What is your opinion on this, quite damning review? http://www.stephanguyenet.com/bad-sugar-or-bad-journalism-an... as well as this one https://nutritionsciencefactcheck.com/2017/07/20/the-case-ag...

> Rather, I say this book doesn’t need to exist for the following reasons: All of the reasons that follow boil down to, essentially, "this book is so obviously true that there's no need to read it." That's hardly a damning review, it's a bit closer to the most vehement agreement possible.

Did you read the rest of the review? Here is an example quote:

"Scientifically, The Case Against Sugar suffers from a condition Steven Pinker has called the “Igon Value Problem”. This term describes the tendency of certain science journalists to arrive at obtuse conclusions due to a superficial understanding of their subject matter"

and later

"Taubes argues that sugar is the only factor that reliably shows up when a culture develops Western noncommunicable diseases, supporting the point with examples of cultures that adopted sugar-rich diets and became ill. Yet he makes no effort to look for a counterexample that could refute his argument: a traditionally-living culture that has a high intake of sugar and does not suffer from Western noncommunicable diseases."

These are just two examples. My understanding (from those two reviews only!), is that you will come away LESS well informed when reading this book. Now, if you provide me with an expert opinion in favour of the book, I'm happy to change my mind.

FYI Apart from moments where I try to recover fast (1-60min) from a near max physical effort, I avoid sugar anyway. I do NOT promote eating sugar.

Sure. And please note, I'm not prescribing or suggesting anything about the end of the world regarding a single missed night of sleep. I am commenting about the world of ignorance I had regarding sleep prior to a very recent education. If you or other people reading this are unaware of the depth of what sleep research has learned in the past 15 or so years I will point you to this six hour conversation that Dr. Matth…

I don't want to be dismissive, but is there a good TLDR on this, preferably in written form, or any other resources you'd recommend? I'd love to catch up on the science, but listening to six hours of podcast might cut into my sleep!

Here's my attempt after just finishing the book, after 4 hours sleep.

Sleep is much more important than anybody ever imagined and sufficient sleep is the cure to a large percentage of western societies problems. There are few financial incentives in promoting sleep so we do not hear about this over drugs, caffeine etc.

REM sleep is the source of creativity and thought resolution where different parts of the brain communicate that do not usually. Rem sleep occurs in the last two hours of an 8 hour sleep.

Non rem sleep is where the brain clears itself of the byproducts of brain activity. Without this the brain becomes damaged and is probably the cause of dementia.

Sleeping pills, LCDs, artificial light, caffeine, alarm clocks, early school starts and alcohol are all very bad.

Sleep in a dark room at 18 degrees celsius for 8 hours, allowing 1 hour to fall asleep.

re 'answering work emails until midnight: REALLY BAD' - true for any screen time. Night shift/f.lux or glasses with a blue light filter may help a little with that

I use Night Shift on all of my devices, and let me tell you, it doesn't help me get to bed any earlier.

It's to help reduce suppression of melatonin production, which can be up to 50%.

Kinda makes me wonder what the effects must be on those who work under endless 'crunch' type conditions, with 16 hour days/100 hour work weeks. That's pretty common in the video game development world, with articles saying conditions like that existed at the likes of Epic Games and Bioware.

Also makes me wonder if it has any connection to how buggy some of these games are, or whether that's just a symptom of the modern system allowing you to patch stuff post launch.

In most of the civilized world, including the PRC, that system is outright illegal.

Which means nothing unfortunately, as companies are still encouraging employees to stick to this work schedule

996 is encouraged IN PUBLIC

You're totally right. I was responding to the parent comment which felt temporary sleep deprivation was OK as long as it wasn't long-term. I'm arguing it is not OK even in the short term (not arguing that it is avoidable, just not justifiable as impactless)

Programmer in a start-up here. Please do talk about this with your workaholic colleagues as I did! We need to create an industry standard here. Sleep is super important to success and happiness, and I just recently found that sleep is not enough. I need also rest. If I don't have rest and relaxation often I get tired for several days regardless of sleep time. Writing this after deliberate 5 minutes downtime.

This may just be me, but when I was in charge of hiring a team, I ended up passing on sleep-foregoing candidates (often that wasn't the only thing, but it was a big factor for me). To this day, candidates that don't take care of getting enough sleep just to get things done, raise a red flag for me.

Curious... did you really ask candidates about their sleep patterns?

“Our results also show that sleep-deprived developers make more fixes to syntactic mistakes in the source code.” That statement, in isolation, could be taken completely out of context. Of course no sane person would conclude that a sleep deprived developer can fix more bugs. However there are many executive-level staff that are definitely not sane.

My guess here is that fixing those syntactic "mistakes" really means changing the code so it does the same thing, refactoring if you will.

I catch myself doing this sometimes when I'm tired or disengaged - spending my time on pointless refactoring or gold-plating. Presumably because these things are easier than what I should be tackling, but trick me into feeling productive.

I've bought recently one of those cheap wrist bands. One of the most important features for me was ability to measure sleep quality in terms of "daily hours of deep sleep," whatever that scientifically means. Over the course of several months, I've been able to identify things which affect my sleep quality: * eating late: bad * drinking late: one beer... not really that bad * answering work emails until midnight: REA…

I also believe sleep quality and carbondioxide level could be related. Need to get a device and give it a test.

Slight quibble: the fraction of REM sleep in each sleep cycle is highest during the last sleep cycle of the night.
