Quotes from Dr. D'Adamo About Type O Nutrition, Health and Stress

If you are new to the Blood Type O Diet, returning to it, or have been living this way for years, we can all benefit from revisiting the original work of Dr. Peter J. D'Adamo.

Believe it or not, much of what circulates on the internet today is fragmented, simplified, or pulled out of context.  Many people are running with misunderstandings and inaccurate food lists.  That’s not helpful when striving to build a nutritional foundation.

That’s why I created this page, as a place to slow down and reconnect with the source, the original words.  The quotes shared here are drawn from several of Dr. D’Adamo’s books, including Eat Right 4 Your Type and Live Right 4 Your Type, which will be noted next to each quote.  

I have curated them here as reminders and guide posts.  As reference points to return to when you’re starting out, after you’ve reached a milestone and as confirmation to course correct or keep going.  As you read them, notice what lands and let understanding build over time.  

This will be here as you move along your journey.

These quotes are not meant to be memorized or followed perfectly. They are meant to be returned to.

For many Type O women, clarity doesn’t come from more information, but from reconnecting with the biological truths that have been there all along. When read slowly and in context, these words offer reassurance, orientation, and a deeper understanding of why certain foods, rhythms, and practices either support or strain the body.

You may find that different passages stand out at different times. Let that be part of the process. Revisit this page when you feel uncertain, overwhelmed by conflicting advice, or simply in need of grounding.

If you’re ready for a quieter, more embodied way to explore this work, you’re welcome to enter the Room for Sacred Softness. It’s a free space created for Type O women to slow down, listen to their bodies, and begin integrating nourishment and nervous system support at a gentle, sustainable pace.

Take your time and listen to your inner guidance.
