This video discusses fasting in the context of a ketogenic diet for the purpose of controlling insulin as it relates to obesity. "Some people will do a classic water-only fast, others a modified fat fast, and still others a bone broth fast" Page 202 'The Diabetes Code' Jason Fung, M.D.

What about autophagy and HGH, the two other benefits of post 12-hour fasting? I think Dr Fung said autophagy is not affected by fat but he didn't specify if HGH is affected. I think autophagy would necessarily mean HGH is occurring but I am a lay person and have not investigated the studies.

Some in the autophagy world believe that anything other than water during a fasting period will halt the process and others are a little more liberal in their opinions. Our guess is that HGH, autophagy, gene expression, etc. probably require a more rigorous fast to get the wheels rolling.

2 Fit Docs can I use artificial sweeteners?

Almost 6 months ago to the date I had a small heart attack (98% blockage in my LAD). I'm only 38 and had not been to the Dr in 6 years. When I was in the ER I was told that I was diabetic and later was told my A1C was 10.1. A month after the hospital I lost very little weight was (was about 250) and my glucose numbers were only down a small amount but were very unstable. My meds killed the thought of avoiding food because I would be hypoglycemic often. I decided to try ketosis because I had lost weight doing low carb in the past so keto sounded even better. Today I am 213 lbs and a month ago my A1c was 5.2. I'm not on diabetes meds anymore and my cardiologist couldn't believe my numbers. Just thought I would share. As a small update. Weight is down to 203 and A1c is 5.1. Cholesterol is like 20.

Very Informative! Appreciate all your hard work, the effort, time and sacrifices(pricking your fingers each time you perform tests to benefit us viewers) you both put in, sharing your research, knowledge, scientific and through your personal experiences, creating all these wonderful videos....I'm floured! You 2 fit Drs are amazing!!!

Being a research and analysis nerd, I really appreciate your care and process! I’ve been following a clean keto diet and intermittent fasting for three weeks and the results are so different from when I tried using extra sweeteners and special products. Videos like these are so helpful!

Thank you for doing this experiment! Eye opening and much appreciated that you went through the testing for us!

6 minutes in, I cannot get over how adorable you two are. You just gave me deep peace in my heart. Ok. now the info IN the video: your research is awesome and so useful and exactly what I've been looking for. Thank you!

Multi day production efforts to create and document science based content, then edit and package it into a logical, watchable, entertaining piece is not easy. Just a ton of great info with clear effective production values...the time and creativity put into the content is really appreciated. Thank you.

2 Fit Docs, this was fantastic! Had been struggling with this and didn't want to invest in the blood tests. This solidifies my butter coffee during my fast. Thank you so much!

Clearly, one of the BEST videos on KZread for keto! I WILL share it with everyone I know. Thank you so much 2 fit docs!

recently found you guys and love your videos! Over the past year I've been doing keto/low carb and went from 304 to 228.6 and love it. I've never been on a program where it wasn't a daily struggle until keto and I've been on them all. Love your tests and have started adding MCT oil to my coffee. I've been stalled for the last month or so so hopefully this will help! Showing Dr. Keith's story with my husband who is diabetic and has metabolic syndrome and hoping he will begin to understand. Thanks again!!

Very concise, clear presentation that really explained and demonstrated the facts and science behind it. Really appreciated how organized and succinct it was without a lot of babbling, weird music or hyperbole. Thanks so much guys !

This was heartening to me, as I want to stay in ketosis, which has not only reduced my excess weight slowly, but also reduced the ache in all my joints from the hips down to almost nothing since the end of last summer. However, I really, really love to start my day whenever I wake up and finish meditating with a couple of cups of coffee with cream, even though I don’t usually eat any food until around noon. I am a retired 70-year-old, so I’m usually free to start my day slowly. It’s good to know that the coffee and cream are likely to at worst have no effect on my fasting period. Good job of testing your hypotheses! Thanks for sharing the results!

Fascinating! The differences between you also illustrate (much to poor Keith's frustration) the comparison between someone who is insulin sensitive and insulin resistant so well. You guys are so real, clear and also entertaining!!

Great test! I did the same thing with my Keto Mojo and had the same results. The MCT oil that I only bought last week is certainly the key. It made my keytone levels go from .3-.5 to 1.0-1.1 every morning. And I was starting to drop weight much faster! I wish I had been introduced to MCT sooner. I've been on the mostly carnivore diet for a year now.

Technicaly fats boost ketones yet if one is doing IF for autophagy....it seems that fats break the fast from this point of view. I just finished a 68 hours of fast , no fats at all, my ketone began with 1,5 and finised above 5.6. And feeling great. Keith ...that ketone level so low must make it harder for you to fast as hunger may appear more often. I know...took me 4 months to get rid of insulin resistance but only ketogenic diet was not enough. I began fasting by 18 hours and now even 3 days but easiest is 48 hours once a week.

Thanks Alina - to finish my understanding of what you're passing on: you said it took four months to get rid of insulin resistance. At what point did you count your 4 months? After starting OMAD or doing the 48hr once a week regime? What metrics do you use to state that you are now free of insulin resistance? Do you measure by blood or urine ketones? If you had to go an 18:6 day or a 20:4 day now would you ketones be at 3+ in the morning? Some questions to gain a greater understanding of your experience in healing insulin resistance which is something I believe I have.

Ask yourself why/how a zero calorie, non digested carbohydrate could kick your body out of ketosis. Suppose you were in deep ketosis, and you went on a water and stevia fast? What would happen? Would your liver go apeshit creating glucose to stop you from passing out?

