Hear hear! 21 people? There's a definitive study.

No it isn't. Several studies that compare low-carb with low-fat diets report that the low-carb dieters lose more weight from fat than low-fat dieters. Here are a couple (but IIRC there are more):

• A Randomized Trial Comparing a Very Low Carbohydrate Diet and a Calorie-Restricted Low Fat Diet on Body Weight and Cardiovascular Risk Factors in Healthy Women
  "The very low carbohydrate diet group lost more weight (8.5 ± 1.0 vs. 3.9 ± 1.0 kg; P < 0.001) and more body fat (4.8 ± 0.67 vs. 2.0 ± 0.75 kg; P < 0.01) than the low fat diet group."
• Effect of a Hypocaloric Diet, Increased Protein Intake and Resistance Training on Lean Mass Gains and Fat Mass Loss in Overweight Police Officers
  The average fat loss was 5.5, 15.4 and 9.3 pounds in the three groups respectively. Lean muscle mass gains did not occur in the group that was on a low-calorie diet alone. But the casein group had an average lean muscle mass gain of 8.8 pounds and the whey group an average increase of 4.4 pounds. Average increase in strength for chest, shoulder and legs was 59% for the casein group and 29% for the whey group, resulting in a significant difference as compared with the diet-only group.

I wondered the same thing, since the article addresses only total weight loss, not what was lost. Kinda meaningless without that little data point.

This cought my attention, too: the calorie allotment was "1,800 for men"! Man, that sounds like some kind of starvation diet, unless these folks were real couch potatoes.

You should research what you are talking about. Low carb dieters experience much less muscle wasting than low calorie dieters.
