Food != Calories

The featured article examines calorie intake and not food intake. A pound of apples has a much lower calorie density than a pound of french fries. Changes in the TYPE of food consumed (i.e. increase calorie density) agree with the featured article's conclusions.

I don't see where anyone got this confused.

The title of this HN posting is "Increased food intake alone explains the increase in body weight in US"

That is not true. It is "Increased CALORIE intake alone explains the increase in body weight in US"

I don't know about you, but I appreciate posters who copy article titles verbatim instead of editorializing. As for the article itself, it very clearly stated that increased energy intake was the culprit. The word "food" by itself does not indicate a unit of measure. Do they mean calories? Pounds? Liters? Let me read the first paragraph to find out OH THERE IT IS. It's calories.
