A soon-to-be published study in Appetite [2009 Feb;52(1):96-103] (but apparently already published online earlier this summer) done by a group at Tufts seems to have “proven” that when you remove carbohydrates for three weeks from the diet of people who have depended on them for decades, you get some short-term memory loss, fuzzy thinking and/or mood swings. In what appears to me to be yet another colossal waste of time and money, the Tufts researchers concluded that “the brain needs glucose for energy, and diets low in carbohydrates can be detrimental to learning, memory and thinking.” What? They got grant money for this? Most of my Primal Blueprint 30-day challengers could have told you that for free! If you understand the power of gene expression and the ability of the human body to acclimate, this study only “proves” what we’ve known for over 100 years.
