Intermittent Fasting: Introduction 

Intermittent Fasting Introduction

This eating pattern involves cycling between periods of eating and fasting, with various approaches and schedules to choose from. 

The concept is simple: by restricting the time window in which you eat, you create a calorie deficit and encourage the body to use stored fat for energy.

The appeal of intermittent fasting lies in its simplicity and flexibility, allowing individuals to find a routine that suits their lifestyle. 

Dirty Fasting

Dirty Fasting

There is a modified form of fasting, called “dirty fasting,” which allows a small number of calories during the fasting window to reduce hunger.

Research suggests that this modified approach can still contribute to weight loss, reduced inflammation, blood pressure, and cholesterol levels (1).

Insulin and Fasting

Insulin and Fasting

Insulin is a hormone that regulates blood sugar levels. During fasting, insulin levels decrease, allowing the body to use stored fat for energy. 

This metabolic shift promotes fat-burning and other beneficial processes like autophagy(2).

The Impact of Athletic Greens on Insulin and Fasting

Athletic Greens is a popular green supplement that offers a simple way to supplement your diet with essential nutrients.

However, it’s important to note that Athletic Greens does contain calories from various ingredients, including greens, fruits, and other whole-food extracts.

The Impact of Athletic Greens on Insulin and Fasting

Consuming calories triggers the release of insulin as the body prepares to process and use the incoming energy. Even the modest caloric content of Athletic Greens can stimulate a mild insulin response.

But, if you’re practicing “dirty fasting” you are allowed to consume up to 100 calories in your fasting window.

With only 50 calories per scoop, one serving of Athletic Greens fits well within the range for this modified form of fasting. This means that even though you are technically breaking your fast, incorporating Athletic Greens into your fasting routine could still have plenty of health benefits.

Does Athletic Greens Break A Fast?

Athletic Greens does break a fast as it contains calories. Consuming calories during a fasting window can disrupt the benefits of fasting, so it’s best to avoid consuming Athletic Greens during a fasting period.

Can You Drink Green Juice While Intermittent Fasting?

Can You Drink Green Juice While Intermittent Fasting

As mentioned earlier, consuming any food that contains calories will break your fast. Therefore, drinking green juices during your fasting window will break your fast.

The best approach is to include green juices in your eating window, as this helps prevent an insulin spike and allows you to fully experience the benefits of intermittent fasting.


During fasting, the goal is to maintain low insulin levels to promote fat-burning and other metabolic benefits. Consuming Athletic Greens during the fasting period can lead to a temporary increase in insulin levels, potentially disrupting the fasting state and hindering desired outcomes such as fat-burning and autophagy.


If your fasting protocol focuses on maximizing these metabolic benefits, it is advisable to avoid consuming Athletic Greens during the fasting window.
