  • 1/2 cup strongly brewed green tea
  • 1/4 cup coconut milk canned, full fat
  • 2 cups spinach fresh or frozen
  • 1 banana green, peeled and frozen
  • 1 grapefruit peeled, frozen
  • 1 cup pineapple chopped, frozen
  • 4-5 pieces of ice
  • 10 grams whey protein isolate


  • Add all ingredients to a blender, starting with liquids and greens, and adding frozen fruit, ice, and protein powder to the top.
  • Blend until ultra creamy. Add extra green tea or water if you like a thinner smoothie.
  • This recipe makes 2 smoothies, because I have found it is easier to blend 2 portions rather than just one in my blender. If you don't have someone to share it with, freeze half and drink it the next day. I find the texture is still great if I let it sit out for about an hour before I drink it, and stir well.



If using a protein powder in this recipe, be sure to buy one that is sugar free and also free of chemical sweeteners. The one I recommend is Whey Protein Isolate, which means it's just protein, no carbohydrates or fats. It's also from a grass-fed source, making it a higher nutrient source. Protein powders are not always great for you! Be picky.
Green bananas are simply unripe bananas. If you've never used green bananas before and are used to sweeter drinks start by freezing your bananas when there is just a little green left on them, and then gradually start buying them more green and freezing them earlier. Bananas are high in resistant starch before they fully ripen, which is a beneficial fiber that our bodies don't fully break down, making them lower in sugar and calories and better for gut health.
I often make 2 of these smoothies (the recipe is for 2 servings), and freeze 1. The next day I let it sit out for 30 minutes to an hour, give it a stir, and drink it while it's still partially slushy.
