Lifestyle medicine is a nascent specialty that holds great promise in transforming the priorities of healthcare to achieve superior outcomes, primarily through the prevention/mitigation of chronic disease among diverse populations and environments. As this field emerges, many budding interests and theories will blossom into significant and relevant aspects of a more complicated enterprise. To better make sense of these moving parts, evolving at different paces and trajectories, and interacting in ways that are known and unknown, it becomes necessary to take inventory of relevant assets. This is the context of defining a lifestyle medicine eco-system, which guides the formation and optimization of a pragmatic infrastructure for research, education, and clinical practice. The tables in this chapter contain many items that can be used as starting points for lifestyle medicine practices as they initialize and develop. It is inevitable that lifestyle medicine will give rise to further specialization and a more complex eco-system, but hopefully, the infrastructure retains sufficient simplicity and practicality.
