Why Does Blood Sugar Go Up When Fasting? 

This really helped. I did keto for 3 years. Then has the most stressful year. Made decision to move with my son and his family. They lived in Europe for 12 years and were returning to states. Their children had never lived in states. Did not know where we were going until May. Sold everything and my home. Lots of decisions. My A1c went from 6.4 to 8.3. Moved and ate what family was eating. Sugars were everywhere. Last month decided to do keto and moving toward carnivore. Just as aside… in December started a UTI that did not respond to meds. In mid January was given cipro. Terrible reaction. A week later I could not breathe. Blood clots in both lungs. Now 3 months later I am feeling so much better. My BS has been up and down. The last 10 days my morning sugars are getting higher. This morning 170. When I went to bed it was 115. I am losing weight and inches. This video helped so much because now I think old sugar is being dumped from liver and the rest of my body. See my new primary doctor next week and hope he will not push meds. Thank you for giving me a place to vent. No one may read this but I feel better putting thoughts on paper. 🌻

Thank you! I was 8hrs away from finishing my first 48 hr. fast when I noticed my glucose level was 144. The next morning it was 90. It was very rewarding to have been able to finish.

SO glad I found this video. I am 71 years old and prediabetic. Both of my parents had diabetes and both had a leg amputated as a result. Both died of complications from diabetes - heart attack and congestive heart failure. I want to reverse this before it gets worse. So, I have been following a low carb diet (not keto for now) and IF (18:6) with one day a week of a 36+ hour fast (beginning post dinner on day 1 through day 2 and ending with a late breakfast on day 3). The first 2 months I saw gradually improving blood sugars and lost 13 pounds. However, starting with the 3rd month, my fasting number began rising. And it got way worse for several days after donating blood. (I do double red cell donation 3X/year). In desperation, I began looking through my youtube subscriptions (yes, I am a subscriber)for a possible explanation. Found this one, viewed it, and now feel less panicked. The message I got from this video is that my body has burned through the sugar that was in my blood and now is starting to burn the stored sugar in my liver and muscles. This has encouraged me to stay the course because I realize that I need to use up that stored sugar before I can begin to see lower fasting glucose numbers. I just need to be patient and keep to my low carb (under 50g/day) diet and IF schedule. Hopefully, I will see improving numbers in the next few weeks. I have renewed determination to stay the course. Thank you.

This video made me cry happy tears. I’ve been so unbelievably discouraged by my blood sugar rising despite doing everything I can to fast and lower my carb load. Thank you as always Dr Mindy for answering my problem

When Aunty Mindy talks about ' your miraculous body '.....it takes away all my insecurities about my plans for fasting and motivates me such a lot.......she gives me confidence....so precious indeed.....i do not need fear in my life.

Hi Doctor...I have been fasting for 3 days and my sugar is rising. This is how I ended up here. Thank you for your explanation in such a simple but direct way. Thank you. You have a new subscriber.

Im on the way to insulin sensitivity and normal blood glucose. Just woke up to a beautiful sunrise on my special day. Reviewed my progress over the last 9 months of the fasting lifestyle. started the journey at 93-94 kg and an HbA1c of 15.8. after 3 months without metformin due to severe side effects to an HbA1c of 9.8 after 6 months HbA1c of 7.1 and now 9 months down to an HbA1c of 6.4 my weight now is 74-75 kg. Tomorrow will be taking out stitches from my big toe. Which changed my lifestyle for 3 weeks due to recovery and reduction of exercise. Its amazing that you can get your health , vitality and youth back even later in life. May the blessings be.

This made me cry cause I’ve been fasting for months n my fasting sugar has been going up and up and I thought I was going diabetic. Thank you thank you I hope it starts going down soon

It has taken me over 2 months of fasting to start seeing a drop in my fasting glucose. I have been a DM II w/ insulin dependence for 23 years. So I am very much aware it will take time to reset my system back.

This helped so much. I’ve gotten discouraged with testing my blood sugar because I would test while fasted and eating low carb and it would still be 109-116.

New member. Yes, my resting BS is in the mid 170''s, This explanation is priceless as I used to think "Nothing is working" when in fact things are going well.

So glad you filmed this, exactly what I needed to know. Just did a 48 hr. Fast but whenever I tested glucose it always was above 100 especially in the morning. Now I understand why. Thank you!

I have been fasting for 60 hours and have not gotten into ketosis yet. This video really helped me understand what is happening. Thank you.

