Not literally, not for everything, that could get quite messy! Look at your hands when making your plate of food. Your palm is about the right size for a serving of protein. Make a fist, then make another one, that is about the right size for your servings of fruits and vegetables. Make a fist again, that’s about the right size for your serving of grains. A serving of nuts will fit comfortably in the palm of your hand. Your thumb will tell you the right size of healthy fat. Use your hands for your food, as your hands fit your body. Enjoy!
