Rafe over at rc3.org provides a very important bit of fact checking to the fast food infographic that is circulating. I thought 3800 seemed really high, but I didn’t bother with digging deeper. He did. I’m coopting his post in it’s entirety (it’s short) for those who aren’t reading his blog.
I’ve seen a number of links to the Everything You Need to Know About Fast Food infographic, which is chock full of interesting statistics, not all of which I’m entirely sure are accurate. It lists the average caloric intake for Americans as 3,760 calories, but I am pretty sure that is impossible.
This statistic comes from the UN Food and Agriculture Organization, but unfortunately the link is dead. Other sources report that the average caloric consumption for men in the US is around 2,618 calories for men and 1,877 calories for women — significantly less. A little back of the envelope math shows that the number cited in the infographic is impossible. The average height of men in the US is 5′ 9.5″ and the average weight is 191 pounds. The resting metabolic rate for 25 year old men of average height and weight is about 1900 calories. If you eat only 100 more calories a day than you expend, you’ll gain 10 pounds per year.
I’ve seen this number being repeated a lot, and I wanted to point out that there’s absolutely no way it’s correct. I haven’t seen the original source data, so maybe it’s a valid statistic that’s being misused, but in the context people are using it, it’s wrong.