Thank you so much!! I just started fasting (after reading "Fast Like a Girl" 😍) and I was so bummed and a little scared of my BG readings during my fast because I've been working so hard on my carnivore WOE and my blood sugars have been finally coming down to reasonable levels! This video gives me the information and hope I need to keep going! Thank you!!! 🙏🥰✌️

Thank you so much dr this video has given me the answers I need, I have uncontrolled type 2 diabetes and it's been 2 weeks of intermittent fasting no carbs, no sugar and exercise. My glucose has been high everytime I test my sugar. I'm committed to keep my fasting and I hope that my body does what it needs to do to heal and help with my insulin resistance I'm hoping with in time of keeping healthy my stored sugar from years of eating junk leaves my body and I will be more healthy for the sake of living longer for my kids🙏💙

Love your fast training weeks. This is my 4th time joining you. I really like mixing up the different fasts. Thanks

Wow thank you so much for this information. I'm on my 3rd day of water fasting and I could not understand why my blood glucose Kept going up. So I got on youtube and ask this question and you came up🥰 I have been diagnosed with prediabetes and I wanted a holistic way of healing myself. So I started fasting after doing some research. So thank you very much you absolutely answered my question.

I’ve been puzzled by this! Thanks for this video

Very important info there, Dr Mindy! Excellent video! Thank you!🙏🏼

Companion guide. Thanks for all you do.

Companion Guides Please and Thank you ! Team Pelz is Just as AWESOME as Dr. Pelz! Love you all and all that you’re doing to make this a better planet!

Thanks Dr Mindy! Companion Guide. Great information.

Hi I've been following your protocols for some time. As I'm diabetic type 2 and suffer from other health issues such as sleep apnea and emphysema. I've lost lots of body fat following your guidance and really appreciate your explanation on this matter. Easy to understand and informative. Thank you so so much for caring and educating the rest of us. ❤

SOOOO helpful…as always! Thank you, Dr. Mindy! 🥰

Very helpful...especially the part on macular degeneration.. Had no idea that sugar storage was associated in this way with vision.🙏🙏

Hallelujah!!! Thank you Dr Mindy I needed this lecture 🙏🏾💖

Great timing Doc. , I'm going to cure my diabetes with fasting and I've been concerned about my numbers, thanks for putting my mind at ease. 👍

Me too, me too!!!!So glad you filmed this, exactly what I needed to know. Thank you Dr Mindy!!!!

I am expecting this now. My fasting blood sugar is normally in the 84-95 range. This morning for the first time it was at 120. I got nervous because I couldn’t understand what was going wrong. Thank you for the video. I’ve been doing IF and low carb for a few weeks now. I’m definitely seeing positive results. Losing weight, more mental clarity, no joint pain. I’m hoping that my metabolic system is actively in repair mode. 😊

Wow! This was a wonderful paradigm shifting as a result of information! TY

Thank you, Dr. Mindy! I am always learning from you!

I was about to give up, thank you so much for this video. It has truly open my eyes and answered my questions

Companion guide please. Thank you for all you do Dr. Mindy!

Got my sample LMNT pack today. Starting tomorrow and looking forward to it.. Thanks Dr. Mindy for all you do!

Companion guide. Thank you so much for all this important info. that makes so much sense when you explain it.

That makes so much sense, thanks Doc.

Thanks for the info doc. You simplified it nicely!

Stopped keto after 3 days but continuing with intermittent fasting. I’m at 14-16 hours without eating and just 2 meals a day. Today my glucose was rose after working in my yard. I did get exhausted! So I’m resting and reasoning I’m watching this. My blood sugar is lower now! Thank you for your information, I was getting worried!

I just got a ketomojo and this was one of my questions. Thank you!

First off I love Dr. Mindy. At 67, I recently began the intermittent fasting. Today was the first time during a fast that my blood sugar was high, at 107. Immediately I thought the worst. Search med Dr. Mindy high blood sugar during fast and this video came up. Thank goodness I watched it because it made a total difference in my thinking process. And I am currently heading into my 17th hour of fasting and getting ready for my coffee with MCT oil to continue. FASTING GIRLS ROCK!

So glad to get this info!

Companion guide please. Thank you for the wonderful information and the motivation!

Wow, we sure do have miraculous bodies. I am thankful for the support you give us to help us heal

I really needed to understand this, thank you Dr. Mindy 🙏

Oh thank you!! I been 114 I'm like why doesn't it go down... I love fasting. And I have macula degeneration in my left eye...my eye doctor was amazed how it got lot better in a month...doing keto. Thanks for explaining. This .

This speaks volumes! I was wondering why my fasting glucose was 100 with my lab test and my A1C was 5.0..but now I know! Thank you for the information path from Guam!

This is great information. Counter intuitive! Appreciate you explaining this nuance

Thank you for the information.