Would love to see this repeated with different amounts of MCT, butter, etc to see if there is tipping points & where max benefits hit -- also how it might play out differently with insulin sensitive person vs. insulin resistant person.

Clearly the results show that coffee plus fat does not knock you two out of ketosis and tends to lower BG. However it seems quite a stretch to state that this means that these manipulations do not break ones "fast". They are just plane not the same though i wish it were true. I do not in fact know (nor any expert) of any test that can be performed to determine if even black coffee metabolically breaks a fast in humans. Does anyone have such information? Dr Longo even will not really answer that question and Rhonda Patrick flat out states that even coffee breaks the circadian rhythm and a fast.

The real benefits of fasting is stimulating autophagy...but coffee and fat is a very small affect on fasting and I doubt you automatically stop all autophagy in your body as soon a a drop of coffee touches your tongue lol In the end you have to decide how you want to run your fast...what you feel comfortable with.... no sense in going into a complete dry fast if it always makes you sad and hungry and miserable right? You are after all trying to improve your life not make it miserable. ;-)

The alcohol opens the blood vessels while the coffee increases blood flow and was found to be as good or better than any medications in preventing and treating stroke victims. The added benefit is that it won't break your fast or knock you out of Ketosis.

Have cut one B/P in half my blood pressure is under 120... oh n thanks for not wasting our time asking to hit the button. I subscribed because you were great..

What I've always heard to be the best benefit of fasting is that it increases (and prolongs) the bodies release of HGH (human growth hormone), which is our natural youth hormone. It always increases at night because we're fasting as we sleep, but the first thing we put into our bodies halts our production of HGH. Ketones and insulin aren't really a factor in what breaks a fast in that case, your HGH production is. I doubt there is a method available to the public where you could easily determine if these fats (or even the coffee itself) breaks this fast, but if you can test these things it would give a much more accurate test result. I'd certainly love to know, because drinking nothing but water for 16 hrs a day would be tedious. Morning coffee with a little cream is what tides me over for the first 5 hrs after I wake up, but I'm not sure it's worth the daily fast if either the coffee or the fat reduces my HGH production. ):

I would LOVE to see you do another test (sorry fingers) of Sweet Leaf stevia, Swerve, Pyure sweeteners AND raw cacao powder. There is SO MUCH controversy regarding these supposedly innocuous sweeteners, and I think it would be a huge benefit to know for certain how they effect fasting. Thanks for the fun & informative video -I loved it!

Terrific experiment guys, I applaud your effort. 2 comments: 1. I don’t agree with the fundamental hypothesis that “not kicking you out of ketosis” and “not elevating glucose” equate to “not breaking a fast.” I think there’s more to it than that. I wonder what would happen if you ate one egg, and then checked measurements. If they were similar ketone and glucose findings, would you conclude an egg doesn’t break the fast? Not sure. 2. The low ketones and higher glucose numbers for the gentleman are indicative of chronic ketosis and adaptive glucose sparing, not insulin resistance. It’s actually a really good thing, and it will take exogenous ketones or MCT to really push up his ketone levels. Again, great work. Much respect for your efforts.

Theoretically, the protein in the egg would boost glucose and would throw a person out of a fasting state. But I agree, I think fasting 0 calorie probably has more nuanced benefits than keeping glucose down/steady, and ketones high. When you consume any type of calorie your body has to do work to process that energy and break it down. The body is a beautiful machine. If your trying to lose weight and using IF to do that then I probably wouldn't recommend the keto-coffee during a fasting period. At that point, I would think your body would use the fat your consuming instead of the fat you have stored to provide the bodies energy. It would be interesting to see over a period of time if a person lost more weight with water fasting vs keto-coffee fasting, as it were.

Tyler Kaufman Would you think a 16oz black coffee with only 4 cals and 0.5 grams of protein would make a difference? Please say no, fasting is not so bad but completely giving up my morning joe would be tough. I drink about 24oz of coffee between 5.30 and 9am.

Anything that would have carbs would release insulin and therefore break your fast. Coffee doesn’t have any carbs.

Hi Becky, I'm 58 yrs old and have never put myself on a low carb diet or really any other diet now that I think of it! But after watching one of your videos yesterday, decided to watch more videos and feel very inspired to go on a low carb diet. I will be going to buy groceries tomorrow so that my husband I can get started. The one thing that will be a huge change for me will be to not put sugar in my morning coffee. I put cream in it too, but no sugar? Out of all the sugary carb things to give up, that one is going to be the hardest.

You guys are amazing.. you help us ofcourse and I love the connection you both have ❤️

Very good BUT and there always seems to be one in the group. "What if" you do a super duper KETONE Coffee with; 1 TBS of MCT Oil, 1 teaspoon of butter, 1/2 teaspoon of CACAO and five drops of Stevia. This is the famous MOCHA blend that Thomas DeLauer hooked me on.

That’s what I do too!

I am new to both “IF” and Keto. I assume when drinking bulletproof coffee, I need to wait to add (butter, MCT, cream) until I reach my eating hours, correct? Or can i have this during my fasting hours?

I think this video is saying you can add these (Heavy cream, MCT OIL and butter) to your coffee and it will NOT take you out of ketosis and won’t raise your glucose levels. So that means - if I understand correctly - that these will not break your fast.

Thank you for doing these tests. There is so much conflicting information about coffee and breaking fast. Facts matter! We have enjoyed your channel and calm and reasoning support for a healthy low carb and keto diets. Please keep up these videos 👍🏼
