Low carb works for weight loss and fitness

"Results: Sixty participants (82%) in the low-fat group and 59 (79%) in the low-carbohydrate group completed the intervention. At 12 months, participants on the low-carbohydrate diet had greater decreases in weight (mean difference in change, −3.5 kg [95% CI, −5.6 to −1.4 kg]; P = 0.002), fat mass (mean difference in change, −1.5% [CI, −2.6% to −0.4%]; P = 0.011), ratio of total–high-density lipoprotein (HDL) cholesterol (mean difference in change, −0.44 [CI, −0.71 to −0.16]; P = 0.002), and triglyceride level (mean difference in change, −0.16 mmol/L [−14.1 mg/dL] [CI, −0.31 to −0.01 mmol/L {−27.4 to −0.8 mg/dL}]; P = 0.038) and greater increases in HDL cholesterol level (mean difference in change, 0.18 mmol/L [7.0 mg/dL] [CI, 0.08 to 0.28 mmol/L {3.0 to 11.0 mg/dL}]; P < 0.001) than those on the low-fat diet."

"This article states that both the low fat and low-carb groups had similar daily caloric intake. The mean numbers reported are 1,448 calories for low-carb and 1527 for low-fat. The difference, 79 calories/day, if multiplied by the 356 days of this one- year study, would be 28,124 total calories. Since 3,500 calories = 1 pound, the difference in calories alone would account for an additional weight loss of 8.04 lb for individuals on the low-carb diet. Since that group lost an average of 7.7 lb more during the study, the entire difference can be the result of lower caloric intake. That additional weight loss might also play a role in the greater decline in other risk markers. Am I missing something?."
