Nice article! The upshot is that the boom of Chinese commodity prices in the mid-2010s is what stopped poor countries from catching up. That's a high level answer, but there's more nuance to it. In many places, I firmly believe the poor governance added with unnecessary bureaucracy is how half the countries lose sight on development. The prime example is India and to some extent Brazil.
I liked the new guidelines given here [1]. However, I disagree with the protein target recommendation. Feels way too much for a normal healthy adult with reasonable activity.
> Protein target: 1.2–1.6 grams per kilogram of body weight per day.
Trying not to be too negative but this is quite a long blog post for what effectively just comes down to using a piece of paper to measure something, which I imagine lots of us have done in a pinch. Also, nit: one of the calculations on paper size seems duplicated due to a typo.
If you have a Pro or Pro Max model of iPhone from the last several years, it has a LiDAR that allows the pre-installed Measure app to measure lengths/heights, etc., using the camera. Several higher end Android phones may also have the same.
