Green smoothie and fasting

Awhile back I was doing intermittent fast which was kind of working.  This was before I started to do the green smoothies.  Well today I have just had a brainwave.  How about doing one day green smoothie diet, then the next fasting.  Just going to give it a try and see what happens.  I think I will have my smoothies on exercise days.  I will have a couple of days off, but not go to mad I hope.  So that works out at two days fasting, three day green smoothie diet, then two day semi green and fasting and what ever else happens.  I go out on a Thursday for lunch so this will be one of my days off.  And Saturday is always a bad day for me, especially if we go out.  I have posted a photo of one of my smoothies.  I do like to make them around 400 calories each because they are a meal.  I also like to make sure they have protein and fat in them.
