These are such progressive videos. You’ve taught me to experiment on myself because you see it’s so dependent on “your” own metabolism. I got my monitor and my strips and have been learning so much about my body responses. I tested a common sweetener Pyure (stevia/euthritol blend) with no negative responses. But then I tested just black coffee and I saw the same thing. While the sweetener itself didn’t knock me out or spike my sugar, my black fat coffee allowed me to reach 4.5 ketones. That’s therapeutic ketosis! Goodbye sweetener. Thanks for the lesson!!! Amazing teaching.
Rebecca Anderson I never use sweeter and struggle getting above .05. I work a clean program six months now no or little weight loss. But I feel great and refuse to give up. Thank you for sharing.
Great reviews both! I started with black coffee back in Nov 2018 and hated it since I was used to using 5 teaspoons of brown sugar each time I drank coffee which to me is about 3 to 4 cups a day! Well after more than a month of just black coffee, I almost cannot believe I even took sugar with it all these years! I LOVE black coffee now! Folks try it black and you will acquire the taste! If you go black you will never go back! Cheers! :)
Not going to happen here. I’ve tried, but can’t adjust, and don’t enjoy it like I do with 2-3 drops of organic 100% stevia and creamer. My theory is, why drink something you don’t like. More power to you if you like drinking black coffee (I agree it’s healthier).
WOW! Great content, best info yet that I’ve seen . I did not know about the Splenda and thyroid, and I’ve got thyroid issues. So happy you two did this! Thanks soooooo much! 👍🏼
You two are just adorable. I love the chemistry you guys have! Love is a beautiful thing :) Love what you have taught us all in this video! Thank you Doc! :)
Thank you so much for taking the time to do this for everyone. Msybe whoever want to know more about whether or not it loses ketosis should do their own torture test .Your both the best ...THANK YOU AGAIN !!
Thank you for this! I, as others have stated, would be curious on the effects of Truvia, Monk fruit, regular erythritol, xylitol...the natural sweeteners as such. Thank you again for your testings and videos! It's awesome to hear this kind of scientific testing information from Doctors first hand!
Becky's ketone readings are higher because she isn't full time keto. She is low carb according to previous videos. Keith is keto and fat adapted probably, so ketones are probably going to be lower because you are more efficient at using them as fuel. Anyway, thanks for taking the time to test and make the video!
Thank you for this great information and all the time and effort you guys put into this . I would be curious to find out if MCT oil would offset some of the negative effects from the sweeteners. Also, it would be interesting to see how liquid stevia and liquid splenda affect blood sugar and ketone levels.
Interesting test and props to u for doing it. However, the ‘noise’ in BH and K need to be considered. There are random variations in Blood Glucose as well as time-of-day trends that vary by person. My fasting BG (15 hours in) can vary up to 15 points and having consumed no sweeteners. The only way to deal with this is with a much larger sample size.
Thank you guys, for making this video and the first one. I was always curious but didn't have the resources to check. This at least will give me better options on how to do my fast with coffee.
Thank you both! Today I fasted all day, only water. Tonight I had a cup of dandelion tea and one packet of stevia w/ erythritol... 1-2 hrs later I checked my ketone level (strips). They'd dropped by half! Wow. Not good. This maybe a reason my weight loss is so slow, for me anyway. And no cheating. Staying in my macros + IF. I have a few brands. I'll now try my Sweet Leaf that you tested.
Thanks for running the test. I have been using the SweetLeaf stevia extract (super concentrated - a "serving" is 1/80 tsp) with good success. I'm not sure how that compares to the version you used - with inulin as a carrier - but since I'm using just barely enough to hint at sweetness, I'm hoping that my metabolism isn't terribly impacted by it. But I will definitely keep your tests in mind as I proceed. (And by the way...I realized that I'm practically a neighbor! I live a few miles away on the West Shore.)
