Numb hands and feet are indications of blood capillary & nerve damage caused by high levels of insulin in your blood for sustained periods of time. Google "peripheral neuropathy." You might be prediabetic. You can diagnose it yourself with an inexpensive over-the-counter blood glucose meter using the finger prick test. The condition can be reversed by dietary changes but if you ignore it you'll cause lots of tissue damage and risk leg amputations, blindness, strokes, kidney and heart disease. Do you eat lots of carbs like breakfast cereals, bread, pasta, chips, and pizza? The human nutritional requirement for carbs is zero. Your ancestors rarely ate any carbs until the past few generations. So for example if your distant ancestors were Scandinavians they only had the opportunity to eat a few handfuls of wild berries near the end of summer. Think of the traditional natural diets of Sámi and Inuit people.
