While this may have some potential positive benefits like decreasing healthcare costs and nudging you to eat better foods, exercise more and use cheap preventive health care services - it is rife with diagnostic accuracy problems at this time considering the high rate of false positives, bad data, patterns that mean nothing, correlations that do not equal causation, and discounting genetic and other factors. Human physiology is a high causal density environment and assessing overall health is tricky even for trained physicians.
