What is Intermittent Fasting? 

Among today’s most popular wellness trends, intermittent fasting has been a game changer for many on their health journey. As opposed to strict diets that tell you what you can and can’t eat, intermittent fasting is simply a set number of hours where you consume all of your calories.

This is called your eating window. The rest of the time is spent in your fasting period where nothing can be eaten. Water and other beverages such as black coffee and green tea are permitted during fasting hours, however anything with a significant number of calories will break your fast. 

Since caloric intake is limited to a specific number of hours (as opposed to eating anytime day or night), many people find themselves losing weight without keeping track of their calories. This is one of the reasons that intermittent fasting works for those who may not have had success on other diets. 

There are many benefits to intermittent fasting outside of weight loss. Studies have shown improvement in areas such as insulin sensitivity, blood pressure, and hormone health in those that have followed intermittent fasting. 

Although there aren’t any specific rules on what to eat while intermittent fasting, healthy foods are encouraged. This includes a diet primarily consisting of whole foods and limiting highly processed and sugary foods.

Smoothies & Intermittent Fasting

Since intermittent fasting is a schedule of when to eat and not what to eat, there can be a lot of questions surrounding the topic of what to eat while intermittent fasting. As mentioned before, smoothies are a great way to break your fast and start your eating window the right way. Not only are smoothies a nutrient-dense source for calorie intake, but they are completely customizable to fit individual needs. 

If you are making smoothies at home, you may be wondering how to make the best smoothies. We will start with the basic categories to include for a balanced and healthy smoothie: 


Greek yogurt, protein powder, or cottage cheese are great options to add more protein to your smoothies. Adding protein will help you to feel fuller longer and keep insulin levels from rising too quickly.

If you are using protein powder, make sure to opt for an unsweetened or low sugar option as there are plenty of protein powders on the market that contain significant amounts of sugar. 

Liquid Base

A liquid base is one of the necessary components of a smoothie. The liquid base can be as basic as water, while other liquids may contribute to more nutrient-dense smoothies. Try a low-sugar liquid such as milk, coconut milk, or unsweetened almond milk. You might even consider using a bone broth if you are going for a more savory smoothie. 

Fruits and/or Vegetables

Including a variety of fruits and vegetables is important in any diet. Choosing low-sugar fruits with greater fiber content (like berries) will not raise blood sugar levels as much as higher sugar fruits (like watermelon). Consuming berries as part of a balanced diet has been shown to reduce insulin resistance in those with diabetes.

Vegetables also make an excellent addition to smoothies, especially if you aren’t getting them as a regular part of your diet. Vegetables such as leafy greens, cooked beets, celery, and cooked carrots can be added to smoothies without compromising on flavor. 

Healthy Fats

Nutrient-dense smoothies wouldn’t be complete without the addition of a healthy fat foods. Things like nut butters, chia seeds, flax seeds, pumpkins seeds, or avocados are an easy way to add excellent sources of fats like omega-3’s. 

Sweetener (optional)

To enhance the flavor or make certain combinations of foods more palatable, some may choose to add a sweetener, for example Monk fruit, to their smoothies. This is totally up to personal taste, as the addition of fruits to a smoothie will already make the smoothie taste sweet. You can use a small amount of maple syrup, honey, or other sweetener of choice to add to your smoothies if needed.
