Marilyn Luis

I'm Marilyn Luis — a degree-trained nutrition specialist with a deep understanding of biochemistry and a dedicated focus on women's health, metabolism, and anti-aging in midlife.

I created Estrogen Left the Chat because I saw how many women were being given symptoms without context. They were told they were tired, gaining weight, sleeping badly, feeling foggy, inflamed, or unlike themselves — but rarely given a clear, intelligent explanation of the physiological changes happening underneath it all.

My work brings together nutrition, metabolism, hormonal health, and biochemistry-informed strategy to help women understand what changes in midlife actually mean. I'm particularly focused on the relationship between hormones, stress physiology, body composition, energy, cognition, appetite, and long-term vitality.

I believe women deserve better than generic advice and empty wellness trends. They deserve practical, science-aware guidance that helps them work with their changing bodies — not against them.

The Mission

At the heart of my work is a simple idea: when women understand the biology of what they're experiencing, they can make better decisions, support their bodies more effectively, and move through this phase with greater strength and confidence.
