2kg in 2 days doesn't sound unreasonable at all. Glycogen and water loss from the calorie restriction will do that, along with maybe better bowel regularity from the fiber. Nobody is claiming they lost 2kg of body fat.

I don't think they do, people move around and swap seats. I expect they just find the losses small enough to write off. I was once travelling shortly after being issued a new debit card, but still had the old one in my wallet and used it by mistake and I wasn't charged. They never tracked me down for the cost of that packet of crisps!

I often enjoy movies that are unexpected and don't fit neatly into one established genre, but I think these tend to get lower audience ratings, while films that deliver to expectations do better, even if most of a randomly selected audience would dislike them. If a movie is a comedy, with a poster with big red letters and a white background, people know it's a certain kind of movie, and mostly those who enjoy those movies will go see it. Likewise with documentaries about some niche interest - those who watch it mostly sought it out because they're into that.

When cutting potatoes into chunks, for something like a stew, I often find myself thinking about this problem, and how I would write a program for a robot to do it.

They are fairly well approximated as ellipsoids of different sizes. Typically, I want pieces around half the volume of the smallest potatoes, but with the range of sizes, this means cutting the larger ones into at least 5 pieces. While it would be simple to make parallel slices giving equal volume, these would have very different shape to the halved smalls. Some can be quartered to give nice chunks, others into thirds with 2 perpendicular cuts...

That was one part of the article I found questionable- "If the body needs salt, those chips will cause a surge of pleasurable dopamine to flood the brain. If the body doesn’t need salt, that dopamine drip disappears"

Surely this second part is false? Most of us have got used to high levels of salt in modern diets, and prefer the taste of salty things even when we've had way more sodium than we need.

I definitely see effects on my glucose the day after when I change my exercise routine, such as doing an extra LISS session. Anticipation of something stressful or exciting does also have an effect. I haven't noticed any effect from simply expecting more exercise later (without emotions attached). I believe a lot of this comes down to liver and muscle glycogen storage and release. (I'm T1)

I remember reading about a physical device someone constructed with mirrors (I think at an early burning man) that gave you the experience of a huge inter ocular distance to get a giant's eye view. I've always wanted to try one (or the opposite to experience a tiny inter ocular distance).

I have noticed too that HN has an enduring fascination with quaternions, and they seem to reach front page surprisingly frequently (considering that there's not a huge amount of discussion of other geometry topics). I'm certainly not complaining though - I love quaternions too!

Hill walks are particularly challenging for me too. I can do rowing or weightlifting with my sugars staying fairly stable or rising if it's really intense, but something about walking steadily up a gentle slope makes it drop massively. There was some interesting research a couple of years back on how exercising the calf muscle is particularly effective at lowering BG, perhaps that has something to do with it https://pmc.ncbi.nlm.nih.gov/articles/PMC9404652/

Also when figuring out how much insulin is needed for a given amount of carbs you need to factor in the type of carbs, your individual response to that type of carbs, what fats/protein/fiber you eat with it (fats and fiber tend to slow down the BG rise from carbs, protein can cause a rise when eaten on its own but can also slow down the rise from carbs), what time of day it is (I need around double the amount of insulin for the same food first thing in the morning vs in the afternoon), your mood, what else is in your stomach already, the weather (hot weather can greatly increase insulin sensitivity), your current fitness level, what physical activity you have done over the last day or 2 and what you will do over the coming hours, where on your body you inject, if you are fighting any illness…
