Curious about whether or not apple cider vinegar will break your fast? If you are doing prolonged fasting or intermittent fasting, apple cider vinegar is a great option to add to your routine. It not only is allowed during fasting, but it can also provide you with some positive benefits and help you get even better results.

In this article, I will cover:


What is apple cider vinegar?

Apple cider vinegar (oftentimes shortened to ACV) is mainly made up of something called acetic acid.

Acetic acid is behind many of the health benefits of this type of vinegar. It is also responsible for the sour, pungent flavor.

You see, vinegar is a fermented product. In fact, the Latin derivation for the word vinegar is "sour wine." Fermentation refers to the breakdown of carbs, sugar, or alcohol by bacteria.

To make this particular kind, bacteria called acetic acid bacteria breaks down the carbohydrates in apples and ferment them. Eventually, this process turns the apple juice into a vinegar that contains acetic acid.

ACV has many positive health benefits, and it may help with things like digestion, blood sugar, and weight loss. You can cook with it, drink it, use it as a salad dressing, and much more.

However, some people are worried about adding it to their diets because they are concerned about the carb content. It is made from apple juice (which is high in sugar and high in carbs), so is it also a high-carb product?


How many carbs are in apple cider vinegar?

If you are doing the keto diet or intermittent fasting, you are very aware of the carbs and calories that you consume.

So you will want to know, how many carbs are you consuming when you drink ACV?

This vinegar does contain carbs. But most of the carbs from the apples disappear when they are broken down in the fermentation process. And it is left with only 0.01 g of carbs per tablespoon.

Compare this to other vinegars, and you'll see that is next to nothing:

Comparably, balsamic and rice vinegar contains a lot more carbohydrates.

However, if you are using just a little bit of any of these options (such as a splash on your salad), they should not be a problem. Just be sure to read labels and be aware. For example, certain balsamic vinegars can be very high in sugar, so you'll want to be careful with your purchases!


Does ACV actually break your fast?

When you are doing intermittent fasting, it can be difficult to know what will break your fast and what won't. For example, will drinking apple cider vinegar in water break your fast, or is it okay?

Apple cider vinegar only contains 0.01 g of carbs. There are barely any carbs or any calories in the small amount of ACV you'd put on a salad or mix into the water as a tonic.

Apple cider vinegar will not really break your fast for more than a nanosecond. So it is safe to drink during fasting.

In fact, it is one of the main liquids I recommend drinking while you fast. I believe that it is one of the best intermittent fasting liquids you can turn to.

If you want to better understand what will break the fast and what won't, check out this blog and video. There, I explain what it means to break a fast and share with you what you can and can't having during your fasting period. This topic can cause some confusion, but I'll break it down to the basics so it is all made clear and simple.


Apple cider vinegar can support weight loss and fasting

So now you can rest assured knowing that this liquid won't disrupt your fast. But did you know that it could actually help your fast, too?

As you've already learned, apple cider vinegar contains a very small amount of carbs. But the interesting thing about ACV is that it also has the ability to support insulin and blood sugar levels. And it can help to improve insulin resistance.

It doesn't just NOT break your fast. It also can help you and provide benefit to you while you are fasting.

You see, anything that helps to decrease insulin and support insulin resistance is great for weight loss. And ACV does just that. Apple cider vinegar is a great companion to fasting, largely due to its positive effects on blood sugar and insulin.

When you drink it, you may notice:

  • Your hunger goes down.
  • You feel full longer between meals.
  • Your energy goes up.
  • Your fat loss is boosted.

The more you can decrease your appetite, curb cravings, and keep full for longer, the better. All of these add up to making fasting more effective. And they'll help you be able to experience greater weight loss and even more health benefits.

This remedy isn't just good for fasting and weight loss. It is also great for whole-body health. Here are some of the top reasons to consider consuming more of it as part of your diet plan.

  1. Aids in digestion. Adding acid to the stomach can help to activate digestive enzymes that speed up your digestion.
  2. Controls pathogens. When you consume ACV, it can help keep microbes in check and prevent overgrowths.
  3. Helps you absorb minerals. You need an acidic stomach to absorb certain nutrients, so drinking this acidic liquid can help.
  4. Can help with gas and bloating. When you drink ACV, it might help relieve these uncomfortable symptoms.
  5. Supports acid reflux and indigestion. Oftentimes, too little stomach acid is the problem at the root of acid reflux. Adding in more acidity can help.
  6. Promotes bile release. Your liver needs acid to produce bile, which is why this drink can help with bile and liver health. Bile is important for fat breakdown.
  7. Helps you break down protein. You need acids to break down proteins and properly digest your food.
  8. Supports healthy blood sugars. This can be a great supplement to take if you have diabetes.
  9. Boosts the immune system. It can activate certain parts of the immune system and help fight pathogens.

The bottom line

Are you doing intermittent fasting and unsure about what is going to break your fast and what isn't?

You don't need to be worried about drinking apple cider vinegar on your fast. In fact, I encourage that you add it to your intermittent fasting and keto diet plan.

It contains a very low carb content that won't break your fast or knock you out of ketosis. Plus, it can actually help you out and boost your fasting results.

For example, ACV can help you go longer between meals, decrease your appetite, support your weight loss efforts, and give you more energy and strength along the way. All of these will help you while you are fasting, so that you can get even more benefit out of the process.

And beyond just fat and weight loss, drinking apple cider vinegar can help keep your body healthy in many other ways, too.
