The only way to eat 3000-5000 calories per day is to be @ ~50-60% calories from fat.
Otherwise, the caloric density of any other food makes a figure like that very uncomfortable to put down.
I remember reading a study a while back, where it really IS THE CASE, that the Fluffiest-Americans are not eating a significantly larger volume of food, but they are downing way more FATS, which have the highest caloric density @ 9 calories per gram, and NO fiber..
Try eating more than 2000 calories of rice and cabbage, it's HARD-Mode.
Not proud of this, but RECENTLY due to the Costco Oreos sale, Tp4 has eaten over 2000 calories of oreos in 1 day, And was still hungry at the end of it.

I know what you say to be accurate, but remember this is a census level measurement. Most people have poor diets and probably are eating a majority of their calories from fat. Anyone who eats at a restaurant (fast food or otherwise) generally gets ~1500 kcal from that one meal. Big mac + large fries + large coke (no refills) = 1330 kcal.
This is why I question "enough food" (see below).
I'm not sure which side to go with in this instance.
That shouldn't be hard to figure out.

Probably better to err on the side of empathy, but that article still relies on survey responses to the question of "have enough food?". I suppose it is useful for analyzing trends over time assuming people generally answer the same over time and the questions are the same over time, but each person's definition of "enough food" is probably different (and probably changes over time). Does that mean someone can eat at any time throughout the day for any reason (hunger, boredom, stress)? Does it mean the person eats three meals per day, and does that consider the size of the meal (how is size measured? Calories? Subjective satiety? Are vitamins measured?)? Does it simply mean someone is not literally starving (organ damage, stunted growth)?
I guess the survey results are probably sufficient for policy making decisions (i.e. keeping people happy and productive and not revolting). It's not scientific research after all. Also it's not an average: lots of fat people don't preclude lots of malnourished people.
To be clear, I'm not really arguing for or against anything. I'm just thinking through it.
