Why are habits so hard to build — and even harder to break? And do they really have to be perfect to improve your health? On this episode of On Nutrition, Mayo Clinic dietitian Tara Schmidt sits down with health coach Jenn Trepeck to explore the science of habits and how small, realistic changes can lead to lasting results. From decision fatigue to mindset shifts, they break down why so many health goals stall — and what actually helps them stick. They also discuss the role of health coaching, how habits evolve over time, and why flexibility — not perfection — may be the key to long-term success. Whether you’re trying to eat better, move more or reset your routine, this episode offers practical strategies to help you build habits that work in real life. ⁠Sign up⁠ to receive Mayo Clinic Press emails.  Find us online at ⁠Mayo Clinic Press⁠ for more health and wellness articles, podcasts and books.   Do you have feedback, questions or topic suggestions?