Hi Dr Mindy. I have been on a water./coffee fast for the past 22 days and it has been a huge learning curve for me, Have lost 10kgs and have listened to a lot of your videos to get guidance. Thank you so much for helping me through this, It has been difficult at times, especially the first few days, but I am determined to fix my painful joints and muscles (the main reason for fasting) my overall health and get back to my ideal weight. Every time I watch one of your videos it helps me to understand what is going on in my body and boosts my determination to keep going! I only just recently bought a Glucose/Ketone monitor and it is the first time I have ever measured my own blood glucose level, but it went up whilst doing my dry fast, so was a bit concerned, but now I know why. But as you explained it, it is pretty logical really, Thank you ever so much! I would love a free copy of the Companion Guide (and the possibilty of receiving a free box of the LMNT) Thank you again. 💞 Just one question... as my eyes are getting better, does that mean the rest of my organs are free of fat/toxins, or does it mean that it is still wotking on them along with the other organs, because my leg muscles and joints are still a bit sore? Oh, sorry, another question ... when dry fasting, is it wise to do exercise, like walking for 15 minutes, as, when I did that it wacked me so much that my body told me to sleep as soon as I got back, and I slept on and off for the rest of the day! So not sure it was good for me?

Companion guide s, thank you 💖🙏

I needed this. I’m 69 y.o. and have been IF for over 2 years. I also went grain and sugar free last year following igG testing and gave up my allergens(gluten, oats, sugar, yeast, chocolate, almonds). I’ve dropped over 60# and am now down to my ideal weight. My fasting glucose is still 103-108 but my A1C dropped from 5.9 to 5.4. I’ve had serious glaucoma causing vision loss for at least 15 years requiring medication and surgical intervention. Three months ago my eye pressure was normal for the first time since they’ve been monitoring it, and yesterday it was tested again and still normal. PTL! I’m completely off medication for asthma and COPD (and symptom free) except for a short time when I had the “Fauci Flu”. All those years of needless suffering eliminated with dietary changes.

Nice info Doc and very encouraging.

Great information, I follow the 18/6 intermittent fasting plan with my eating window of 12noon to 6pm and I feel so good

Another very useful video, thank you so much, Dr. Pelz!!! Free Companion guide please!

I am going through this right now. Cut out the carbs, cut out sugar, and while my overall sugar is decreasing, I notice many times I have an increase in blood sugar from morning to my first meal in the afternoon. Been scratching my head on this, thanks for the clarification!! This will help keep me motivated.

Dear Doctor Mindy: Thank you for this episode. We love this channel here on the Central Coast. You are my Goddess of Metabolic Health.

This a great video!! Very helpful

Just Gold Thanks Dr.

Companion guide. This was so helpful. I’m a type II Diabetic. I always wondered why when I fasted for 24 hours my blood sugar was high. Now I know. Thank you

Thank you, very important information 👍

I subbed INSTANTLY!👍 You answered my question so concisely and in a way that I could clearly understand. My home test was 153 after a 10 hour fast and only had a breakfast egg, bacon, cheese sandwich before work...fasted 10 hours only drinking water at work and a medium sized salad for a very late dinner after getting home from work of organic romaine lettuce, extra virgin olive oil, sunflower seeds, cheese, and sea salt for dinner... checked it 3 hours after dinner and was 153...guess I expected it to be lower. But you explained wonderfully why it was high and that was very encouraging...thank you Dr. Pelz!👍😊

Yes very helpful DR. Mindy!👍🏼💖🙏🏼🥰

Thank you! I was so confused. Very helpful

This is amazing information. I wear a glucose monitor and thought my body was somehow making its own sugar. Even at night whilst I’m sleeping my blood sugar goes up. So happy to know it’s actually dumping it. Thank you!

Thank you for explaining this! Always sharing your message

Thank you so very much for this video! I was getting very frustrated bc my glucose number was up while I'm fasting. I do keto and intermittent fasting everyday and eat one meal a day (most of the time) but my sugar has been extremely high so I decided to fast. This is my 3rd day fasting. The first day, my sugar was relatively high and all over the place. The 2nd day, morning sugar wasn't but but it went up around 11 AM but started to drop and went up little bit. 3rd day, my morning sugar was 117. This has been the best number in months! Companion guide.

Thank you for explanation. I was about to get worried with my rising blood glucose levels in fasted state! You are amazing and I thank God for all the information I have gathered from you.

Doctor Mindy, I wish to God there was a way to literally send this to MYSELF once a week. Yes.,,,and I am still working on this ….six weeks so far. Ty for helping me be patient with my numbers. So so so much.😊

Thank You 🙏 endless blessings to you and your family

Thank you for this video. It is a good confirmation!🙏🏼

Waw this really amazing. I experience this too was thinking was getting things done right but with this perfect explanation I have no choice than to keep up

Thank you. Thank you. Thank you.

