What They Won't Tell You About the Keto Diet

Published 2021-01-14
Is a low carb diet healthy long term? This video discusses why keto doesn't work for everyone, addressing two common problems that are rarely mentioned: low T3 and high stress hormones.

    I was looking for some unpolarized views on keto, which was hard to find at first glance. Happy to have found one from somebody who had benefits from keto themselves. Thanks for a well made vid!

    Tip: Turn down the background music.

    This is like What I've Learned but somehow better, good stuff mate. I'm glad that keto got me into scientific research more than it did circlejerking in r/keto or some other forum. I never imposed a ketogenic diet on anyone but for a while I did believe it to at least be part of the 'optimal' diet. Nowadays I see that my worries have shifted more so to other aspects of nutrition like the consumption of rancid polyunsaturated fat and oxidised cholesterol. I dont even consider the carb content of anything I eat since that's really just a default for the things I buy and prepare. That thyroid thing has lead me down a wormhole of scientific understanding. There are both regulatory (like thyroid hormones) and counter regulatory mechanisms in the body (like receptors). It is near impossible to speculate the extent to which a NET change happens by looking a mechanistic explanations of physiology, and the absence of in vivo or vitro studies on these matters makes this so much worse. It seems that people just take stuff like 'Brain IGF1 receptor is increased in the ketogenic brain' and just run with it, when they didn't even stop to consider that IGF1 drops on keto, even with adequate protein and calorie intake.

    Found you on twitter months ago and just discovered your youtube channel. Thank you for your service.. you and the rest of the peaters have taught me a lot
  • @block36079
    It should be obvious to anyone who really thinks about it, I mean, the ketogenic diet stimulates the fasting state, do that for too long and cortisol understandably increases. This is a great video that definitely displays your understanding of the middle ground of nutrition without any bias, cheers!
  • @coreyfunch561
    Found this via Reddit. Felt informed and laughed at all the pop culture references. Very well done!
  • This made a ton of sense, thanks for reminding us to keep thinking for ourselves and ask questions! Well done 💖 Looking forward to more!
  • @bridge192
    all your videos are pure gold man, keep it up
  • @robmik83
    The background music is very annoying.
  • Great science.. Was waiting to see the topic of Gluconeogenesis on the body, or how the liver makes the glucose your body needs and the zero requirement for carbs/sugars. Thanks.
  • This video really hit home and I wish I had seen this video 4 years ago. I was overweight and had very bad PCOS. Back then I did smt called the Dukan Diet which is basically an Atkins-Keto-Mix. Then I stumbled across the Keto gurus and man... it ruined me. I reached a peak moment, where I had lost the weight, got rid of the PCOS and even could handle carbs pretty well again, so I started craving them more. Instead of listening to my body, I kept restricting as the Keto gurus preached. It totally ruined me. Had I seen this type of content back then, it would have changed the course of my life for sure. I'm back at the beginning now, having to walk the same path again, losing the same weight again, dealing with the same PCOS and insulin resistance again.... I hope someone else sees this video in time and saves themselve an ordeal

    I dont really agree with the coffee comment. Because, while a lot of low carbers do drink a lot of coffee, most of them have been drinking coffee like this (if not to a greater extent) since before they went low carb. And the people who do eventually stop still find themselves to be energized without it.
  • @mudbrick6083
    Thank you for this great video! I only have one criticism: sometimes, especially during the HALO song part, I can barely hear you over the background music! Thanks for the video.
  • Thank you. I have found low carb to be more tolerable then keto. YOur balanced approach is appreciated here. I am curious what is your net carb target per day? Generally speaking.
  • @adinahwithkaden
    I did end up hypothyroid depriving myself of sugar / carbs. I wish I'd seen this info sooner.
  • @user-bw2vy7vz1q
    Wow, your video is impossibly cool. I questioned myself about the right balance of nutrients in the body, especially metabolically healthy. In my opinion keto-community (and maybe LCHF too) concentrates too much on obesity and insulin-resistance, and don't think about people who are metabolically healthy or who became due to keto. Thank you!
  • @dfms3485
    Excellent video, I repeat, your channel is very underrated.
  • @j.corbygaming
    As somehow who kinda been cheating on keto for around 1-2 months no (Started back in February 11th, 2020, lost over 70 pounds, but gained 20 back. with no exercise and no vitamin or electrolytes refill ment), I now realize that full blown keto is harder to keep up than I thought. For a 270-280 Pound, 6 foot guy like me, what would you recommend for me to loose most of my body fat and try to get some muscle? Always keep up the excellent work man!

    I really like keto and I use it for certain periods of time. But I understand that avoiding carbs isn’t a great plan long term. But I really struggle with my weight and metabolism and I think keto really makes a difference in insulin and hormones. When I do keto I start with almost carnivore and then switch to adding lots of vegetables and a little bit of fruit so I’m still getting a little bit of carbs from that. I keep foods as whole food as possible and I don’t buy “keto” supplements or anything packaged as “keto”. Meat, vegetables, oil, butter, salt, and pepper.
