The Guest Series, Ep 2: Fitness from the Inside Out with Celeste Harrington (Body Recomposition, Healthy Mindset, and Realistic Goals)
EPISODE #63 — OCT 24, 2025
This week, we’re continuing “The Guest Series” — a curated collection of the most loved and listened-to interviews on the podcast. In this 5-part conversation series, you’ll hear from trusted voices in women’s health on topics like menstrual cycles, hormone balance, body image, relationships, nervous system healing, and integrative medicine.
In this episode, we’re joined by Celeste Harrington, a fitness coach and global well-being program manager for some of the largest tech companies in the world. We discuss mind-body health and address the connection between body image, societal norms, and the stigma around wanting to look a certain way. She emphasizes the importance of setting realistic fitness expectations and shares practical strategies for body recomposition (including how eating more can often actually lead to weight loss). We talk about the role of hormones, the importance of protein intake, and putting together a fitness plan that allows for both motivation and flexibility.