Thank YOU so much for this!! I’ve been dealing with higher bs and was getting very discouraged! I will persevere!

Thank you for short concise crucial information that really does help! So tired of these long winded story tellers that never get to the point, then.... want you to click on anther page just to string you along ! You Rock Dr. Mindy Pelz !!!

Thank you. I am new to fasting. I hand this problem. Great information.

New to fasting- I took my reading today/ this happen so I looked you up. Thank you for helping!!!!

Thanks for this, very interesting. Companion guide please

Awesome video Dr Mindy! I have had Type 2 diabetes for about 15 years. It's a long story, but I have been working on it with non-mainstream (ie no medication) methods for years and continuously learning about it. I was not managing well a few years ago and my fasting glucose was 13-15 mmoL/L (235-270 mg/dL). I saw a GP (MD) and they were shocked. I started to get mild retinopathy and then knew I had to do something urgently. Against the doctor's advice, I did not take medication and arrived at eliminating all carbohydrates and continuing with fasting that I have been practising for years. My glucose levels are after ~6 months of this tend to be 5-8 mmoL/L but they do spike to 10-12 mmoL/L (180-215 mg/dL) on occasion and sometimes after significant fasting. I suspect that my body is "dumping" glucose from higher level stores as you describe (ie #2-6).

Top effort of your report

Great info! Thanks for sharing! I got the Companion Guide through email. I’ve been living a fasting lifestyle for a few years to help me manage post menopause life. Mineral deficiency is of concern. Not being from USA prompts a decision on spending the $ for currency exchange, shipping, + perhaps customs fees above product cost. Trying to navigate with local product. Finally splurged on Keto-Mojo and it claims my BG trends

I haven't checked my blood sugar, but successfully lost 50lb on the keto diet along with intermittent fasting. I enjoy what I'm learning on your videos & am interested in your companion guide.

Companion guide please. Love you video

So helpful

Glad I saw this video, I've been practicing IF for just over two weeks and my glucose readings have dropped, but still are over 120. This makes sense now and I just need to give it more time. Thank you for making these videos. 🙏

Hi. I looked glucose dump today after KetMojo testing (4) times during a 49.5 hour fast. I've been fasting since February 8th, 24, and varying the windows. This is the 1st time my highest glucose reading was 129 after 30 hours. I'm enjoying learning about my body and have lost 24lbs since starting Keto. All my clothes are baggy. Yay !!! Thank you, Dr. Mindy.

Thank you for this information! It totally makes sense. I would also love a companion guide. Thank you!!

Thank you ❤️

I’m so glad I found this video. I was getting discourage about the sugar going up or staying the same during fasting. Thank you!

I needed this information today!

Great video.

Great explanation. My bgs are good during the day while fasting but are spiking throughout the night. Many videos talk about the dawn phenomenon but the spike is not in the morning, its throughout the night. I liked your explanation and will continue to monitor.

Companion Guide. Thank you so very much. I’m dealing with this right now. Was so discouraged until I watched this♥️♥️♥️♥️

This is excellent. Thank you for defining a fasting glucose as there are so many ranges if you look for a simple answer, the worst being, "it depends." The explanation makes perfect sense and is a relief knowing this is occurring. Been strict keto for almost a month now and morning blood sugars are still > 100. However, I've also been T2D for almost 22 years, trying to control it with every diet on the face of the earth and inconsistent exercise with all kinds of failure until keto. Keto and IF rock.

Thank you this answered my question!!! Had to subscribe

Amazing information ❤

This video is giving us valuable information that is hard to find.

Hello! Thank you for this important information, at least very important to me. I have just learned that I am diabetic and have just started monitoring blood sugars. For around two weeks, blood sugars have been fluctuating upon waking, in a fasted state: 190, 121, 171, 121. But before going to sleep it has been as low, as, for me so far, 108. Yes, I have also started a carnivore diet, which by the way, has helped with a whole host of issues. While for me intermittent fasting has been easy, insomnia has been a regular visitor ever since perimenopause and menopause. Thank you for sharing your research with us. Yes, have ordered "Fasting Like a Girl" in order to gain more control and understanding.

Hi Dr. Pelz, thank you for such clear explanation of what's going on with blood sugars. I have been fasting for years but recently I had a root canal and took over the counter Motrin. Because it is so harsh on the stomach I ate every four to six hours for 3 to 4 days. Now since I'm back in fasting mode, I noticed that my blood sugar is rising and I was getting so disturbed. This has given me an understanding that I would have otherwise not have known. Thank you again!

great, explanation

So helpful Dr, thank you
