As a leader, you make dozens of decisions every day, but the ones you make about your own body often get pushed to the bottom of the list. The truth is, how you eat directly shapes your energy, mood, focus, and ability to lead well.

Gayle Lantz speaks with Dr. Sina Smith, a physician trained in biomedical medicine who later became a licensed acupuncturist, expanding the ways she helps patients think about health. She combines both perspectives in her Chicago practice, along with years of teaching, speaking, and writing. She is also author of Demystifying Acupuncture: Modern Answers About Ancient Medicine.

In this first part of a two-part conversation, Dr. Smith shares practical, no-nonsense strategies for eating well on the go without needing to become a gourmet cook or overhaul your entire lifestyle. From smart grocery shopping to handling travel and stress-eating, she offers simple shifts that busy leaders can start using right away.
