Kristie Sullivan is passionate about helping others learn how to follow and sustain a low carb lifestyle. Her passion is fueled by her personal experience with obesity which started in childhood. Kristie began a strict ketogenic lifestyle in 2013. As a result, she has lost over 100 lbs and significantly improved her health.

Because of her personal success, she began helping others who also struggled as she did. Kristie established a popular YouTube channel, Cooking Keto with Kristie. She has also authored three best-selling books, Journey to Health: A Journey Worth Taking, Keto Living Day by Day, and Keto Gatherings. Kristie focuses on a clean-eating approach to a very low-carbohydrate diet.

At Diet Doctor, Kristie focuses on building community among members and supporting them as they adopt a low carb or keto lifestyle. Not only does she respond to member questions and comments, but she also administers a members-only Facebook group for Diet Doctor subscribers. Kristie believes that enjoying low carb foods is a significant factor in long-term success, so she also contributes seasonal recipes to the Diet Doctor website and has two seasons of cooking videos available for members.

Season two of Cooking Keto with Kristie features her in the kitchen with low carb leaders, researchers, and physicians, chatting about various topics and creating . Last, Kristie also contributes to help inspire or motivate those who might also struggle with obesity.

Kristie holds a Ph.D. in Educational Research and Policy Analysis from North Carolina State and enjoyed a 30-year career in higher education before joining Diet Doctor full time. She lives in the beautiful Sandhills region of North Carolina with her husband, David and their two children, Grace and Jonathan. David and Grace also follow a very low carb diet.