On today's morning of IF ketosis.. I wanted to try something different.. Just added some aspartame to my acv lemon drink, just before 3 hrs away from my eating window. But later, something unusual happened. I got headache and was dizzy within 2 hours and I didnt experience this before ever.. I was wondering, but didnt bother much and thought of keto flu (even after being on IF for so many days). But now I got my answer.. Am glad I found this experiment.. I basically got kicked out of keto due to the aspartame. My body stopped fueling me. Thats what caused that dizzy headache due to hypoglycemia! God dang I didnt continue it and got cautious.. No more stevia or aspartame on morning drinks during fasting for sure !! Thanks to you doctor for this lovely patient experiment. I hope this reaches all IFers out there..
Great review of the artificial sweeteners and the effects to blood glucose/ ketones and IF. I'm with Keith, can't get past the taste. I'll stick with MCT oil and HC in my coffee.
Good effort. It's the maltodextrin and dextrose which have very high glycemic index that are causing your blood sugars to go up. Even the "pure stevia" sounds like it included fillers because pure stevia extract is 300 times sweeter than sugar. So the "3/8th teaspoon" used would have been equivalent to 112.5 teaspoons of sugar in sweetness. Try these sweeteners in liquid form.
We actually did a benchmark with a tablespoon of sugar and then tested with the equivalent amounts of sweeteners. Here's the sugar video: ruclips.net/video/REb1Wl4fBeg/видео.html
My experience with stevia in coffee matches yours. It is taking me out of ketosis, stalling weight loss, because I drink about 5 cups spread throughout the day. I thought it was the heavy cream, but it is not. Was testing glucose only. Ketone testing tells the true story with stevia for a very insulin-resistant person. Also have not been able to get blood sugars lower than the 110-130 range except occasionally. Trying to stay off Trulicity and statins, which doc already wrote prescriptions for and I have not yet taken. At 1 month checkup that was low enough for doc to give me more time. 3-month checkup on A1c/triglycerides/HDL is tomorrow. 27 lbs down until I stalled out - when I added coffee/cream/stevia back to my diet last month. Struggling not to regain that weight. So glad for this video, thank you!
First, I'm not surprised I chose Equal when I used sweeteners. Second, I very much disliked Tab. One of my sisters went on a Tab, grapefruit and egg diet. She still has a quarter size spot on her scalp with no hair as a direct result of that way of (not) eating. She's now morbidly obese. I'm 69 and fast and cut out the majority of sugar, sweeteners and eat only what I prepare 95% of the time. Go out to eat very occasionally. I'm a two time cancer survivor and am doing all I can to avoid disease. I never thought I'd have coffee without cream and sugar. Here I am drinking black. Thanks for your informative posts!
Excellent test! Would you please test the Splenda Minis tabs whose ingredients are lactose, sucralose, carboxymethyl cellulose, leucine and magnesium stearate. They are tiny and have no fillers and in particular no maltodextrin or dextrose. There are also aspartame tabs that similarly do not include the maltodextrin. I specifically went out and picked up these Splenda tabs after learning about the maltodextrin in the packets. Thanks and keep up the great work!
What about Sucra Drops and Stevia Glycerite Drops? Wow! Didn’t know Splenda was not good for thyroid!!! I lived by that since it came out and 6 months ago I gave it up. I have Hashimoto Disease. That explains how they lowered my meds for the first time from .175 mcg to 112 mcg between Keto and going to Stevia Glycerite and giving that up now too! Waiting for the results of my blood work from Monday to see the thyroid levels if the 112 mcg is the magic number for now . You guys rock !!!
So the takeaway seems to be these things generally don’t raise your blood sugar, but they prevent it from dropping. This makes perfect sense to me. When I used to do IF with Splenda my weight wouldn’t go up but refused to drop
Thank you so much for your informative videos. I have been on a carnivore diet and then switched to keto and just testing things out like you have. I have lost around 15 pounds in weight however I have now stopped losing weight and looking to tweek my diet now to continue losing more weight.
Question: have been told when OMAD, if you drink anything with Stevia (love Sweet Leaf) ie 'if it tastes sweet you break your fast' which has been interpreted as 'will throw you out of ketos' - yet that does not appear to be true from the vid's you'all have been so thoughtful to provide. Okay, truth seems to be in you'all's figures yet others maintain 'nothing that tastes sweet'. Hope this has been expressed clearly.
