistical differences in nitrogen, sodium or potassium balances among the three groups. Differences in body weight and body composition were observed. Members of Group 1 lost an average of 25 pounds while those in Group 2 lost an average of 27 pounds. It should be noted, however, that Group 1 and Group 2 lost muscle mass as well (an average of 25% and 15% respectively). Eating a low-carbohydrate, higher-fat diet, Group 3 lost an average of 31 pounds over nine weeks. Of that lost weight, 95% was fat mass and only 5% lean muscle mass.

Here is an excerpt of the second study. This is only a summary, but outlines the results fairly well. Yes, I realize that the sample size was small and that all the levels were lower in carbs than the average American diet BUT...the group that was on the lowest carb level (30 grams per day) lost the least lean body mass (5% vs. 25% for the highest carb group and 15% for the moderate carb group). The lowest carb group also lost the most weight with the largest percentage of that weight loss coming from fat. Calorie levels were the same for all groups.

This seems to demonstrate what the original poster was asking for (less loss of lean body mass with lower carb levels). Whether or not you agree with the sample size and the carb levels is irrelevant...it shows what it shows.
