Professional Bio

Lily Nichols is a Registered Dietitian/Nutritionist, Certified Diabetes Educator, researcher, and author with a passion for evidence-based nutrition. Drawing from the current scientific literature and the wisdom of traditional cultures, her work is known for being research-focused, thorough, and sensible. Lily’s clinical expertise and extensive background in prenatal nutrition have made her a highly sought after consultant and speaker in the field.

Her work in the field of gestational diabetes, which presents a revolutionary nutrient-dense, lower carb approach, has not only helped tens of thousands of women manage their gestational diabetes (most without the need for blood sugar-lowering medication), but has also influenced nutrition policies internationally.  You can learn more about her approach in her bestselling book, Real Food for Gestational Diabetes (and online course of the same name).

Lily is also the author of Real Food for Pregnancy, which provides an evidence-based look at the gap between conventional prenatal nutrition guidelines and what’s optimal for mother and baby. With over 930 citations, this is the most comprehensive text on prenatal nutrition to date. Since its publication, it remains the #1 bestselling book on prenatal nutrition.

Lily’s third book, Real Food for Fertility (co-authored with Lisa Hendrickson-Jack), is a comprehensive resource on optimizing preconception nutrition — for both partners — to improve outcomes in fertility, pregnancy, and beyond. 

In addition to her books, Lily is founder of the Institute for Prenatal Nutrition®, where she mentors other practitioners on perinatal nutrition, and is the co-founder of Women’s Health Nutrition Academy, which offers individual webinars on a variety of women’s health topics.