So hubby and I tested our BG and Ketones with 80z of coffee with 4 drops of stevia (equals 1t of sugar) 1T brain octane oil, 1T butter and a dash of cinnamon. Our results Stevia test 9/22/18 Tricia 7:00am BG 100 Ketones 1.6 7:30am BG 94 Ketones 3.1 8:00am BG 90 Ketones 2.8 9:00am BG 88 Ketones 2.2 Fiano 7:00am BG 98 Ketones 2.0 7:30am BG 93 Ketones 2.3 8:00am BG 96 Ketones 2.7 9:00am BG 82 Ketones 1.9 My questions are... Does stevia effect our BG? We didn’t drink any more coffee during the testing. My concern is I drink more than 8oz of coffee during a 2 hour period. Should I do a test drinking the entire 2 hours?
Love this video!..am wondering if I have both heavy cream and MCT oil in my coffee with stevia, will I be knocked out of ketosis ? The questions continue to haunt you! Xoxo
I really enjoyed this video. Thank you . I use Stevia when I have tea or coffee ☕️ but am gradually cutting back on it. I am learning so much about myself watching your videos. Elizabeth x
Please try Sweet Leaf liquid Stevia during your next round of sweetener tests. Many are saying this one doesn’t effect ketones or glucose levels. Great helpful work here! Zevia Root Beer caused my glucose to spike 35 points. That is sweetened only with Stevia, on the Zevia can ingredient list. Everyone reacts different so everyone needs to know how they individually react. This helps!
I found that when I stopped drinking coffee with stevia in the morning during my fast time, I finally started losing weight. BUT I am able to drink coffee with stevia after lunch and lose weight!
Hi.. i found this really interesting. I do the 16:8 intermittent fasting, i do use Stevia in my coffee and i add almond milk as well. I usually have 2 coffees in the mornings. Does Almond milk affect my fast. I didnt think so but im really not sure??
it took me 4 months to work out that sucralose was making me stall. sucralose was not raising my blood sugar or lowering my ketones but must have been holding up my baseline INSULIN level. have removed it and now back on track
spive21 I had the same issue. I was using like 12-14g of the Da Vinci sugar free syrups for flavor. Thought I'd save money just buying regular coffee instead of all the different flavored ones and flavoring it instead with them, not even a full serving remember. I had a major stall as well even though testing blood sugar on several occasions using it showed only a spike of maybe 5 points in the first half hour and then back to normal. So I stopped using them so they are just there on the coffee bar for company if they want it.
were you using splenda? As this has maltodextrin it in, which will effect you but sucralose on its own, made up n your own dropper shouldnt effect you.
Small suggestion to make this work more relevant: One last test. Include a run with table sugar as a baseline. Black coffee is not really the baseline. People who are real black coffee fans would rather put kerosene in their coffee than ANY sweetener. But many people simply have to have a sweetener of some sort. I think you DID, however proved that ingesting anything - even black coffee - does act to break a ketogenic fast. Maybe that matters only to those trying to IF toward driving down serum insulin.
Please check out these videos. :) ruclips.net/video/REb1Wl4fBeg/видео.html ruclips.net/video/iAv-1UHHjeg/видео.html ruclips.net/video/d87lR4_mmg4/видео.html
Thanks for the reply. This squares the circle. I like your rigorous approach. It is what one should expect of health care pros. Your results are in line with others although they are more intuitive rather than exhaustive like your work. I think there is a lot of personal variability.
Can you test the accuracy of the Precision. Do 4 tests with one minute a part to see the variance. Both glucose and ketones. Thank's for a great channel.
Agreed. It'd be best to show that baseline as - unfortunately - the readings sometimes vary quite a bit even within seconds of eachother and all other variables remaining constant.
I’d think that you’d have to do at least a 7 day test for your baseline levels, and then a 7 day test for each product that you are evaluating just to get a bit more data about each one is affecting your readings. Just doing one day of testing for each thing is too easy to be thrown off by other factors and makes the results less conclusive. I know that’s a lot of testing but it would be much more accurate than just one day per product. Thanks for doing this though, it’s very interesting to watch and gives a lot of food for thought, and also inspiration to test things in ones own body to see how things affect us as individuals.
