There is no need for a blood test to figure out your insulin sensitivity, which is just another way of saying what the capacity of a human body is, when it comes to handling carbohydrates. If you get tired or they smooth out your physique, you are probably more insulin resistant than your average Joe. This means that your body creates a lot more insulin than someone else’s who can eat a lot of carbs and not get fat while doing it. Insulin resistance means that you shouldn’t eat any refined carbohydrates, sugar, juices, cold cereals, white rice or mashed potatoes. Slow-burning carbohydrates are your friend here – get some red potatoes, brown rice, pasta, buckwheat noodles and yams instead. They burn more slowly and will put that energy in your glycogen storage instead of your body fat stores by simply keeping insulin in your blood on a moderate level.
