Can You Drink Celery Juice On Intermittent Fasting? | Smart Sips Only

No—celery juice contains calories, so drinking celery juice during intermittent fasting breaks the fast.

What Counts As A Fasted Drink?

Intermittent fasting means periods with no energy intake. During a fasting window, the goal is zero calories. That keeps insulin low and keeps you squarely in a fasted state. Leading hospital guides say water, carbonated water, black coffee, and unsweetened tea fit that rule.

By contrast, juice contains sugars and contributes calories. Even a lean vegetable like celery gains energy when juiced, because you’re concentrating the plant’s natural carbohydrates into a small glass.

Quick Comparison: Popular Drinks While Fasting

The chart below sets expectations for common picks in a fasting window compared with a cup of celery juice. It’s a practical way to see which choices maintain a strict fast.

Drink	Calories (per cup)	Fasting Status
Water / Seltzer	0	Fasting-friendly
Black Coffee	~2	Fasting-friendly
Unsweetened Tea	~2	Fasting-friendly
Celery Juice (plain)	~22–42	Breaks a fast
Celery Blended Smoothie	Varies	Breaks a fast
Packaged Green Juice	Often 80–140	Breaks a fast

Why Celery Juice Disrupts A Fasting Window

Pressing celery extracts water, minerals, and natural sugars from the stalks. The resulting liquid carries energy. Even at the low end, a cup lands above twenty calories. That’s enough to interrupt a strict fast.

Most styles of time-restricted eating allow only non-calorie liquids. That’s the core idea across daily 16:8 plans and similar schedules described by medical centers. Sipping juice during the off-hours moves the body out of the no-calorie period you planned.

Calories And Carbs At A Glance

Brands vary, and homemade pressing changes numbers, too. Still, reliable databases show a lean range: MyFoodData lists roughly two dozen calories per cup for a basic entry, while other listings run into the thirties. Hospital pages like Hopkins Medicine explain that the fasting window is reserved for zero-calorie drinks, which puts all juices on the eating-window side.

• Generic celery juice: around 22–33 kcal per cup, with a few grams of carbs.
• Brand-labeled celery drinks: often list 30–45 kcal per cup, and blends can run much higher.

Those calories aren’t huge, but they aren’t zero. In a strict plan, any non-zero intake counts as breaking the fast.

Celery Juice During Fasting Hours — Rules That Hold Up

Let’s ground the guidance in simple rules that match what clinicians teach. A fasting window allows water and truly zero-calorie beverages. Anything with measurable energy pushes you into the eating window. That includes vegetable juices, fruit juices, broths, and milk.

Two practical cues help you decide in seconds: first, scan the label for calories; second, check carbs or added sugars. Any positive number means you’ve moved out of a strict fast.

Where Coffee And Tea Fit

Plain coffee and tea land close to zero, which is why they’re common during fasting hours. Watch caffeine if you sip late. You can learn typical amounts in our caffeine in common beverages guide. Additives change the math. A splash of milk or sweetener adds calories, which ends a strict fast.

How To Use Celery Juice Without Derailing Your Plan

There’s a simple way to enjoy the flavor and keep the benefits of time-restricted eating: shift the glass into your eating window. That keeps your fasting hours clean and gives your digestion a clear break.

Smart Timing Ideas

• Use it as a first sip when the window opens, paired with a protein-rich snack.
• Blend stalks with cucumber and lemon during lunch to add volume and hydration.
• If you like a morning ritual, go with water or plain coffee during the fast, then have the juice at your first meal.

Portion, Dilution, And Frequency

A smaller glass softens the calorie load. Diluting one-to-one with chilled water stretches flavor while keeping energy lower per sip. Keep it occasional if weight loss is the goal.

Evidence In Plain Language

Major academic sources explain that fasting hinges on periods without energy intake. They describe acceptable beverages as water and other non-calorie options. That lines up with the logic above. Nutrition databases show celery juice carries calories per cup. Putting those points together gives a clear answer: save the juice for your eating window.

External Checks You Can Trust

Hopkins Medicine describes zero-calorie beverages during the fast, and MyFoodData celery juice shows energy and carbs in a standard cup. Those independent points agree with the guidance here.

Sample Day On A 16:8 Schedule

Here’s a sketch you can adapt. Times are examples; slide the window to suit your routine.

Time	What To Drink/Eat	Reason It Works
7:00–11:30	Water, seltzer, black coffee, plain tea	Zero-calorie liquids keep the fast intact.
12:00	Open window with a small meal; include protein and fiber	Gentle start avoids quick spikes and helps satiety.
12:30	Small glass of celery juice if you like	Fits inside eating window, not the fast.
15:00	Plain water; optional snack with veggies and hummus	Steady energy and hydration.
19:30	Finish dinner; stop calories by 20:00	Leaves a clean overnight fasting stretch.

Buying Or Making Celery Juice

Reading Labels On Bottled Options

Celery-only bottles are rare; many blends add apple, cucumber, or herbs. That spikes carbs and energy compared with straight celery pressing. Aim for short ingredient lists when you want a leaner glass inside the eating window.

Pressing At Home

Fresh stalks with firm ribs deliver the best flavor. Wash, trim, and juice. If the taste runs bitter, cut with chilled water or add a wedge of lemon. Skim foam for a smoother sip. Drink soon after pressing for crisp flavor.

Food Safety And Storage

Keep produce cold, rinse well, and clean juicer parts after use. Store fresh juice in the fridge and finish within a day. Heat isn’t needed here, but a quick boil for tools and bottles helps hygiene if you batch prep.

Side Effects And Who Should Be Careful

Fasting can lead to lightheadedness in the early weeks. Pair clean fasting hours with steady hydration. If you take medications that affect blood sugar or blood pressure, work with your clinician on timing and doses before changing eating schedules.

Celery itself can trigger reactions in people with specific allergies. Large volumes of any juice may unsettle digestion. Start small when you add new drinks to your routine.

Reliable Numbers You Can Use

Energy In A Cup Of Celery Juice

Independent nutrition databases list ~22–42 kcal for a cup, with small amounts of protein and a few grams of carbohydrate. Branded blends climb higher. That range explains why this drink belongs in the eating window, not the fasting window.

What To Drink During A Fast

Zero-calorie choices make the plan easier: water, sparkling water, black coffee, and unsweetened tea. That’s the short menu that keeps the fast clean.

Bottom Line And A Simple Rule

Want the benefits of time-restricted eating and the taste of celery? Keep fasting hours calorie-free. Enjoy celery-based drinks inside the eating window.
