What happens when you drink celery juice for 7 days
I grow celery in my garden and use it very frequently for my meals, particularly to add flavour to soups.
Celery is fantastic in saladas, I love the crunch and usually mix it with walnuts and apple. The mix is fabulous!
But the vibrant green elixir (as in the actual juice from the celery) has taken the wellness world by storm, championed by celebrities and influencers as a “miracle” cure-all.
But what really happens to your body when you commit to drinking 16 ounces of plain celery juice on an empty stomach for a week?
Whether you’re looking to de-bloat or just curious about the hype, here is the breakdown of the 7-day experience.

Phase 1: Days 1–2 (The Adjustment Period)
Don’t expect a sudden burst of energy on day one. In fact, the first thing most people notice is the flavour which is salty, earthy, and quite potent.
- Hydration: Because celery is about 95% water, you’ll likely feel more hydrated immediately.
- Digestion: Celery contains natural sodium cluster salts that can stimulate stomach acid. You might notice your digestion moving a bit faster than usual.
While the boost in digestion is often a goal, be prepared for a “cleansing effect” during the first 48 hours. Because celery juice is high in natural sodium and serves as a mild diuretic, it can act quite quickly on your system. If you have a sensitive stomach, you might want to start with 8 ounces instead of 16 to let your body acclimate without any urgent trips to the bathroom!
Phase 2: Days 3–5 (The “Glow” and the “Go”)
By mid-week, the biological shifts start to become more apparent.
- Reduced Bloating: This is the most commonly reported benefit. Celery acts as a natural diuretic, helping the body flush out excess water and sodium.
- Skin Clarity: While 7 days isn’t enough to “cure” acne, the high antioxidant content (like vitamin K and C) and improved hydration often result in a brighter, more “rested” complexion.
- Increased Regularity: If your fibre intake was low before, the enzymes in the juice may help move things along, though it’s important to note that juicing removes the beneficial fibre found in whole celery.
It’s a bit of a wellness paradox: while the juice helps with regularity, you’re actually removing the insoluble fiber that acts as “fuel” for your gut microbiome.
To keep your digestion truly happy during this week, make sure you’re still eating plenty of whole grains, legumes, or leafy greens during your solid meals.
Think of the juice as your liquid vitamin and your meals as your fiber foundation.
Phase 3: Days 6–7 (The Energy Shift)
As you wrap up the week, you might feel a shift in your morning ritual.
- Morning Clarity: Many people find that replacing a heavy breakfast or a third cup of coffee with celery juice reduces the “brain fog” often associated with morning dehydration.
- Inflammation Support: Celery contains phytonutrients like apigenin and luteolin. While subtle in a week, these compounds work to reduce oxidative stress in the body.
The Reality Check: Myths vs. Facts
With any viral wellness trend, it’s easy for the science to get buried under the hype. While celery juice is a nutrient powerhouse, it is often surrounded by lofty claims that can be a bit misleading.
Before you head to the produce aisle, let’s peel back the layers and separate the genuine physiological benefits from the “miracle” marketing.
| Myth | Reality |
| It’s a “Detox” | Your liver and kidneys already handle detoxing. Celery juice simply supports these organs through hydration and antioxidants. |
| It Cures Everything | It is a nutrient-dense tool, not a replacement for medical treatment or a balanced diet. |
| Juice > Whole Celery | Juicing allows you to consume more nutrients in one sitting, but you lose the fiber that keeps you full and feeds gut bacteria. |
Pro-Tips for Your 7-Day Journey
To get the most out of your week-long commitment, it’s not just about what you’re drinking, but how you drink it.
Preparation and timing play a massive role in how your body absorbs those key nutrients.
To ensure you aren’t just drinking “expensive water,” follow these essential best practices to maximize the potency and freshness of every glass.
- Fresh is Best: Drink it immediately after juicing to prevent the nutrients from oxidizing.
- Empty Stomach: Aim to drink it 15–30 minutes before your first meal for maximum absorption.
- Keep it Pure: To get the purported benefits, don’t mix it with lemon, ginger, or apple—keep it 100% celery.
