    This did not help at all. I have no idea what artificial sweeteners each soda brand uses. Does anyone know if Splenda is ok to use for Keto diet.

  2. Su Freidman on March 24, 2023 at 10:04 am

    Dr. Berg,
    You need to start doing a glucous test video on yourself and show us the results. I lost a ton of weight on keto drinking a reasonable amount of diet soda. You are making stuff up to get your youtube clicks.

  3. Ali Obeid on March 24, 2023 at 10:04 am

    If someone knows medicine please confirm if my hypothesis is true:

    Well if that’s true diet soda should lower BG. levels, since insulin is released in the absence of glucose increase, You will trigger increased hepatic glucose output combine this with keto you gonna get into deeper ketosis due to the effect of accelerated hepatic glycogen depletion.

  4. 4TIMESAYEAR on March 24, 2023 at 10:04 am

    Insulin is released in response to sugar. It’s a chemical thing. Diet soda should have no effect. Aspartame is 2 proteins.

  5. Gene Lariv on March 24, 2023 at 10:06 am

    It depends doc.

  6. Rygarisfun on March 24, 2023 at 10:06 am

    Wow, so if you had nothing to eat and you drank Diet Coke it would stimulate insulin release and you could become hypoglycemic and maybe even die!

  7. omar khan on March 24, 2023 at 10:06 am

    Common people you should not be drinking diet sodas or any sodas.

  8. marty3076 on March 24, 2023 at 10:09 am

    So it does spike insulin. Omg so confusing. Some websites say it doesn’t and some don’t but you say it does. I’m just going to stick with water and no alcohol.

  9. David Ryan on March 24, 2023 at 10:09 am

    I’m sorry, Dr. Berg puts out great information but he is just wrong about diet coke. My ketosis is raging and I drink diet coke regularly. If there are no calories I don’t see how the body would stop using fat as an energy source. There has been study after study that says it does not effect blood glucose. I”m ok if you say its going to give us all cancer but please show the proof of how diet coke affects ketosis.

  10. Strider_Knight_Ranger 11 on March 24, 2023 at 10:09 am

    I have almost lost all the weight I want to and am sticking with keto and I will at least still do skipping breakfast for IF, but I think a diet soda every now and then for a treat I will still do because going to the movies and having a Diet Coke is just the best 💖👍

  11. Paul Chaney on March 24, 2023 at 10:09 am

    This is just false, there are countless videos of people taking keystone and blood glucose tests after drinking a diet Coke with almost no effect, most the time it gets better. I am not saying they are good for you but credibility is lost when someone presents false information.

  12. ajadid1 on March 24, 2023 at 10:11 am

    what about brands like Zevia that is sweetened with stevia? I guess that will be ok

  13. Aussie Mick D on March 24, 2023 at 10:14 am

    Thanks for this Eric. I’ve been having 2 to 3 Diet Coke yesterday and noticed I couldn’t sleep all night. Does it affect sleep?

  14. Suzie J on March 24, 2023 at 10:16 am

    Dang!…. watched this after i polished off a can of Pepsi max😋

  15. Permission To Live on March 24, 2023 at 10:16 am

    Wait, what about sucralose?
    I am dying for Crystal Light!

  16. Randy S on March 24, 2023 at 10:17 am

    I am not giving up my diet soda. Thumbs down!

  17. Shawn Howard on March 24, 2023 at 10:17 am

    nothing to back up your statements.

  18. Kat on March 24, 2023 at 10:18 am

    For me personally, I love Diet Coke but when I drink it it gives me cravings that are so intense I need another Diet Coke to satisfy that urge for sweet. So it’s a cycle that I need to avoid.

  19. 1UPAlpha on March 24, 2023 at 10:21 am

    But stevia are ok?

  20. Dominique on March 24, 2023 at 10:22 am

    While I do my best to completely avoid aspartame and sucralose, I just watched another video where a guy did both glucose and ketone tests with his blood … Before, after 5 minutes, again after 1 hour, and then again after 2 hours. ketones actually went up, glucose actually went down. so, doctor, is this your deeply held belief? Or is what you are saying in the video science? The blood tests seem to disagree with what you are saying. Would you please help me understand that?

  21. Dog On Dog Action on March 24, 2023 at 10:22 am

    Stop. It won’t.

  22. lyn priest on March 24, 2023 at 10:22 am

    How long will it take to get rid of sugar feom a can of coke I drank by mistake on keto 😩

  23. Georgia Mathews on March 24, 2023 at 10:23 am

    Aspartame and sucralose don’t spike insulin.

  24. Frankie Cal on March 24, 2023 at 10:23 am

    I don’t agree.

  25. Lhasa Thailand on March 24, 2023 at 10:24 am

    I was really overweight, on my weight loss journey i lost about 1.5kg a week.
    When i added 0Calorie soda i started losing only 1KG a week. Switched of the drink and started losing 1.5kg a week again.

    For me it definately slowed me down.

  26. Brenda and randy king on March 24, 2023 at 10:25 am

    The body assumes the sweetness of the aspartame to be a sugar so there goes up the insulin response doc muscles has videos on this subject look him up

  27. The Real Drunkard Hu on March 24, 2023 at 10:26 am

    Your research links are all broken. I have 2 sited studies demonstrating the lack of impact on insulin response to artificial sweeteners.

  28. Chris Lyon on March 24, 2023 at 10:31 am

    I totally believe it depends on the person! I drink diet Dew on a fast and im im keto adapted ! My keto meter shows great ketones present regardless if i drink diet pop or not !

