The definition of 'fast' according to the dictionary is to 'abstain from all or some kinds of food or drink.'
People fast for many reasons including:
Religious purposes
Losing Weight
Chronic Health Issues
So, if being pure, consuming anything will break a fast.
If the point of fasting is to lose weight the aim is to keep your body in a state of ketosis for as long as possible. Ketosis is a state in which your body is using ketones as fuel, which in turn burns fat. In this case the acknowledged rule is that if you consume over 50 calories your body will no longer fast. As wheatgrass juice is very low in calories, about 20kcal per 100ml the in this case it would not be considered breaking a fast.
While breaking a fast, you will not have eaten anything for some time, so the first meal should be light and small. Wheatgrass juice is perfect for this, rich in nutrients and easy to digest it is a healthy way to break a fast.
