I reviewed two latest meta-analyses on low carb diet (LCD) in order to conclude the magnitude of the metabolic outcomes (Hession et al & Kodoma et al.). I synthethized this data with the data from available long term trials (Shai et al 2008, Sacks et al. 2009 and Foster et al 2010). There is no striking deleterious effect of LCD on LDL -level, at most it's modest and compensated by positive changes in HDL, TG and glucose/insulin
