Yes! I have also come to think that ketosis would be our natural state, and a state we would only leave occasionally (seasonal sweet fruits, etc). Eating a lot of sugar, which is something so many modern day people do because sugar seems to be in virtually all processed foods, creates a situation in which the body is over-producing insulin almost continually. I'm not diabetic or even near it, but if I eat a lot of sugar I feel quite sick, surely that is my body telling me to cut back immediately. I always feel best, healthiest, most energetic, most clear headed when I'm not eating any sugar at all.
