Yes that would be more than enough to eat in one day. You wouldn't eat the same thing every day obviously. You might live on that for a few days or a week at most then move on to something else. You don't have to have all your vitamins and minerals in one meal or one day or even a week. If you eat nutritious food and allow your body time in between to maintain itself correctly, not overburdening it with digestion 24/7 then the body will naturally conserve what nutrients aren't in the diet at any given time. Again looking back to nature we would go many months over winter without fresh fruits and no doubt there would be some vital nutrients we could miss out on for a season or more before they became available again.
The calorie value of a food is just one part of it. Whole raw foods are not numbers they are the fuel that our bodies have evolved to thrive on. Some days as you say it may be a pound of carrots providing our nourishment with little calorie value, whereas other days it may be a bunch of bananas and a couple of handfuls of nuts and other high calorie foods which would tip us way over the edge of that calorie chart. And yet again there are other days of course that we aren't hungry at all and the calorie count is zero. At no point is our body actually 'starving', not until a natural fast is taken to it's conclusion. The further we go from eating natural raw foods in the wrong combinations though, the more likely we will starve by eating too little food. i.e. dieting
