About Maria Emmerich
Maria Emmerich is an internationally recognized nutritionist, bestselling author, and metabolic health expert specializing in ketogenic, carnivore, and protein-focused nutrition. For more than 25 years, she has helped people around the world lose weight, improve metabolic health, and reclaim their lives through evidence-based nutrition.
Maria’s passion for nutrition began with her own health struggles. As a teenager, she battled obesity, depression, low energy, and polycystic ovary syndrome (PCOS). Rather than accepting medications as her only option, she transformed her health through a nutrient-dense, low-carbohydrate lifestyle. That personal journey inspired her to pursue degrees in nutrition and exercise physiology and dedicate her career to helping others achieve lasting health.
Today, Maria works with clients worldwide through private consultations, group coaching, and educational programs. She is known for helping individuals address obesity, insulin resistance, type 1 and type 2 diabetes, autoimmune conditions, Hashimoto’s thyroiditis, epilepsy, neurological disorders, hormone imbalances, cardiovascular risk factors, anxiety, depression, and other chronic metabolic conditions using personalized nutrition strategies.
Maria is also an internationally bestselling author of more than 20 books, including The Art of Metabolic Health, Keto: The Complete Guide to Success on the Ketogenic Diet, Quick & Easy Ketogenic Cooking, The 30-Day Ketogenic Cleanse, and The Carnivore Cookbook. Her work has reached millions of readers worldwide and has been featured by celebrities including Halle Berry, Valerie Bertinelli, and Al Roker. Maria has collaborated with Halle Berry on ketogenic education and contributed recipes and nutrition content for Halle’s wellness platform, including receiving the foreword from Halle for Sugar-Free Kids.
Alongside her husband, Craig Emmerich, Maria has trained hundreds of health professionals through their Keto, Carnivore, and Protein-Sparing Modified Fast (PSMF) Health Coach Certification programs. Together they continue to educate coaches, healthcare professionals, and individuals on the science of metabolic health and therapeutic nutrition.
Maria’s mission is simple: to empower people with practical, science-based nutrition that addresses the root causes of chronic disease—not just the symptoms. She believes food has the power to transform lives, improve mental and physical health, and restore hope for those who have struggled to find answers.
When she isn’t writing, teaching, or coaching, Maria enjoys creating healthy recipes that prove nutritious food can be both delicious and sustainable. She believes that healthy eating is not a temporary diet but a lifelong lifestyle that allows people to feel their best while still enjoying great food. Maria and Craig adopted their son’s, Micah and Kai, from Ethiopia using proceeds from their first cookbook to help fund the adoption.