  29. kung Few on March 24, 2023 at 10:36 am

    When I was a kid they used to put labels on all diet sodas saying Aspartame gives lab rats cancer, that should be a good enough reason to stick to Zevia if you have to have a soda or lemonade/limeade sweetend with Monk fruit sugar or the other keto approved non chemical sweeteners.

  30. Organic Ether on March 24, 2023 at 10:37 am

    Ok so here is the deal I’m super hooked on soda. Is there any kind of soda I can drink that will keep me in ketosis havwnt had soda on a few months and I’m in ketosis but I’m climbing the walls. I feel like pookie in new jack city. I need some soda.

  31. David Wirth on March 24, 2023 at 10:39 am

    I have seen someone measure their sugar before and after consuming different artificial sweeteners and blood sugar went up between 7-10 points over an hour drinking diet soda , coffee , seem to some effect , but very little. I be more concerned about the chemicals etc..

  32. shavaughn1980 on March 24, 2023 at 10:42 am

    What about flavored sparkling water? I love bubbly black berry.

  33. Cobra Fox on March 24, 2023 at 10:44 am

    Sorry. It might take longer but the nasty taste in my mouth from ketosis needs diet mountain dew.

  34. Jeff Sadler on March 24, 2023 at 10:45 am

    What about Crystal Light?

  35. Justin O'Connor on March 24, 2023 at 10:45 am

    People are not understanding it, it slows down ketosis as insulin increases, but doesn’t mean it will knock you out of ketosis. High insulin will slow fat burning. Sweeteners like sucralose will increase insulin.

  36. i like turtles on March 24, 2023 at 10:45 am

    I drank diet mountain dew ( about a liter) everyday for 5 days and gained 8 lbs. Not positive it knocked me out of ketosis but whatever happened it wasn’t good

  37. Frankie Cal on March 24, 2023 at 10:46 am

    Thomas delauer said aspertame was not good for you in the long run but it doesn’t kick you out of ketosis.

  38. Trey Wilson on March 24, 2023 at 10:46 am

    Sooo, does it kill it? or just slow it down?

  39. Abel Villarreal on March 24, 2023 at 10:48 am

    He didn’t say it kicks you out, it just slows you down…. opening Diet Dr. Pepper

  40. Donna Fox on March 24, 2023 at 10:48 am

    So not even one dt. soda a day? (sad face) I found Zevia which is a beverage sweetened with Stevia, can I drink this instead?

  41. M.11 on March 24, 2023 at 10:51 am

    You DID NOT explain why aspartame breaks a fast and stevia doesn’t.

  42. Johnathan DeLeonlopez on March 24, 2023 at 10:52 am

    Lies all lies

  43. Jason Buckman on March 24, 2023 at 10:53 am

    What if a Type 1 Diabetic drinks diet soda and doesn’t take insulin for it?

  44. gerald brewer on March 24, 2023 at 10:55 am

    It did kick me out

  45. Dominique ___ on March 24, 2023 at 10:56 am

    So.. I’ve watched several videos made by Dr. Berg about artificial sweeteners and how they will "kick you out of ketosis." I’ve inquired for him to post the science. I’m weary of videos and blogs telling me how harmful something is for me .. or how good something is for me… when it is someone’s OPINION. And when they refuse to back their opinion with facts and science (not opinion and beliefs), they lose credibility with me.

    So, I’ve taken a week to track my blood glucose levels .. at wakeup .. after by Bullet Proof Coffee (that IS my breakfast) … after lunch .. and after dinner. I take a level pre-meal, and then 60 minutes after a meal, and again 120 minutes after a meal.

    I’m using mg/dl results. According to several websites: 140+ puts one in danger of going out of ketosis. Under 108 is good range. Under 97 is excellent range. And under 83 is optimal.

    Without posting every result .. my average wakeup is between 72 and 81. Average after my BPC, average is between 62 and 80. After lunch or dinner, where I drink diet cola or diet dr. pepper, I’ve peaked at between 94 and 104. I did some control group meals where I did not consume any artificial sweetener. On those occasions, My post-meal reading was between 85 and 97.

    So, while I am concerned about the jump with the aspartame or sucralose, I have still never gone over the "good" range.

    I’m more concerned about the safety of those two chemicals. And there’s way too much falderal on both sides to make any sense or evaluation of safety. I consume them in very limited amounts, because I’m more concerned about the danger of chemical sweeteners. Still, they do not appear to have taken me out of ketosis.

  46. Gene Lariv on March 24, 2023 at 10:57 am

    Sorry but you’re wrong.

  47. THEOvERSiZEDMeATBALL on March 24, 2023 at 10:57 am

    This has been tested and found not to be the case. check this video out on youtube. This man consumes diet soda and checks his ketone levels and it is unaffected. Diet Coke | Is it Keto Friendly? – YouTube

  48. DeeYankeeinTX on March 24, 2023 at 10:58 am

    Disagree.. doesn’t effect insulin levels .. drink a diet soda a day and lose weight weekly doing keto.

  49. kiddiecarbeds on March 24, 2023 at 11:00 am

    i dont get it . . i lost a lot of weight with a strict keto diet but consumed coke zero to keep me at bay and it worked for me .
    others that do the keto test also mention they are not kicked off keto . .

    so why is there so much negativety on coke zero or any diet soda drinkers when the keto users that do drink this beverage dont see any adverse results in there weight and are not kicked of ketosis?

  50. Das Raven on March 24, 2023 at 11:02 am

    Shortest YouTube video with the most depressing information I’ve heard, since starting this diet. No beer AND no Diet Coke? Just shoot me.
