How Are Calories in Food Really Measured?
The Howtown crew explains how food manufacturers, the USDA, and food label services figure out how many calories are in the foods we eat. Spoiler: it’s not just a matter of burning food to see how much energy is produced — different nutrients are absorbed more or less efficiently by the body so you need to measure the output and compare it to the input.

This is the name that'll be displayed next to comments you make on kottke.org; your email will not be displayed publicly. I'd encourage you to use your real name (or at least your first name and last initial) but you can also pick something that you go by when you participate in communities online. Choose something durable and reasonably unique (not "Me" or "anon"). Please don't change this often. No impersonation.
Note: I'm letting folks change their display names because the membership service that kottke.org uses collects full names and I thought some people might not want their names displayed publicly here. If it gets abused, I might disable this feature.
If you feel like this comment goes against the grain of the community guidelines or is otherwise inappropriate, please let me know and I will take a look at it.
