The recipe

  • 1 cup milk244 g
  • 1 scoop whey32 g
  • ½ banana59 g
  • 1 tbsp peanut butter16 g
  • 1 tbsp cocoa5 g
  • 1 tbsp flax7 g
  • 2 cups spinach60 g
  • ½ cup water and ice120 g

Liquid first, then the protein, the frozen fruit, the seeds or oats and the greens. Blend about a minute.

Why it works

Cocoa and flax bring 4 g of fiber in two spoons, the half banana is all the sweet it needs, and two cups of spinach add 14 calories and the minerals a chocolate shake is missing.

One full scoop covers the meal line up to about 230 lb. The protein shake calculator trims the powder for anyone lighter.

The swap

No powder: 7 oz of Greek yogurt in place of the scoop. It grades A+, with 37 g of protein in 452 calories.

The priced parts come to $0.34. Whey, peanut butter, cocoa, flax and spinach have no federal price, so the takeout calculator asks for yours.
