Owner and Registered Dietitian
Lauren Chaffin, MS, RD, LD
Born, raised, and located in Houston, Lauren Chaffin, owner of Nourished Nutrition Therapy, is a Master's level registered and licensed dietitian who works in weight inclusive nutrition therapy and eating disorders. A second-generation Aggie (whoop!), she received her Bachelor of Science in dietetics from Texas A&M University, then went on to complete a distance dietetic internship from the University of Delaware. Her Master of Science was completed through Logan University.
After receiving a diverse and well-rounded experience in clinical, outpatient, PHP, and residential settings, she decided it was time to venture out and start her own practice to focus on her passion- to help others have a positive relationship to food and their body in order to live the life they were meant to without the baggage of our culture. She is committed to forming relationships with clients looking to heal their relationship with food and body, those with eating disorders and disordered eating, those looking to manage their diagnosis with nutrition science, and much more. Nourished Nutrition Therapy is here to provide accessible outpatient nutrition care.
Her greatest hope is for people to be able to use nutrition knowledge as a self-care tool in order to improve their life and well-being.
Lauren is in network with BCBS, UHC, Cigna, Community Health Choice, and Sana.

Registered Dietitian
Sierra Bell, MS, RD, LD
Sierra Bell earned her bachelor’s degree in nutrition from Sam Houston State University (Eat ’em up, Kats!) and her master’s degree in nutrition from Texas Woman’s University in Houston. During her graduate studies, she fell in love with nutrition education and helping people find balance with food in a way that feels good for the long run.
Sierra is all about empowering you to feel confident in yourself and the habits you build—whether that means repairing your relationship with food, learning to listen to your body, or creating daily routines that support your overall well-being. She blends intuitive eating principles with gentle, practical strategies so you can create changes that last without feeling restrictive or overwhelming.
Her approach is rooted in connection—meeting you where you are, helping you stay accountable, and keeping the process enjoyable (yes, a little fun is always included). Sierra’s goal is for you to feel supported, understood, and excited about taking care of yourself for life.
Sierra is in network with Aetna, BCBS, and UHC.

NOURISHED NUTRITION THERAPY
Find Food Freedom
Our primary goal is to help you break free from diet culture. To give you a life beyond dieting and be able to feel confident in your own skin. To find food freedom without any shame or guilt weighing you down.

OUR PHILOSOPHY
Weight Inclusive Nutrition Care For All
Food should not be something that is feared or moralized. All foods fit, in any amount, at any time. Bodies should be respected and appreciated just as they were designed, not judged and criticized for worldly imperfections. Weight is not an indicator of health, and in fact, weight cycling and weight stigma cause damage. Self-care and self-compassion are essential to good health. Mental health is a crucial part of overall health and well-being.
