Hunter gatherer ancestors would have been in calorie restriction for many days, and then if lucky, into feasting and bingeing. We don't have to work so hard for our food and so Low Carb comes closest perhaps to our 'natural' way of eating as it does provide brakes to appetite. We have become used to daily 'feasts' and so overall, we get fatter. But low carbing, for me anyway, means that I am not looking for food all the time, and so eat less. But my eyes are still a bit bigger than my stomach even now...
