@Hgreen56 I agree, but I think the best way to improve insulin sensitivity is to lower FAO. So this would naturally rule out low carb diets as a effective tool for controlling insulin resistance. People who eat low carb ketogenic diets are losing weight because of increased FAO, not because they're improving insulin resistance. In fact, their insulin insensitivity actually gets worse. Burning fat for fuel shuts down the oxidative metabolism, you're losing weight because of high stress hormones. There's been a few studies (a couple on this forum I believe) showing low carb diets increase the chance of diabetes, heart disease, and cancer despite subjects losing weight on the diet. This is due to the deterioration caused by cortisol.
