A Harvard Study just published in the Lancet shows that based on a Meta-analysis of 53 Studies shows the Low Carb Diet Superior to Low Fat Diets for Weight Loss.
I was most amazed that this study was funded by the NIH and the ADA. I will now add a few choice quotes from the study and a link and then go eat some nutritious meat. " In weight loss trials, low-carbohydrate interventions led to significantly greater weight loss than did low-fat interventions (18 comparisons; WMD 1·15 kg [95% CI 0·52 to 1·79]; I2=10%)." " Low-fat interventions did not lead to differences in weight change compared with other higher-fat weight loss interventions (19 comparisons; WMD 0·36 kg [−0·66 to 1·37; I2=82%), and led to a greater weight decrease only when compared with a usual diet (eight comparisons; −5·41 kg [−7·29 to −3·54]; I2=68%). Similarly, results of non-weight-loss trials and weight maintenance trials, for which no low-carbohydrate comparisons were made, showed that low-fat versus higher-fat interventions have a similar effect on weight loss, and that low-fat interventions led to greater weight loss only when compared with usual diet." Here's a LINK to the study.
