Should You Use A Greens Powder While Intermittent Fasting

Intermittent fasting has become a buzzword in the world of health and wellness, offering a myriad of benefits ranging from weight management to mental clarity.

As this lifestyle gains popularity, individuals are seeking innovative ways to enhance their fasting experience, and one intriguing addition to the mix is greens powder – a concentrated blend of nutrient-rich green vegetables.

The question on many minds is, “Should you use a greens powder while intermittent fasting?”

Let’s delve into the vibrant world of greens powder and its potential impact on your intermittent fasting journey.

What Is Greens Powder?

Greens powder are dietary supplements that typically blend various dried and ground green vegetables, fruits, algae, grasses, and other plant-based ingredients. These powders are designed to provide a concentrated source of nutrients, particularly vitamins, minerals, antioxidants, and sometimes enzymes1.

The specific ingredients can vary between different super green drinks and powders, but standard components of super green may include:

  • Leafy Greens: Spinach, kale, spirulina, chlorella, wheatgrass, barley grass, and other green vegetables2.
  • Fruits: Berries, apple, acerola cherry, and other fruit extracts3.
  • Vegetables: Broccoli, carrots, beets, and other vegetable extracts4.
  • Algae: Spirulina and chlorella are common algae included for their nutrient density5.
  • Enzymes: Some formulations may include digestive enzymes to support better absorption of nutrients6.
  • Probiotics: Some green powders contain probiotics, beneficial bacteria supporting gut health7.

Green powders are often marketed as a convenient way to boost nutrient intake, especially for those who may not consume enough fruits and vegetables through their regular diet. They are available in various flavors and can be mixed with water, juice, or added to smoothies.

Benefits Of Greens Powder

While individual formulations may vary, here are some potential benefits associated with the consumption of green powders:

Nutrient Density

Green powders often pack various nutrients, including vitamins, minerals, antioxidants, and phytonutrients. They can provide a convenient way to boost your intake of these essential nutrients, especially if you have a busy lifestyle or find it challenging to consume a wide variety of whole fruits and vegetables8.

Alkalizing Properties

Some proponents claim that green powders can help balance the body’s pH levels, making it more alkaline. Some believe an alkaline environment supports overall health and reduces the risk of certain diseases, although the scientific evidence on this aspect is still limited9.


Green powders offer a convenient and portable way to increase your daily calorie intake from plant-based nutrients. They can be easily mixed with water, juice or added to smoothies, making them a practical option for individuals struggling to meet their daily fruit and vegetable requirements.

Digestive Health

Some green powders include ingredients known for their digestive benefits, such as fiber and probiotics. These components can contribute to a healthy gut microbiome, promoting better digestion and nutrient absorption10.

Energy and Vitality

The nutrient-rich content of green tea and powders may contribute to increased energy levels and a general sense of well-being. This can be attributed to the vitamins, minerals, and other compounds that support various bodily functions11.

Antioxidant Support

Many green powders contain antioxidants, which help combat oxidative stress in the body. Antioxidants protect cells from damage caused by free radicals, potentially reducing the risk of chronic diseases12.


Some green powders are marketed as having detoxifying properties. Ingredients like spirulina and chlorella are believed to aid the body in eliminating toxins. However, the body’s natural detoxification processes primarily involve the liver and kidneys, and the scientific evidence supporting the detox claims of specific ingredients is often limited13.

What Is Intermittent Fasting?

Intermittent fasting (IF) is an eating pattern that alternates between periods of eating and fasting. Unlike traditional diets focusing on what foods to eat, intermittent fasting primarily addresses when to eat and break your fast14. The main idea behind intermittent fasting is to cycle between periods of eating and fasting to induce various metabolic and hormonal changes in the body.

Several popular intermittent fasting methods exist, and individuals may choose the one that best fits their lifestyle and preferences. Here are some common approaches:

  • The 16/8 Method: Also known as the Leangains protocol, this method involves daily fasting for 16 hours and restricting your eating to an 8-hour window. For example, you might eat between 12:00 pm and 8:00 pm and fast from 8:00 pm to 12:00 pm the next day.
  • The 5:2 Diet: In this approach, individuals generally eat five days a week and significantly reduce calorie intake (usually around 500-600 calories) on two non-consecutive days.
  • Eat-Stop-Eat: This method involves fasting 24 hours once or twice a week. For example, you might eat dinner at 7:00 pm and then not eat again until 7:00 pm the next day.
  • Alternate-Day Fasting: As the name suggests, this method involves alternating between days of normal eating and very low-calorie intake or complete fasting.
  • Warrior Diet: This approach involves eating small amounts of raw fruits and vegetables during the day and having one large meal at night within a four-hour eating window.

