The basic argument of Taubes is that insulin makes the fat-cells (called adipocytes) store fat and inhibits the release of fat from the adipocyte. Since carbohydrates stimulate more insulin than both fat and protein, removing them from the diet means less insulin and with less insulin the adipocytes cannot store fat and actually makes the fat inside of them come out from storage to be used as energy. Taubes believes this is a beneficial response... but
When you look at the underlining cause of diabetes, you see insulin-resistance within the adipose-tissue [1]. This means that in insulin-resistant states like diabetes, the adipocytes are unable to store fat and all the fat in storage is being liberated out for fuel. Uncontrolled diabetes is associated with increased lipolysis and elevated free-fatty-acids [2]. So how is it that an Atkins type diet is suppose to reverse diabetes like Taubes' claims? The very first study ever done on the Atkins diet back in 1980 showed that it nearly doubled the amount of FFA's in the blood [3].
As well researched as Gary appears, I cannot understand how he does not realize this. Maybe one day he will read this and have an A-HA moment!
