Because its not enough to cut out virtually every last carb from your diet and load up on fats, people (cough, Kourtney Kardashian, cough) are now sipping on apple cider vinegar in an attempt to boost their fat-burning potential even more.
Kourt famously tried out the keto diet last year and says she drank apple cider vinegar to stay full and curb her sugar cravings, adding one tablespoon ACV to a glass of water 20 minutes after she woke up and before eating dinner.
Hey there, fam! If you’re deep into the keto game or just peekin’ in to see what’s up, you’ve prolly wondered, “Is apple cider vinegar keto friendly?” Well, lemme hit ya with the quick answer right off the bat: heck yeah, it is! Apple cider vinegar (ACV, as we’ll call it) is super low in carbs, makin’ it a solid pick for anyone rockin’ the ketogenic diet. But, of course, there’s more to the story than just a yes or no. I’m gonna break it all down for ya—why it works, how it can boost your keto journey, what to watch out for, and even some dope ways to sneak it into your meals. So, grab a seat, and let’s chat about this tangy lil’ potion!
What’s the Keto Diet All About, Anyways?
Before we dive into ACV, let’s make sure we’re on the same page about the keto diet. If you’re new to this, don’t sweat it—I gotchu. The ketogenic diet is all about switchin’ your body’s fuel source from carbs to fats It’s a high-fat, low-carb way of eatin’ that pushes your body into a state called ketosis. In ketosis, your body burns fat for energy instead of sugar from carbs, which can help with weight loss and a buncha other health perks
Here’s the basic breakdown of how keto works
- Carb intake: Crazy low, usually around 5-10% of your daily calories, or about 25-50 grams of net carbs a day.
- Fat intake: Super high, like 55-60% of your calories. Think avocados, butter, and coconut oil.
- Protein intake: Moderate, sittin’ at 30-35%. You’re eatin’ meat, eggs, and cheese, but not overdoin’ it.
The goal? Keep carbs so low that your body don’t got no choice but to burn fat. That’s why every lil’ thing you eat gets a magnifying glass—will it kick ya out of ketosis? Spoiler ACV won’t, but let’s get into why.
What Even Is Apple Cider Vinegar?
Alright, let’s talk about this funky liquid. Apple cider vinegar ain’t just some random kitchen stuff—it’s got history and a rep for bein’ a health booster. Basically, it’s made by fermentin’ apple juice with yeast and bacteria, turnin’ the sugars into acetic acid. That’s the stuff that gives ACV its sharp taste and smell. A single tablespoon got about 95% water, 5% acetic acid, and tiny bits of minerals like potassium and magnesium. Pretty simple, right?
Now, why do folks rave about it? Well, it’s been used forever—not just for cookin’, but for all kinda home remedies. People swear it helps with everything from weight loss to clearin’ up skin. But for us keto peeps, the big question is: does it mess with our carb limit? Let’s find out.
Why Is Apple Cider Vinegar Keto Friendly?
Here’s the deal: ACV is totally keto-friendly ‘cause it’s got next to no carbs. We’re talkin’ about 0.1 to 1 gram of carbs per tablespoon, dependin’ on the brand. That’s basically nothin’ when you’re keepin’ your daily carbs under 50 grams. You don’t even gotta track it most times! Compare that to somethin’ like soda or even fruit juice, and it’s a no-brainer why ACV fits the bill.
Here’s a lil’ table to show ya what’s in a tablespoon (15 mL) of ACV:
| Nutrient | Amount |
|---|---|
| Calories | 0-3 |
| Total Carbs | 0.1-1 gram |
| Net Carbs | 0.1-1 gram |
| Fat | 0 grams |
| Protein | 0 grams |
See? It’s practically a freebie in the keto world. Since ketosis depends on keepin’ carbs ultra-low, ACV don’t mess with that at all. In fact, it can even help ya stay in fat-burnin’ mode, but more on that in a sec. Just know that whether you’re splashin’ it on a salad or sippin’ it in water, it ain’t gonna throw ya off track.
How Apple Cider Vinegar Boosts Your Keto Game
Now that we know ACV won’t kick ya out of ketosis, let’s chat about why you might wanna add it to your keto lifestyle. This ain’t just about it bein’ low-carb—there’s some legit perks that can level up your health and weight loss goals. I’ve seen pals (and myself, TBH) get some cool results from mixin’ this into the routine. Here’s the good stuff:
- Helps with Weight Loss: One of the biggest reasons folks do keto is to drop pounds, and ACV might give ya an edge. The acetic acid in it can help reduce fat buildup and cut down on body weight. Some small studies I’ve come across say takin’ 1-2 tablespoons a day could shrink your waistline over a few weeks. Not a magic bullet, but a nice lil’ push!
