Portion Size Estimates

Here’s a fast and simple way to know if you’re really eating a single portion.


  • What it is: As the body’s main fuel source, carbohydrates help build energy for the brain and muscles. Carbs  include whole grain breads, pastas, brown rice, couscous, quinoa and potatoes.
  • Portion Size:  A fistful is equal to one serving of carbs (this will increase if you’re training intensely).


  • What it is: Protein helps build muscle and maintain the immune system. Protein  sources include fish, chicken, turkey and beef.
  • Portion Size:  A palm full is an appropriate portion (this may slightly change with activity level—Goal: 0.8 – 1 gram per pound of body weight per day)


  • What it is: Healthy fats repair cells, help transport and absorb fat-soluble vitamins (A,D,E, and K), and help regulate blood sugar.
    Healthy fats  include olive oil, avocado and nuts.
  • Portion Size: Add in small amounts at each meal and snack (examples: 8 almonds, 1 teaspoon of olive oil, 1 tablespoon of peanut butter, 1/4 avocado are all equal to a single serving)
