Is it okay to drink diet soda while on a keto diet?

[Iamconnor1223]

I am so conflicted right now. I don't seem to be having any side effects to aspartame. I see people saying "Oh, it's bad. It will spike your insulin and ruin your keto diet. Dr.Atkin advices against diet soda" and on the other had I see people saying "Not much study has been done with stuff like that. I drink *random ammount* a day of diet soda and I still continue to lose fat on a keto diet."
Here's what I am asking:
Can I drink diet soda (artificially sweetened with aspartame) on my keto diet? Will diet soda stop be from being in a state of ketosis and will it spike my insulin? Is Splenda okay to eat also?
Thanks!

I'll let you in on a secret. Ketosis is not the secret to fat loss, calorie deficit is. Ketosis is just the body primarily using fats as energy, whether dietary fat or body fat. HOWEVER... The health/mental benefits of ketosis are many!

But to answer your question, I've heard that artificial sweeteners can temporarily spike insulin because of the "expectation of glucose" because of the sweetness. But even if that did kick you out of keto, you'd be out for all of an hour or so.

It's never okay to drink diet soda. Like never ever. Why put that poison in your body? Grab some flavored Polar seltzer water instead.

You can drink soda. I do it and ive done keto 4 times in 6 month increments. I would stick to coke zero thats my favorite or Pepsi Max. You can even drink sugar free Rockstar. It never knocked me out of ketosis. As long as zero carbs u good

I drink diet soda every day, sometimes a whole 2 L. Lost 104 lbs total so far, 70+ on keto. I put splenda in my coffee, and diet dew has splenda as well.

I feel much healthier today than I ever did at 300 lbs.

I've been doing Keto for quite a while now (2 years, on and off for various reasons), and I've never had a problem with Diet Soda. I don't currently drink soda, however, I replaced it with tea!

I used to drink plenty of Diet Soda, usually Coke Zero, Publix Lemon-Lime Soda, and Monster Absolutely Zero. I was not keto out of keto even once because of these drinks. I think that they can even be quite beneficial to people that have self control issues on keto. It's a keto-safe way to satisfy your sweet tooth.

Also, protip: GingerAle + Heavy Cream = Amazing.

Yes you can, better if you stick to water, green tea, or coffee.

Diet soda or coke zero hasn't knocked me out of ketosis the few times I've had it. A "liquid" saver for me was crystal light as it also has aspartame in it...still in ketosis.

Wrong. This will never occur at physiological doses, even for Ace-K

Wrong. Splenda can kick you out of ketosis because it uses maltodextrin as a bulking agent. Diet mountain dew has no built-in maltodextrin and thus cannot kick you out of ketosis/

What poison? Do you have phenylketonuria?