- Keeps Ya Full Longer: Ever get them hunger pangs that make ya wanna cheat with a carb-heavy snack? ACV can help with that. It’s been shown to bump up feelings of fullness, so you’re less likely to overeat. Pair that with keto’s appetite-curbin’ effects from ketones, and you got a double whammy against cravings.
- Balances Blood Sugar: Keto already helps with blood sugar by cuttin’ carbs, but ACV adds to that. It can lower post-meal sugar spikes and improve insulin stuff. For anyone dealin’ with diabetes or just tryin’ to avoid energy crashes, this is a win.
- Supports Heart Health: Low-carb diets like keto can lower bad cholesterol and triglycerides, and guess what? ACV might do the same. It’s got potential to cut down heart disease risks by keepin’ them levels in check. I ain’t sayin’ it’s a cure, but it’s a neat bonus.
- Boosts Gut Health: A healthy gut is everything, y’all. ACV got polyphenols and antimicrobial vibes that can fight off bad bacteria in your tummy and help the good ones grow. Keto also tweaks your gut bugs in a good way, so together, they’re like a power couple for digestion.
- Might Help with Brain Stuff: Keto’s been used for ages to help with brain disorders like epilepsy, and there’s chatter about it protectin’ against stuff like Alzheimer’s. ACV chips in with antioxidants that fight stress on brain cells. I ain’t no doctor, but this combo sounds promisin’ for keepin’ the noggin sharp.
So yeah, ACV ain’t just safe for keto—it’s like a sidekick that can make the ride smoother. I’ve been tossin’ a bit into my water every mornin’, and I swear I feel less bloated and more on point. Could be in my head, but hey, I’ll take it!
Watch Out: The Risks of Apple Cider Vinegar
Now, before ya go chuggin’ a whole bottle of ACV, lemme hit ya with a reality check. This stuff is powerful, and ‘cause it’s so acidic, it can mess ya up if you ain’t careful. I learned this the hard way when I overdid it once and felt like my throat was on fire. Here’s what to watch for:
- Tooth Enamel Damage: ACV is acidic as heck, and if it’s touchin’ your teeth too much, it can wear down the enamel. That’s the protective layer, and once it’s gone, you’re lookin’ at sensitive teeth or worse. Always dilute it, fam!
- Throat or Stomach Irritation: Drinkin’ it straight or takin’ too much can burn your throat or upset your stomach. Some folks even get nausea from the taste alone. I’ve had days where it just didn’t sit right, ya know?
- Low Blood Sugar Risk: Since it messes with blood sugar, it could drop it too low, especially if you’re on meds for diabetes. That’s dangerous, so don’t go wild with it.
- Skin or Allergy Issues: Some peeps get itchy or irritated skin from ACV, especially if ya got sensitive skin. Test a lil’ bit first if you’re usin’ it weird ways.
- Gut Slowdown for Some: If ya got somethin’ like gastroparesis (slow stomach emptyin’), ACV might make it worse. That can lead to feelin’ malnourished or dehydrated, which ain’t fun.
So, how do ya dodge these probs? Easy—don’t overdo it. Stick to 1-2 tablespoons a day max, and always mix it with water or food. I usually dilute a tablespoon in a big ol’ glass of water to cut the bite. Rinse your mouth after, or sip through a straw to keep it off your teeth. And if you’re on meds or got health issues, chat with your doc before makin’ ACV a daily thing. Better safe than sorry, right?
How to Use Apple Cider Vinegar on Keto Like a Pro
Alright, now that we’ve covered the why and the watch-outs, let’s get into the fun part: how to actually use ACV while stayin’ keto. Trust me, it ain’t hard, and it can add some serious zing to your meals. I’ve been playin’ around with this stuff for a while, and here’s my go-to ways to sneak it in without messin’ up my carb count:
- Morning Tonic: Start your day with a lil’ kick. Mix a tablespoon of ACV in a glass of warm water. I sometimes toss in a pinch of cinnamon or a squeeze of lemon to make it less harsh. It wakes me up better than coffee some days!
- Salad Dressin’: Keto salads are life, and ACV makes a killer dressin’. Mix it with olive oil, a bit of mustard, and some herbs for a tangy vibe. Drizzle it over greens, avocado, and grilled chicken—chef’s kiss!
- Marinade Magic: Wanna tenderize meat or seafood? ACV’s your buddy. I whip up a marinade with ACV, garlic, and some keto-friendly spices. Let your chicken or pork sit in it for a few hours, and it’s gonna be juicy as heck.
- Stir-Fry Zing: If you’re makin’ a hot keto stir-fry with veggies and meat, add a splash of ACV for that hot-and-sour twist. It’s amazin’ with broccoli and beef, trust me.
