Artificial Sweeteners* may throw you off ketose

Recommended Posts

Since a 10 month, Im living consistently  on a LCHF diet. A relatively liberal one allowing me up to 50g carbs a day, still keeping ketose.  And I do experimentate quite friskly with resistant starch.  Yet  I have no difficulty to remain in ketose,   Thus, as far as I know, unbroken ketose during all these months.    I suppose my two good hours of exercise almost every day helps me.


A month ago I did bought a bottle of Trocadero Zero;  a sort of fruity Coke soda,  sweetened with aspartam and acesulfam-K.  But no carbs.    I drank 3 small glasses, less than half a liter.

Next morning, my scale was a half kilogramme up (1 pound).  Next evening the scale showed additional two pounds more!  Broken scale??  But I did remembered, the other time I did bought Trocadero Zero,  I too gained a pound...  So it was no sheer coincidence!   Whattsa matter?  A bad batch containing sugar?  Or a batch where they put on wrong label?? And it was really regular Trocadero with sugar?   Both bottles were bought in my local shop.

I mailed to "my brother in LCHF";  really my son living in another city, whom too is on LCHF...  He told me; the batch was prob OK, but several "Gurus" had reported some people do react on aspartam + Acesulfam-K... They get blood sugar spikes...  And may add a pound or two for a couple of days...


OK.  I leave the Trocadero to my wife whom is holding a common low carb diet, but no keto.  And proceed with my usual keto diet.... Three days later I got dizzy a couple of days.  Ie exact the symptom I got when my ketosis began once upon a time...

Ergo:  Warning for artificially sweeteners!   Esp Aspartam + Acesulfam-K, but possibly also others artificial sweeteners.

This  barely 500 ml  of sweetened soda threw me out of ketosis!!!    If I did drank  500 ml of the regular sugar Trocadero or Coke, it would hardly throw me out of ketosis!



1.  Do avoid artificial sweeteners*.  They may be OK for people whom just want to avoid sugar for diet reasons to spare on the calories,  but they is no good  for us ketosians!

IF you really are dying for a sweetened soda, its probably less bad to drink the regular thing...  Ie this soda sweetened by sugar...  


2.   Do not try to be sneaky, and drink juices sweetened with artificial sweeteners*...  Juice may be healthy, but this is a bad compromise.

Its probably much better if you eat a little of real fruit... A half apple?   You will get all the vitamines while they are still fresh, and also the healthy pulp and fibers, and other parts in fruit - but not always present in premade juice... 

You must of course beware the usual 50g carb limit.    Observe fibers is free quota; they dont need to count in the carbos, as they pass directly through the intestines.



*Remark:  There are some OK sweeteners.  Stevia is wellknown to be OK, possibly even healthy.  Monk fruit, and some others are OK too.  The brand of Nicks  is making good sweeteners for consuments to cook on.  Sweets and even ice-cream... There are surely others good producents.

 But unless you know for sure a sweetener is OK, do avoid it.

I once had a naturopath tell me when I was a smoker that he’d rather see me give up artificial sweetener before cigarettes. That the chemicals in those drinks will make me sick! 
I found that quite scary and something I’ll never forget.

apparently it’s something to do with the link to MS and other problems.

Can anyone help with gyms id like the gym to have -proper thai training with good trainers not all touristy but not super old school.  -Thai and western fighters so trainers can work with westerners but it’s not full of tourists -opportunity to fight at end of month  -accom in gym or very close  -dosnt need to be super clinch focused but good clinch as thats my weakness  -good trainers with good instruction for westerners  -preferably in Chang Mai as it’s the cheapest and on a budget -don’t need all fancy equipment and stuff  I like the look of santai Muay Thai, hongthong and boon lanna if anyone has experience with them? Thanks for anyone who can help. 
    • Question for Sylvie! When you made the transition to Southpaw….I’m assuming all of your orthodox combos and strikes had a natural flow to them because that was first for you. ..Im wondering how long it took to get a that natural flow in your Southpaw stance?  Also,  if you have any tips on the transition other constant practice in southpaw. Either way thank you for reading this. Have an amazing day!    - Mike C. 
    • I've read that internal and external martial artists are striving for the same goal, just in opposite directions. The external artists train the form and refine the technique, strengthening the body from the outside in. The internal martial artists trains the structure and refines the technique, strengthening the body from the inside. In that way, external arts would be working with colors and the internal artists would be working with line drawings. Both can make a complete picture but both together would be a powerful combination. I'm a stroke survivor that's always been into fitness. I've also had the unfortunate luck of being in a physical altercation while in my current condition. At the the time, i was able to perform optimally. Thankfully he was drunk and we weren't alone but i still had to defend myself initially. Every since then, I've been researching the most effective combination of martial arts to end fights and improve my balance. You ever meet me in real life, you'll learn that I'm a massive nerd. However, I'm also into fitness, so forming this theory has been very interesting. Bruce Lee's approach to the philosophy of the creation of Jeet kune Do was my place to start. However, his mother art was wingchun and he used methods from other systems to make a more comprehensive system, creating the foundation for MMA. The main 2 styles I found were Muay Thai and Yiquan.  I feel Muay Thai is excellent in the sense of a comprehensive striking system and Yiquan requires you to slow your movements down to fine tune the little balance issues i have. I understand i have no real fight experience and that has been an obstacle but i have experience in physical training and am ready to take advice and criticism

    • I can recommend you to visit Kst Muay Thai.. For the Time Being, you can learn the fundamentals of Muay Thai by yourself. That could be done though reading Blogs!! Like Muay Thai Citizen, Fight Supplies, Team Elite etc. But combat sports must be performed with another person. You can develop negative habits that are tough to break if you don't have someone to correct your form. Training with an instructor is by far the most effective way to learn.
    • Hello everybody =) I'm a muaythai researcher from Brazil. I'm looking for information about the best current muaythai trainers in Thailand, unfortunately I didn't find any consistent information.   Can someone help me?
    • I think what's more important than scent is how effective they actually are. In my experience once gloves smell bad, there's no going back. I'd love to find a solution that works.
    • Exceptional display of courage.  Stood up until the end.
    • Hey, I'm familiar with the struggles with partnering with beginners.  Once is a while is fine, but you don't get as much out of the class as you would with someone at your level.  Here are things I've done in the past: 1) ask the advanced women to come help me train (either in class of outside of class)  2) invite the women that are less advanced, but seem keen on learning, to train with me outside of class, say casually for just techniques (I specified no sparring).  Also give them opportunity to suggest what to work on during those times you train together.  The 2nd one was very hard initially for me, as it involved setting up this new group training.   Our gym had ladies' sparring before that ended in disasters, so I tried to steer us away from that.  Also talking to be ppl I don't know and managing multiple new relationships makes me very anxious and mentally exhausted. But that investment of energy pays dividends -  I started this a few years ago and I have a few women from there that developed a lot since and partners when me in class consistently.  We train together outside of class also.  We even met up in parks to train when the gym got shutdown during covid (but small groups outdoor gatherings were allowed).
