    Beginners Guide to Prolonged Fasting | 24-72 Hour Fasting Instructions - Thomas DeLauer
    Stem Cells
    This comes into play after 2-3 days of fasting
    A study from USC found that prolonged fasting (2-3 days) can reset and regenerate the immune system - resulted in the depletion of white blood cells and triggered stem cell-based regeneration of new immune system cells.
    Found that white blood cells are broken down during fasting, which in turn forces the stem cells in your body to produce more - the new white blood cells are not just new, but healthier and more effective than the previous cells
    news.usc.edu/63669/fasting-tri...
    Telomeres
    Telomeres are a protective coating or cap at the end of each chromosomal DNA strand found in your cells
    These protective caps help to preserve your DNA by preventing DNA strands from fraying or clumping together, which can lead to cellular damage, the precursor to disease and accelerated aging
    An enzyme called telomerase can re-lengthen telomeres that are shortened during DNA replication
    Stem cells are the sentinel cells of our body - when our cells incur damage, stem cells swoop in and secrete proteins that initiate the repair process
    When our cells die, they give birth to daughter cells that can replace the cells we lose through a process called differentiation
    The great thing about stem cells is that they express telomerase, so they tend to maintain long telomeres
    Additionally, cells that are born directly from stem cells likely have longer telomeres than cells that aren't, based on the simple fact that they're one cell division away from exposure to high levels of telomerase
    The more stem cells means more daughter cells from those stem cells - daughter cells that come directly from stem cells are a step removed from telomerase, and therefore should have longer telomeres
    www.nature.com/articles/ncomm...
    Ketones
    The body begins, on average, burning ketones between 24 to 48 hours of fasting - BHB, in particular, has been found to benefit the immune system
    A study from the Yale School of Medicine found that exposing human immune cells to BHB following 2 days of fasting resulted in a reduced inflammatory response
    BDNF
    Study published in the journal Applied Physiology Nutrition & Metabolism found that a 48-hour fast upregulated BDNF by ∼ 3.5-fold
    www.ncbi.nlm.nih.gov/pubmed/2...
    Autophagy
    There's no set time for when autophagy kicks in - autophagy is always occuring on some level, but increases when fasting
    So it seems that the length for autophagy should really be based on the length of the other benefits as it'll be occurring alongside them
    How to Start
    4 to 5 days of keto before to make the transition easier - the body's of those who are not fat adapted are reliant upon a constant supply of sugar
    If you jump headfirst into a fast, your body won't be able to efficiently utilize stored fats - when your blood sugar dips, it'll bring about symptoms such as lightheadedness, carb cravings, dizziness, the inability to focus and your usual sugar crash
    How Should I Break My Fast
    Break fast with lean protein at night, then go to bed, and resume normal eating (for extra fat burning)
    Should I Workout
    Low intensity exercise would still be ideal as it's preferable to deplete muscle glycogen, not just liver glycogen
    A main function of glycogen is to maintain a physiological blood glucose concentration, but only liver glycogen directly contributes to release of glucose into the blood
    Skeletal muscles are unable to release glucose (because muscles lack glucose 6-phosphatase) and muscles glycogen is mainly a local energy substrate for exercise, rather than an energy source to maintain blood glucose concentration during fasting
    Muscle glycogen can be broken down to lactate, which can be transported to the liver and via gluconeogenesis in the liver contribute to maintaining euglycemia (Cori cycle)
    However, humans do not show major decrease in muscle glycogen content during fasting - in contrast, the liver glycogen content decreases rapidly during fasting and the liver glycogen content has decreased by ∼65% after 24 h fasting

There is a simple test they can do with an electronic instrument that photographs the back of your eye. Wishing you well.

He has the CGI throughout the video and that gets you more excited because you’re watching little CGI clips of your body going into hyper healing mode lol.

      I’m type 1 diabetic Would a long term fast be too dangerous and create a hypoglycemic situation,? Ones insulin sensitivity could change quickly,Thus basal rate might be to strong and cause low blood sugar.
      I do do intermittent fasting, I skip breakfast. But have a really hard time keeping my blood sugar from going really low when I exercise. Which gets frustrating because I have to have a juice box to prevent low but put the calories back on.😕😕😕

      @@eLm0Panda no you can’t eat whatever you want, if you do you will gain the weight back after the fast. When you break the fast take 2 days straight eat only lean protein whichever you want(I recommend chicken) it’s the leanest, and if you want to fast again then do it after the 2 day refeed. But I like to wait a couple of days extra and have some regular keto food after refeed

    I'm currently at 42hrs...nothing but a little salt, good well water, and a slight smidgen of lemon in every other water I drink. Feel pretty good, it's getting better with each stomach growl but they're getting further between.
    I going for 5 maybe 7 days.
    First time I've done this at all. I'm very unhealthy 28m around 60-70 overweight, ex smoker, severe lung damage from a job site accident. I'm going to die even younger if I don't change.

The plan was to end the fast if there were any issues during training. For sodium I would have a cup of miso at the end of day which I was told wouldn't end my fast. I went all the way, ran a personal best, and completed the fast 2 days later. Our bodies are pretty amazing but we have to know the best way to treat it.

      @@su2sa1li4 Yes Jason is great and he doesn't blatantly push products. That said, I don't blame Thomas for supporting his channel with ethical sponsors provided he actually believes in them. Everyone has to make a living and Thomas does provide great information with professional and highly entertaining videos.

    Awesome & thanks for including a vegan fast- break reference. I'm just beginning my fasting adventures as a vegan, thankfully gluten & soy free as much as possible, and I'm still looking to get the best out of this. I'm grateful for all of your sharing. Cheers

    Great video, thanks! Been fasting for 48 hours now and I start to feel a bit of beautiful "high" in my brain. Will try to aim for 72 hours. Very well done video with simple but powerful advices. 🙏

    I just finished my 3 day fast and was heavily contemplating extending it, but seeing as the returns diminish, I'm breaking it now (day 4).

    I am doing my first 48 hr fast. I started with 5 days of OMAD, and at 40 hrs I am not even slightly hungry. The science works and the weight has been falling off. 22 lbs in a month. 👍

    I'm just coming to the end of a 24 hour fast, since I started Keto 2 months ago I am not hungry. Such a great feeling and I love finally being in control of my eating! Perhaps I will brave 48 hours next week. I've lost 14 pounds so far :)
