    The average adult man in America needs about 2000 to 3000 calories daily; people following calorie restriction may limit themselves to as few as 1200 calories.

I've long thought the suggested calorie guidelines are nonsense. Are you plowing a field, or tapping at a keyboard? We wouldn't think that leaving a car to idle in the driveway or driving 100 miles would use the same amount of fuel.

I would guess my daily intake is around 1200 calories, sometimes more, sometimes less. If I were eating 2000 calories per day, I would start putting on weight. If I kept it up for a year, I'd probably be overweight. Also, I am sure that 2000 calories of steak isn't the same as 2000 calories of rice, or 2000 calories of soda.

Rather than caloric guidelines, I think the focus should be on weight. If you are over your ideal weight, you are eating more than you need for your lifestyle.