I've been waiting on this video! Thanks so much for doing this experiement. I really appreciate it! Although as we saw here, results can vary, person-to-person, in general it looks like all sweeteners--even Stevia are not good when fasting (and artificial sweeteners, to no surprise, are still BAD). Looks like I will either kick the coffee habit or give up Stevia in my keto coffee during IF. I will do Stevia only during my eating window.
Awesome video. Thank you for the detailed information. I have recently switched from S&L to pure sucralose (not Splenda). I add literally a pinhead of sucralose and my coffee is perfect - lightly sweet. It also tastes just like sugar - no chemical aftertaste.
I love these videos because I tend to be more like Keith. I test very much like him. I have never had ketone readings as high as Becky's! I admit I am a bit jealous!
What sugar substitute is good for you and taste like sugar? I've been using Splenda and drinking Diet Lipton Green Tea with Aspartame for years. I would like to find something to replace these sugars but taste as sweet as Splenda and Aspartame.
Hey guys, hope you all and Kelly are doing well. I just got a CGM (FreeStyle Libre 3) and it's been a real eye opener. It gives me real time impact and helps tremendously with glucose management. Looks like I'll be moving to black coffee...it will be just like out in the field in the Army again, but at least the coffee will be hot not cold. I had a question about A1C versus the GMI that CGMs compute. I've done a little research on it but was hoping that you might cover that in a future video. I've also read that CKD can really skew A1C results. You may have covered this already, if so I apologize, maybe I just missed it. Anyway, Anessa and Cindy say hi...Duffy
Hi Dr's Becky & Keith Thank you so very much!! No splenda for me for sure...if i bomb occasionally, it will be stevia. Thank you, thank you☆☆☆☆☆ at 191.4 after starting your coaching program! Take care, y'all🙋♀️
Hi Docs. Does it matter if you put half a packet of sweet n low? Will it have a difference or just the same results as you tested with 1 and a half packets? Thanks.
To answer one of your initial posting comments about erythritol, I use erythritol in my coffee, but I drink decaffeinated coffee, because for “me“ caffeine spikes my blood glucose level. Twice a week I mix decaffeinated coffee, heavy cream, ice and water with a squirt of erythritol and it is my Starbucks frap replacement! I find myself looking forward to my twice a week quart of coffee. Remember, everybody is different, so this may not work for you. The only way you will know is to test yourself before and after gulping down this delightful stuff.
Love your videos! You are informative, practical, down-to-earth and so likable! Since doing keto, I am experiencing leg cramps-intense!- almost every morning. It wakes me up in a very unpleasant way. I’m taking calcium citrate and magnesium citrate every night. I take potassium during the day and use pink or grey salt. What am I missing or doing wrong?
Laura Green there are several kinds of magnesium. Magnesium glycinate is more absorbent , they also have an oil and gel.Consider taking vitamin D. Some studies suggest that increasing your vitamin D can help your body to absorb magnesium. Hope this helps
Laura Green yes! Magnesium is so very important! Have you tried also using pink Himalayan salt? Or even using electrolytes? Just trying to help you troubleshoot, though the bottom line is magnesium and the quality of it, that's what's important when supplementing. Jigsaw magnesium is very good Dr. Beckers gel absorbs quickly too.😀
wanda arns Yes, I use either pink Himalayan or grey salt on my food, cream of tartar in my lemon/ACV water for potassium and I take a potassium supplement throughout the day. I take the cal and mag citrate at night currently.
Yes i think a lot of us use the bottled flavoured syrops in our coffee, would love to see the results from those, especially the vanilla flavor,,torani and davinci brands,,,so many wonderful flavours
All the time and effort and pains! You're so precise. And then even did charts! Very generous. Thank you for everything. Diane

I personally just don't add any sweetener to my drinks or food when I'm fasting, just to be sure.
Yaayy for Stevia !! Make sure to choose stevia with inulin instead of maltodextrin.
Maltodextrin is a carb and worse than sugar
I just found your videos a few days ago & really appreciate your test videos like these! Thank you

We didn’t drink any more coffee during the testing. My concern is I drink more than 8oz of coffee during a 2 hour period. Should I do a test drinking the entire 2 hours?
