It's always crazy to me to be reminded that people were doing so well in the past that they could be this obese, and I wonder if it really was a paradise or if there were enough downsides to justify the way we do things now.

Any calorie tracker is basically a spreadsheet though. It's just packaged in a nicer UI, and you get to skip a lot of setup. Manually entering new foods is probably the least fussy part.

The only flaw I can find with this app is that I'd broaden the statistics feature functionality. Been very happy with it for years.
e: Not a fan of the database search either. I'd forgotten it exists because it's bad enough that I don't use it, lol. Barcode scanner works fine though.
It is demonstrably true that life on a planet alters the conditions of the planet (which then alters the life, etc). Most glaring is the abundance of oxygen in our atmosphere. We don't look for oxygen on other planets because oxygen is necessary for life; we look for oxygen because it's unlikely to exist in high densities without life to produce it.
The sci-fi novel Death's End by Cixin Liu (third in a series) further suggests that life alters the universe rather than just local systems, which was a fun idea. He's a rather long-winded author, but he's easy to forgive.
That said, this is the first time I'm hearing of the hypothesis by name, so I can't be sure what all it says. A quick skim lines up with reality though.
