The basic fall back calorie amount for the average person is 3,000 calories per day. However, this can drastically change from person to person depending on their body’s metabolic speed and how active the are. A person who exercises daily will need more calories then someone with a mainly sedentary lifestyle.
I thought they based all the figures on Dietary Allowances on a 2000 calorie diet. That is probably more than enough than we “need to get by,” but the above information about the caloric requirement varying is all accurate. Maybe it was just a typo and bburg meant 2000 calories.
Since the question asks: How many calories do we “need to get by” I am going to go ahead and say it— for a fat person, the answer is Zero — if you have fat stored in your body, you can metabolize this stored energy and “get by” consuming these calories (a gram of fat contains 9 calories, whereas a gram of protein or carbohydrate contains only 4) — all you need to do is drink water (and you should probably take a multivitamin and eat a VLCD — which stands for very low calorie diet — if you are trying to loose weight) and the pounds (of fat) will burn themselves off (because instead of getting energy from food, your body will have to begin using the stored energy in fat cells). So the answer to this question, as it was phrased, is probably closer to 1000 calories than it is to 2000 (for your average American)!
The number is very dependent on a person to person basis. For atheletes or people who burn a lot of calories, you need a lot more calorie intake than a person who doesn’t work out as much. I read somewhere than Michael Phelps eats close to a 11,000 calories a day but he definitely burns it off in the pool. I think an average person probably “needs” around 1500-2000 calories a day.
