Does Celery Juice Break a Fast?

Breaking a fast means you’ll eat something containing calories. This will stop the fat-burning process until another fasting period begins. Some people stay under the 10-calorie limit during a fast, as this can prevent insulin levels from rising.

You should aim to drink celery juice on an empty stomach. The nutrients, like fiber and potassium, may boost your digestive tract. It can also reduce blood sugar levels in those with type 2 diabetes, leading to sustainable insulin production throughout fasting.

Let’s take a look at the nutritional value of celery juice per 100 grams:

  • Net Carbs: 1.37g
  • Total Carbs: 2.97g
  • Fats: 0.17g
  • Protein: 0.69g
  • Calories: 14
  • Fiber: 1.6g
  • Sugars: 1.34g
  • Glycemic Index: 10-15

As you can see, celery juice has the potential to break your fast. The net carbs and calories may kick-start digestive processes and ruin any fat-burning progress. If you still want to have this beverage, consider having only 50 grams to half the calories.

People who want to stay completely strict with their fast should avoid celery juice. You can enjoy drinking it during the eating window when your empty stomach needs a boost. It’s not worth ruining any weight loss results by having one sip of this drink.

If you need more guidance, the DoFasting app has over 5000+ recipes and lots of workouts that get you motivated. There’s a chance to scroll through educational articles that tell you more about what to avoid when fasting and why you should consume whole foods.

Celery Juice Benefits on Intermittent Fasting

A lovely cup of celery juice has many health benefits that can improve your fast. Celery contains many nutrients, including vitamin A, K, and C. All of these combined work to strengthen fat-burning mechanisms and prevent a bad insulin response to fasting.

Below, you’ll find the benefits of celery juice on intermittent fasting:

Hydrating

Since celery is almost 95% water, your body can stay hydrated. This means your immune system and metabolism can work properly when burning stubborn fat. Of course, everyone needs water, but increasing your intake may boost long-term results.

Adults should aim to have at least 8-12 cups of water daily. Celery juice can help contribute to that daily recommendation. If you don’t want to break your fast with this beverage, drink more water instead and snack on celery during the eating window.

Low in sugar

Celery juices, like other types of green juice, contain minimal sugars. You don’t have to worry about future weight gain or raised blood glucose levels. Fructose is the main sugar present in celery, but it still offers many health benefits for intermittent fasting.

Your cells need fructose for energy and aerobic respiration. Not having enough energy could weaken the muscles and stop your metabolism from burning efficient calories. Natural sugars like fructose are perfectly safe to have on your weight loss journey.

Has anti-inflammatory properties

Celery juice can help reduce inflammation in your body.

This may be great for people with autoimmune disorders, fatty liver disease, or inflammatory bowel disease (IBD). The flavonoids in celery protect you against free radicals – unstable atoms that increase the risk of bone or heart disease.

Risks and Downsides to Consider

Of course, there are bound to be downsides to this beverage. Not every drink is suitable for your fast and can promote long-term fat loss. Remember that celery juice has plenty of benefits, but it produces certain risks that might pose a threat to intermittent fasting.

Here are two downsides to consider before drinking this juice:

Contains sodium

Too much sodium in your diet can lead to high blood pressure and digestive issues. This means you have an increased risk of developing heart diseases in the future.

Sodium isn’t always bad, but it’s worth limiting this mineral while losing weight. Celery juice only contains around 88 mg of sodium per cup, so it’s fine to have a small amount each day. You should never exceed 2,300 mg of sodium in your standard diet.

Low in fiber

The body needs fiber to prevent severe constipation and uneasy bowel movements. One cup of celery juice doesn’t have enough dietary fiber to keep blood sugar levels low. If your pancreas produces too much insulin, you’ll no longer be in that fasting state.

Other Drinks to Enjoy During the Fasting Window

Even though celery stalks are good for your health, it might not be worth adding them to a green smoothie. The calories can break your fast and disrupt normal eating patterns. But don’t worry, because there are still drinks to enjoy while fasting.

Let’s take a look at 4 drinks to enjoy that won’t break a fast:

Water

The most obvious beverage is water, as the benefits outweigh most fruit juices. There are no calories, carbohydrates, protein, or sugars that can ruin digestion. It’s a simple drink that flushes out bacteria and transports nutrients and oxygen to your cells.

Coffee and tea

Plain black coffee and tea are great to have during the fast. Not adding sugars or milk brings the amount of calories and carbohydrates right down. For example, one cup (8fl oz) of freshly brewed coffee contains 2 calories and 0 grams of total carbohydrates.

You could also have unsweetened herbal teas. These retain powerful compounds that decrease insulin resistance, especially in those who have diabetes. A single cup of herbal tea has 2 calories (just like coffee) and only 0.48 grams of carbs.

Diluted apple cider vinegar

Apple cider vinegar (ACV) is known to help people lose weight. It can keep blood sugar levels low while you’re in the non-eating window. You should mix one tablespoon of ACV with 16fl oz of water to reduce those horrible hunger cravings.

One tablespoon (15g) only has 3 calories and almost no carbohydrates. Even though it doesn’t taste like sweet apples, it’s much better than eating raw fruits while fasting.

Bone broth

There are lots of bone broth recipes that can fuel your body during a fast. Bone broth usually contains calcium, phosphorus, magnesium, and potassium. All of these important nutrients feed the metabolism and encourage more fat-burning progress.

Consuming bone broth might give you more energy than celery stalks. You just need to be careful of what you include in the recipes, as more calories equals more insulin. Also, you can still pair bone broth with other low-calorie food when you aren’t fasting.
