Thanks to 17 amino acids, numerous antioxidants, vitamins, and more, wheatgrass has become a popular addition to many people’s diets. But does wheatgrass break a fast?

The answer is not clear-cut. Technically, wheatgrass contains some calories that could break a fast. However, the number of calories in wheatgrass is miniature. It’s unlikely to impact most people’s fasting goals significantly.

So, if you want to get the benefits of wheatgrass while fasting, enjoy it without worry. Always check with your doctor or dietitian first if you have any concerns.

That said, what should you expect when taking wheatgrass during fasting? Does wheatgrass spike insulin? Read on for answers to that and more.

Intermittent Fasting Purpose

Intermittent fasting is a sequence that alternates between fasting and eating periods. The 16/8 approach is the most often used intermittent fasting type.

Intermittent fasting has various functions, including weight loss, reversing insulin resistance, and increasing levels of autophagy.

Loss Some Pounds

Intermittent fasting helps you lose weight by creating a calorie deficit. When you fast, your body has to use stored energy, which leads to weight loss. Intermittent fasting is especially effective for weight loss when combined with a healthy diet and exercise.

Now, when does the body start burning fat during fasting?

Fat burning commences after about 12 hours. However, optimal burning begins after 16 hours up to a day.

Reverse Insulin Resistance

Insulin resistance predisposes you to type-2 diabetes. When you fast, your body has to use stored sugar for energy, which lowers your blood sugar levels. This sugar level reduction helps reverse insulin resistance and improves your overall health.

Intermittent fasting can also help you reach ketosis, a state where your body converts fat to energy.

While there are many superb meals for ketosis, is wheatgrass keto?

Wheatgrass has no fat, one of the critical components of a keto diet. However, it’s an excellent superfood for ketosis due to its low carbs and calories.


Intermittent fasting can also help increase levels of autophagy. This process involves your body breaking down and recycling damaged cells. Autophagy is thought to have health benefits, like reducing the threat of cancer and Alzheimer’s disease.

The Advantages of Intermittent Fasting

Research suggests that intermittent fasting has several health benefits. The top ones include weight loss, improved blood sugar control, reduced inflammation, and enhanced heart health.

Intermittent fasting reduces dementia and Alzheimer’s risk and deters conditions like diabetes and obesity. 

Additionally, intermittent fasting can reduce the severity of allergies and enhance immunity. However, avoid unhealthy meals and overeating during the non-fasting period.

Intermittent fasting can save time and money by eliminating the need for meal preparation and clean-up.

What Exactly Does It Mean to “Break a Fast”?

There are many interpretations of what it means to “break a fast.” In general, it means to end a period of fasting – for religious, health, or other personal reasons. In strict terms, any caloric intake amounts to fast-breaking.

One common interpretation is that you should break your fast gradually. So, if you’ve been fasting for 24 hours, you wouldn’t just dive into a big meal – you would start with something small, like fruit or soup, and then move on to something more substantial.

Other excellent choices to break fast include smoothies, healthy fats, fermented foods, and dried fruits.

Another interpretation is that you should eat whatever you want when you break your fast. This route is more common when fasting for religious reasons, as it’s a time of celebration. 

However, it’s always crucial to keep your goals in mind. Avoid processed foods and excess carbs, especially if attempting weight loss.

Wheatgrass and Fasting

When fasting, it’s important to stay nourished so the body can continue functioning correctly.