Benefits Of Intermittent Fasting

Intermittent fasting represents a lifestyle approach that encompasses a wide range of health advantages. Here are some potential benefits associated with intermittent fasting:

Weight Loss

Intermittent fasting can be an effective strategy for weight loss. By eating fewer calories and restricting the eating window, individuals often consume fewer calories, leading to weight loss. Additionally, fasting periods may increase fat oxidation and metabolic rate15.

Improved Insulin Sensitivity

Intermittent fasting may enhance insulin sensitivity, helping the body regulate blood sugar levels more effectively. This can be particularly beneficial for individuals at risk of or with type 2 diabetes16.

Heart Health

Some studies suggest intermittent fasting may contribute to cardiovascular health by improving blood lipid profiles, reducing blood pressure, and decreasing inflammation. These factors are essential for heart disease prevention17.

Cellular Repair and Autophagy

During fasting periods, such as a significant restriction, the body may initiate autophagy, where cells remove and recycle damaged components. This cellular repair mechanism is believed to have various health benefits and may contribute to longevity18.

Brain Health

Intermittent fasting may have positive effects on brain health and cognitive function. It may support the production of brain-derived neurotrophic factor (BDNF), a protein associated with cognitive function, learning, and memory19.

Reduced Inflammation

Chronic inflammation is linked to various diseases, including heart disease and cancer. Intermittent fasting may help reduce inflammation markers in the body, potentially lowering the risk of inflammatory conditions20.


Some animal studies suggest that intermittent fasting could increase lifespan, although more research is needed to determine its effects on human longevity. The mechanisms behind this potential benefit may be related to the positive impact on various health markers21.

Cancer Prevention

While more research is needed, some studies suggest that intermittent fasting may protect against certain types of cancer. The potential mechanisms include improved insulin sensitivity and the reduction of inflammatory markers22.

Should You Use A Greens Powder While Intermittent Fasting

Whether or not you should use a greens powder while intermittent fasting depends on your goals, preferences, and the specific ingredients in the greens powder. Here are some considerations:

Caloric Content

Intermittent fasting generally involves periods of fasting, during which you consume little to no calories. Some green powders may contain more or fewer calories, depending on their ingredients. If you’re following a strict fasting protocol, you may want to choose a low-calorie drinking lean greens or calorie-free greens powder to avoid breaking your fast23.

Nutrient Intake

Greens powder can be a convenient way to supplement your nutrient intake, especially if consuming various fruits and vegetables during your eating window is challenging. They can provide essential vitamins, minerals, antioxidants, and other plant-based nutrients24.


Many green powders are recommended for mixing with water or another liquid. Staying hydrated is essential during fasting periods, and incorporating a greens powder into your water can be a flavorful and nutritious way to enhance your hydration25.

Digestive Comfort

Some people experience digestive discomfort during fasting periods, and greens powders’ fiber and digestive enzymes might be soothing. However, others may find that greens powders’ volume or specific ingredients can cause discomfort. Pay attention to how your body responds to super greens powder alone26.

Other Considerations

Suppose your primary goal during intermittent fasting is autophagy or maximizing the metabolic effects of 5 days of fasting. In that case, it’s generally recommended to stick to water, black coffee, or plain tea during fasting periods. However, if you’re using intermittent fasting as a tool for weight management and overall health, incorporating a greens powder that aligns with your fasting goals can be a personal choice.

Best Time To Drink Greens Powder While Intermittent Fasting

The best time per day to drink greens powder during intermittent fasting may depend on your personal preferences, schedule, and the specific type of intermittent fasting you’re following. Here are a few considerations:

  • During the Eating Window: If you’re following a time-restricted eating pattern, such as the 16/8 method (16 hours of fasting, 8-hour eating window), you can consume your greens powder during your eating window. This ensures you get the nutritional benefits while adhering to the fasting period.
  • As a Breaking-the-Fast Option: Some individuals break a fast with a greens powder drink. This can be a light and easily digestible option to ease into eating without consuming a large meal immediately. It’s important to note that while greens powder may not technically break a fast in calorie intake, it does provide nutrients, so some purists may prefer water during the fasting window.
  • Pre-Workout: If your intermittent fasting schedule aligns with your workout routine, consider consuming greens powder before exercising. The nutrients can provide a natural energy boost without adding many calories.
  • Midday: If you need a nutrient boost in the middle of the day, you can have your greens powder during your eating window. This can help you get essential vitamins and minerals without consuming a meal.
