A macrobiotic lifestyle (Gr. for "big life," or "long life") can be defined as "the art of living while being conscious of the polar principles that govern the universe." This is in reference to the ancient Chinese concept that the world can be understood in terms of the two antagonistic, yet complimentary, forces, Yin and Yang.

People who choose the macrobiotic lifestyle generally strive to observe these forces in their everyday lives and use this as a key for obtaining balance, harmony and happiness, both physically and mentally. This lifestyle entails careful selection and preparation of food, and attention to one's physical activity and social contact.