- Sneaky Gummies: For a treat, I’ve even made keto ACV gummies usin’ gelatin and a sweetener like stevia. It’s a weird lil’ dessert, but it gets the job done if ya want a sweet fix with benefits.
Pro tip: go for raw, unfiltered ACV with the “mother” if ya can. That cloudy stuff at the bottom means it’s got extra good bacteria and nutrients. Shake it up before usin’ it. And remember, don’t go past 2 tablespoons a day to keep things safe.
Can Ya Use Other Vinegars on Keto?
Quick sidenote—ACV ain’t the only vinegar out there. If the taste ain’t your jam, or ya just wanna switch it up, there’s other options that are just as keto-friendly. White vinegar and rice vinegar got zero carbs, so they’re even safer in terms of not messin’ with ketosis. They work great in cookin’ too, though they don’t got the same health hype as ACV. I’ve used white vinegar in picklin’ veggies for a keto snack, and it’s clutch. Just somethin’ to think about if ACV’s tang is too much for ya.
What About ACV Supplements or Alternatives?
If straight-up ACV ain’t your vibe, you might be wonderin’ about pills or other stuff. ACV supplements are cool on keto as long as ya check the carb count on the label—some got fillers that sneak in extra carbs. But honestly, I prefer the real deal ‘cause it’s cheaper and I know what I’m gettin’.
Not feelin’ vinegar at all? There’s other keto-friendly boosts ya can try for weight loss. Medium-chain triglyceride (MCT) oil is a big one—it’s pure fat, no carbs, and can help ya get into ketosis faster. I drizzle it on my coffee sometimes for a creamy energy hit. There’s also exogenous ketones, which are like fake ketones ya take to cut hunger. They’re pricier, though, so I stick to basics like ACV most times.
Wrappin’ It Up: Should You Add ACV to Your Keto Life?
So, is apple cider vinegar keto friendly? You bet it is, fam! With its super low carb count, it fits right into the ketogenic diet without a hitch. Plus, it brings some sweet perks like helpin’ with weight loss, keepin’ ya full, balancin’ blood sugar, and even boostin’ gut and heart health. I’ve been usin’ it on and off for ages, and it’s a small change that feels like a big win some days.
But remember, it ain’t all rainbows—ya gotta be smart with it. Dilute it, don’t overdo it, and watch for side effects like tooth damage or tummy troubles. Mix it into your keto meals or drinks with the tips I shared, and you’ll be golden. Whether you’re a keto vet or just startin’, ACV can be a lil’ secret weapon in your toolkit.

So, can drinking apple cider vinegar on the keto diet help you lose more weight?
To be totally honest, researchers just dont know—the science isnt there.
But even if it were, ACVs effects on fat-burning would likely be pretty disappointing. “The overall impact is probably very small, and it’s not really the right focus,” says Mancinelli. “You can probably have the same effect 50 times over if you go on a brisk walk.”
Still, its not necessarily a bad thing to add some apple cider vinegar to your diet—as long as you pair it with food instead of taking straight shots or diluting it in water, says Mancinelli.
“Raw, unpasteurized ACV is fermented and contains probiotics, which we know has benefits,” like improved gut health, says Mancinelli.
The bottom line: You dont need to start taking shots of ACV after every keto meal—the research just isnt there.
First: Why is this even a thing?
Both the keto diet and ACV trends claim to impact fat-burning. The keto diet actually does—youre supposed to cut carbs and load up on fats to go into a state called ketosis, where your body actually starts burning fat for energy instead of carbs.
Apple cider vinegars link to fat-burning, however, isnt quite so solid. A 2009 study in the Journal of Agricultural and Food Chemistry showed that, on a a cellular level, vinegar actually did turn on fat-burning genes—but only in mice.
Another 2009 study published in the journal Bioscience, Biotechnology, and Biochemistry found that taking 15 milliliters of apple cider vinegar per day for three months modestly reduced body weight and belly fat in 175 obese Japanese adults. Still, those results were not conclusive and more research needs to be done.
“If you wanted to extrapolate, you could say that it helps you to burn more fat, but I’m not sure you could come to such a conclusion,” says nutritionist Kristen Mancinelli, R.D. Basically, lots more research needs to be done before we can christen ACV as a magic fan burner…especially in humans.
Its also kind of dicey to drink ACV on the keto diet—it is made of apples, after all, which arent allowed. (You can really only eat these eight low-carb fruits on the keto plan.)
You can drink the vinegar, says Mancinelli (once its turned into an acid, its no longer a carbohydrate), but theres still some residual sugar in it, so drinking a lot of it isnt keto-friendly.
