> your body closely regulates the level of glucose in your blood. Your brain would literally starve without it. Is this actually true? Having done the ketogenic diet and bringing carbohydrates down to almost nothing, my brain definitely didn't starve. In fact, running on ketones was amazing.
It was in the next line: Your brain would literally starve without it. If you do not consume enough carbohydrates in your diet, your body will synthesize the glucose you need.

Your brain needs glucose. When you are on keto, your body produces glucose for your brain.
I wonder if occasional long term fasts can reduce your cancer risk.
From my research, yes it can. I read a study that said patients who fast during chemotherapy treatments fare better too. The mechanism seems to be that during periods of fasting, normal cells "hunker down" and restrict the consumption of nutrients and other materials. Cancer cells don't do this though and continue to consume the nutrients, which are actually chemotherapy drugs in the patients. Fasting therfore increa…
more completely rid itself of cancerous cells by consuming them

The amount of carbohydrates you need in your diet to survive is exactly zero. They’re a non-essential macronutrient. The amount of glucose you need in your blood stream to keep everything running smoothly is a very small amount easily produced by your body through a process called gluconeogenesis. I went 60 days sans any calories and my body self regulated glucose just fine.
Eliminating carbohydrates from your diet means eliminating vegetables from your diet. I'm highly skeptical of the claim that any such diet can ever be healthy in the medium to long term. I fail to see how malnourishment isn't a certainty under such circumstances. The fact that humans can fast for weeks or months isn't evidence in favor of: > The amount of carbohydrates you need in your diet to survive is exactly zero…

You went 60 days without eating?

Uhh, I have a log of that somewhere one second... This is day 61, I'd estimate like 4k-ish calories. 07:51 - Woke to Alarm 08:34 - Weight 199.8 - Bodyfat 26.1 08:41 - Start First Meal - Handful of Spinach Wilted in 2 tbsp Butter - 5 Olives - 1 Dill Pickle Spear - 6 oz Pickle Juice 08:45 - End First Meal 08:50 - Drank 1/2 Liter Water 08:57 - Start Sauna 165.0 F 09:00 - Drank 1 Liter Water 09:12 - End Sauna 182.5 F 09:…
You fasted for 60 days and the first thing you ate to break your fast was... spinach? You have next-level willpower.

So then you don’t need to eat any carbohydrates at all? I’m really confused by the statement. You’ll never starve your brain by not eating carbs.

> Two normal men volunteered to live solely on meat for one year, which gave us an unusual opportunity of studying the effects of this diet. The term “meat,” as used by us, included both the lean and the fat portions of animals. The subjects derived most of their calories from fat and the diet was quite different from what one, who uses the term “meat” as including chiefly lean muscle, would expect.

> 11. In these trained subjects, the clinical observations and laboratory studies gave no evidence that any ill effects had occurred from the prolonged use of the exclusive meat diet.
People in the Arctic circle like the Inuit always lived almost entirely off of meat and Mongolians and other steppe pastoralists come very close, adding dairy.

What was the other thing?
Same thing that gets everyone on a fast, too much water, not enough electrolytes. Essentially got really really bad cramps in my legs each morning towards the end of the first 30 days. Fixed itself as soon as I added in the magnesium and potassium supplements. Likely caused because I drank too much water during the early parts of the fast.
