What makes a smoothie low in calories but high in protein?

Start with protein, add fiber and keep added sugar low. A dietitian quoted in a weight-loss smoothie roundup recommends protein, fiber and healthy fats to help you feel full, limiting added sugar, and aiming for under 300 calories per serving. For a meal-replacement shake the article suggests 3 to 5 g of fiber, 10 to 20 g of carbohydrate and 15 to 30 g of protein. Use these as guides, not rules.

A simple formula

  1. Liquid: about 1 cup of unsweetened almond, soy or skim milk.
  2. Protein: Greek yogurt, kefir, cottage cheese or a scoop of protein powder.
  3. Fruit: a handful of frozen berries or half a banana.
  4. Fiber: spinach, chia seeds or oats.
  5. Ice: blend until smooth.

Amounts depend on your target, so check the labels of the yogurt and powder you use and add up the calories.
