An animated explanation of the physiological differences between fasting and calorie restriction, focusing on insulin, ghrelin, and metabolism.

This is about the drastic physiological differences between fasting and eating less ▲Patreon: patreon.com/WILearned ▲Twitter: twitter.com/jeverettlearned ▲IG: instagram.com/jeverett.whativelearned/ *NOTE* One of the key things in being able to fast in a healthy matter is entering the state of ketosis - that is, switching your metabolism from burning carbohydrate to burning fat. *Considering most people have been burning carbohydrate their whole lives* this can make fasting a challenge. Upton Sinclair recommends doing quite long fasts - 12 days, but you may want to work your way up to longer fasts. Unless you are relatively keto adapted (or have experience with fasting of course), it's important that you take precautions while doing a fast. Fasting isn't inherently dangerous, *but diving into fasting when your body is in no way geared for it can be.* I recommend doing more research before doing longer fasts. "The Complete Guide to Fasting" (amzn.to/2tQjxXa) is a good book to start with. As Tim Ferriss puts it: Please don't do anything stupid and kill yourself. It would make us both quite unhappy. Just in case I should also say that of course you need to balance fasting with eating - You need to survive off of something. I have been doing intermittent fasting the past year (22 hours fasted, 2 hours eating - you can widen it to 16/8, which still provides great benefits) and will fast for a couple days every other month or so. Several other people have recommend a routine like this - Tim Ferriss recommends doing a 3 day fast once per month and a 7 day fast once per year. Also make sure you're getting enough fat, protein, micronutrients and fiber to maintain a healthy weight and healthy body - *excessive* fasting can be very dangerous. Books Mentioned: "The Obesity Code" by Dr. Jason Fung - amzn.to/2rXtalh "The Fasting Cure" by Upton Sinclair - (If you google the title you can find the full book online) "Tools of Titans" by Tim Ferriss - amzn.to/2rX6P7E [BLINKIST] Blinkist is an app I've been using lately to discover new books and review the ones I've already read. It gives you the key points in text or audio form from tons of different non-fiction books. Since I'm always going through so many books to get these done, it's very useful to get me exposed to more concepts beforehand to know if it's worth my time to buy and read through that particular book.

On “Can a Diet That Mimics Fasting Turn Back the Clock?”

I saw this video called "Fasting vs. Eating Less: What's the Difference? (Science of Fasting)" just yesterday, and it's good to hear many of the points it raised validated by your experience: link to this video > hunger comes in waves, you'll get to a point where you feel super hungry, it'll usually pass after some time Matches what the video above talks about "Ghrelin" from 5:03 onwards.

On “Things no one tells you before an Antarctic expedition (2015)”

The following sources provide some compelling arguments for switching to intermittent fasting for many major systemic health benefits. These videos by the channel "What I've Learned" are great: - Fasting vs. Eating Less: What's the Difference? 1 - Longevity & Why I now eat One Meal a Day 2 The channel 3 also has many other videos on the topic of nutrition, with similar emphasis. Also see the excellent and readable book "The Complete Guide to Fasting: Heal Your Body Through Intermittent, Alternate-Day, and Extended Fasting" by Dr Jason Fung and Jimmy Moore 4. 1 link to this video 2 link 3 link 4 link

On “Ask HN: What do you struggle with?”

Yeah my man, I seriously don't know what to tell other than fasting works. Your metabolism isn't a something that breaks and is not fixable, and "getting sick of fainting" isn't a fucking excuse. If you're fainting, you're doing something wrong with your diet. You either getting too little from something, or too little. I seriously hope this video can lead you to a better lifestyle. and sorry if I sounded too harsh, lowkey it's targeted to myself as motivation. link to this video

On “Ask HN: What Skills to Acquire in 2020?”

…ple preach intermittent fasting, which I've found is okay for maintenance and health but it's not nearly as beneficial nor will it lose you as much weight as fasting for days on end. But here's some material I went over to educate myself and convinced me that it's perfectly safe: Fasting vs. Eating Less: What's the Difference? (Science of Fasting) link to this video Dr. Jason Fung - 'Therapeutic Fasting - Solving the Two-Compartment Problem' link Beginners Guide to Prolonged Fasting | 24-72 Hour Fasting Instructions link ^^ Not exactly a fan of Thomas DeLauer but there's some good information there. If you aren't faint of heart, check out some videos on the "Snake Diet" channel on YouTube. Cole is…

On “What happens to your brain when you give up sugar”

…ad of searching for that chocolate treat, I’ll just sit for a but for 5-10 minutes, and let my body break down some of my fat to make more brain juice to operate normally. You are right though that people are different and this is a fricking complex stuff, and might not work for you, just wanted to mention that there might be more you can try. 1 link to this video…