It's possible that stevia may be affecting your results. You can always test stevia yourselves as well as more coffee. :)
Love this video!..am wondering if I have both heavy cream and MCT oil in my coffee with stevia, will I be knocked out of ketosis ? The questions continue to haunt you! Xoxo
Very interesting, thank you doctors. Will you test liquid splenda, ez sweet is the brand I like, and will you test monk fruit. Thank you
Thank you so much for doing this! I have ordered MCT oil for my coffee, but I was really curious about Stevia.
I'm not mad...more like grateful😁Explains why I'm not moving forward. Thanks😉
I really enjoyed this video.
Thank you .
I use Stevia when I have tea or coffee ☕️ but am gradually cutting back on it.
I am learning so much about myself watching your videos.

Your tests are so helpful. Thank you!
Wow! Loved this video. Thank you, docs ! ❤️
Please try Sweet Leaf liquid Stevia during your next round of sweetener tests. Many are saying this one doesn’t effect ketones or glucose levels. Great helpful work here! Zevia Root Beer caused my glucose to spike 35 points. That is sweetened only with Stevia, on the Zevia can ingredient list. Everyone reacts different so everyone needs to know how they individually react. This helps!
Hi guys, thanks for another round of testing. Would stevia liquid have the same effect as the one that you used? 👍🏼
Great work . . .Thanks for the research!
I found that when I stopped drinking coffee with stevia in the morning during my fast time, I finally started losing weight. BUT I am able to drink coffee with stevia after lunch and lose weight!
You captured my attention well.
Good work and word.

Hi.. i found this really interesting. I do the 16:8 intermittent fasting, i do use Stevia in my coffee and i add almond milk as well. I usually have 2 coffees in the mornings. Does Almond milk affect my fast. I didnt think so but im really not sure??
Thanks, Docs. Very good advice
it took me 4 months to work out that sucralose was making me stall. sucralose was not raising my blood sugar or lowering my ketones but must have been holding up my baseline INSULIN level. have removed it and now back on track
spive21 I had the same issue. I was using like 12-14g of the Da Vinci sugar free syrups for flavor. Thought I'd save money just buying regular coffee instead of all the different flavored ones and flavoring it instead with them, not even a full serving remember. I had a major stall as well even though testing blood sugar on several occasions using it showed only a spike of maybe 5 points in the first half hour and then back to normal. So I stopped using them so they are just there on the coffee bar for company if they want it.
Can you test liquid sweeteners? Stevia & sucralose
were you using splenda? As this has maltodextrin it in, which will effect you but sucralose on its own, made up n your own dropper shouldnt effect you.
sucralose based diet soda
i would suggest it wasn't the sucralose, but something in the diet drink causing the issues.
Small suggestion to make this work more relevant: One last test. Include a run with table sugar as a baseline.
Black coffee is not really the baseline. People who are real black coffee fans would rather put kerosene in their coffee than ANY sweetener. But many people simply have to have a sweetener of some sort.
I think you DID, however proved that ingesting anything - even black coffee - does act to break a ketogenic fast. Maybe that matters only to those trying to IF toward driving down serum insulin.

Thanks for the reply. This squares the circle. I like your rigorous approach. It is what one should expect of health care pros.
Your results are in line with others although they are more intuitive rather than exhaustive like your work.
I think there is a lot of personal variability.
Thank you guys for sharing this information. Love your videos!💕
Thank you for doing this testing!!! I know it’s a pain in the finger!!👍💕💚🌸
Can you test the accuracy of the Precision. Do 4 tests with one minute a part to see the variance. Both glucose and ketones.
Thank's for a great channel.
Agreed. It'd be best to show that baseline as - unfortunately - the readings sometimes vary quite a bit even within seconds of eachother and all other variables remaining constant.
I’d think that you’d have to do at least a 7 day test for your baseline levels, and then a 7 day test for each product that you are evaluating just to get a bit more data about each one is affecting your readings. Just doing one day of testing for each thing is too easy to be thrown off by other factors and makes the results less conclusive. I know that’s a lot of testing but it would be much more accurate than just one day per product. Thanks for doing this though, it’s very interesting to watch and gives a lot of food for thought, and also inspiration to test things in ones own body to see how things affect us as individuals.
