Any thoughts on this study? It (apparently) shows no significant difference in weight loss when calorie reduction (below expenditure) is the same. The authors also found an increase in arterial stiffness in the high fat/low carb group. I'd love to see the details of the study.
More from Steven Novella at NeuroLogica Blog (I have a lot of respect for Steven, but he never met an anti-low-carb study he didn't like):
