For many people looking to boost their health, intermittent fasting has become a popular dietary approach. But one question that often arises is – can you drink green tea while fasting?
Whether you follow a 16/8, 5:2, or alternate day fasting protocol, knowing if green tea will break your fast is crucial. After all, this mighty little beverage packs some serious antioxidant power and potential health benefits you don’t want to miss out on.
In this comprehensive guide, we’ll explore the dos and don’ts of green tea consumption during different types of fasts. We’ll also dive into the unique benefits of green tea that make it worth working into your fasting routine.
The Rules of Fasting and Green Tea
At its core, fasting involves cycling between periods of eating and not eating. The rules vary based on the specific fasting method:
Time-Restricted Eating (16/8, 18/6, 20/4)
With time-restricted eating, you have a set window of time to eat each day, typically 6-8 hours. The remaining hours are a fasting period.
During the fasting window, it’s generally advised to consume zero or minimal calories to reap the full benefits.
Alternate Day Fasting
This approach involves alternating 24-hour fast days with non-fast days when you eat normally.
5:2 Diet
On this plan, you eat regularly for 5 days per week but drastically cut calories for the other 2 days – typically to 500-600 calories.
So where does green tea fit into these different forms of fasting?
The good news is that plain, unsweetened green tea is widely considered acceptable to drink during a fast, regardless of the method.
Since green tea is a zero-calorie beverage (when unsweetened), it will not cause an insulin spike or initiate digestive processes that could break your fast. It can provide a flavorful, antioxidant boost while keeping your body in a fasted state.
However, it’s important to steer clear of adding any milk, sugar, honey or other caloric ingredients to your green tea. These additions could potentially break your fast by introducing calories and initiating an insulin response.
If you’re practicing a stricter fast like alternate day fasting, some sources recommend limiting green tea to the eating windows since it does contain a small amount of calories from antioxidant compounds. But for shorter daily fasts, enjoying green tea is A-OK.
Benefits of Drinking Green Tea While Fasting
Beyond simply being allowed during a fasting period, green tea may actually enhance some of the benefits associated with fasting:
Boosts Antioxidant Intake
Green tea is packed with powerful antioxidants like epigallocatechin gallate (EGCG) that can neutralize free radicals and reduce oxidative stress. Since fasting may deplete antioxidant levels, sipping green tea helps replenish your stores.
Supports Fat Burning
Some research shows green tea’s EGCG and caffeine content can give your metabolism a slight boost and increase fat oxidation, which may enhance the fat-burning effects of fasting.
Enhances Weight Loss
Several studies indicate that green tea consumption, especially during the fasting periods, can amplify weight loss when combined with a fasting diet.
Improves Brain Function
The combination of L-theanine and caffeine in green tea may improve focus, alertness and cognitive performance – a bonus when fasting can sometimes cause brain fog.
Regulates Blood Sugar
Green tea has been shown to increase insulin sensitivity and reduce blood sugar spikes, which may help prevent energy dips and food cravings during a fast.
Potential Anti-Aging Effects
The antioxidants in green tea are theorized to activate the same longevity pathways triggered by fasting and may amplify cellular repair processes.
As you can see, green tea is a complementary addition to almost any fasting protocol. Its low-calorie antioxidant hit can enhance some of the benefits you’re fasting for in the first place.

Matcha Green Tea
As a concentrated powder made from stone-ground whole tea leaves, matcha provides a bigger nutrient punch than standard brewed green tea. It’s especially rich in EGCG.
Sencha
This traditional Japanese green tea is steamed rather than pan-fired, better preserving its antioxidants and amino acid L-theanine.
Gyokuro
Shaded for about 3 weeks before harvest, this high-quality Japanese green tea boasts a vibrant green color, sweet flavor and superior antioxidant levels.
Longjing
One of China’s most prized green teas, Longjing or Dragon Well has a nutty taste and is believed to have anti-aging and fat-burning benefits that complement fasting.
Hojicha
Though not a true green tea, this roasted Japanese tea retains some antioxidants and has a low caffeine content, making it ideal if you prefer less stimulation while fasting.
Best Practices for Green Tea and Fasting
To optimize your experience drinking green tea while fasting, keep these tips in mind:
Hydrate First
Drink a glass of plain water before enjoying your green tea, as the compounds in tea can be dehydrating – something to avoid during a fast.
Time it Right
If your fasting protocol involves calorie windows, have your green tea during your fasting periods, not eating windows.
Brew it Properly
Brew green tea at the right temperature (around 175°F) and steep for 2-3 minutes to extract the maximum antioxidants and nutrients.
Have it Unsweetened
No sugars, milk or other caloric add-ins! Drink your green tea plain, or try a squeeze of fresh lemon or lime if you need some flavor.
Listen to Your Body
Green tea contains caffeine, which could potentially exacerbate side effects like headaches, irritability or energy crashes for some when fasting. Adjust your intake accordingly.
Quality Matters
Spring for loose leaf green teas from reputable brands rather than lower-quality bagged varieties which may contain fewer beneficial compounds.
So in summary – yes, you absolutely can and should drink green tea while fasting! It’s a delicious, healthy way to stay hydrated while potentially enhancing some of the benefits you’re aiming for with your fasting plan.
Just stick to unsweetened varieties, be mindful of your caffeine intake, and take advantage of green tea’s antioxidant richness to get the most out of your fasting efforts.
