Meat and other protein foods don't contain significant amounts of carbohydrate. But you still need to know the standard portions for these foods.

Meat, poultry, fish, eggs, cheese, and nuts:

• 2 to 3 oz of cooked lean meat, poultry, or fish (3 oz is about the size and thickness of a deck of cards)
• Count the following as equal to 1 oz of meat:
  • ¼ cup cooked dry beans
  • 1 egg
  • 2 Tbsp peanut butter
  • 1 oz cheese
  • ¼ cup cottage cheese