I've been waiting on this video! Thanks so much for doing this experiement. I really appreciate it! Although as we saw here, results can vary, person-to-person, in general it looks like all sweeteners--even Stevia are not good when fasting (and artificial sweeteners, to no surprise, are still BAD). Looks like I will either kick the coffee habit or give up Stevia in my keto coffee during IF. I will do Stevia only during my eating window.
Awesome video. Thank you for the detailed information. I have recently switched from S&L to pure sucralose (not Splenda). I add literally a pinhead of sucralose and my coffee is perfect - lightly sweet. It also tastes just like sugar - no chemical aftertaste.
This is a fascinating comparison of metabolisms
Hi thanks for the content. Its really great. Can I take sweeteners in my eating window during intermittent fasting?
OMG, more keto coffee tests! Awesome! :)
I love these videos because I tend to be more like Keith. I test very much like him. I have never had ketone readings as high as Becky's! I admit I am a bit jealous!
Thanks so much for doing this! You guys are awesome! I so appreciate it!
Thank you for doing this test!
What sugar substitute is good for you and taste like sugar?
I've been using Splenda and drinking Diet Lipton Green Tea with Aspartame for years.
I would like to find something to replace these sugars but taste as sweet as Splenda and Aspartame.
Swerve
Hey guys, hope you all and Kelly are doing well. I just got a CGM (FreeStyle Libre 3) and it's been a real eye opener. It gives me real time impact and helps tremendously with glucose management. Looks like I'll be moving to black coffee...it will be just like out in the field in the Army again, but at least the coffee will be hot not cold. I had a question about A1C versus the GMI that CGMs compute. I've done a little research on it but was hoping that you might cover that in a future video. I've also read that CKD can really skew A1C results. You may have covered this already, if so I apologize, maybe I just missed it. Anyway, Anessa and Cindy say hi...Duffy
Hi Dr's Becky & Keith Thank you so very much!!
No splenda for me for sure...if i bomb occasionally, it will be stevia.
Thank you, thank you☆☆☆☆☆
at 191.4 after starting your coaching program!
Take care, y'all🙋♀️
Hi Docs. Does it matter if you put half a packet of sweet n low? Will it have a difference or just the same results as you tested with 1 and a half packets? Thanks.
Yucky, yes! You two are taking one for the team!
To answer one of your initial posting comments about erythritol, I use erythritol in my coffee, but I drink decaffeinated coffee, because for “me“ caffeine spikes my blood glucose level. Twice a week I mix decaffeinated coffee, heavy cream, ice and water with a squirt of erythritol and it is my Starbucks frap replacement! I find myself looking forward to my twice a week quart of coffee. Remember, everybody is different, so this may not work for you. The only way you will know is to test yourself before and after gulping down this delightful stuff.
Love your videos! You are informative, practical, down-to-earth and so likable!
Since doing keto, I am experiencing leg cramps-intense!- almost every morning. It wakes me up in a very unpleasant way. I’m taking calcium citrate and magnesium citrate every night. I take potassium during the day and use pink or grey salt. What am I missing or doing wrong?
Laura Green there are several kinds of magnesium. Magnesium glycinate is more absorbent , they also have an oil and gel.Consider taking vitamin D. Some studies suggest that increasing your vitamin D can help your body to absorb magnesium. Hope this helps
wanda arns: I do take a D3/K2 combo. But will def look into the glycinate oil or gel. Should I rub it right into my calves at night before bed?
Laura Green yes! Magnesium is so very important! Have you tried also using pink Himalayan salt? Or even using electrolytes? Just trying to help you troubleshoot, though the bottom line is magnesium and the quality of it, that's what's important when supplementing. Jigsaw magnesium is very good Dr. Beckers gel absorbs quickly too.😀
wanda arns Yes, I use either pink Himalayan or grey salt on my food, cream of tartar in my lemon/ACV water for potassium and I take a potassium supplement throughout the day. I take the cal and mag citrate at night currently.
Yes i think a lot of us use the bottled flavoured syrops in our coffee, would love to see the results from those, especially the vanilla flavor,,torani and davinci brands,,,so many wonderful flavours
The equivalent of 1 tbs of sugar is quite a lot. I wonder what your results would have been with the equivalent of 1 tsp of sugar.
