Background

Hi there! I’m Katie Lightfield, a registered dietitian with a Bachelor’s in Nutrition and Food Science and a Master’s in Human Nutrition. I have years of experience in medical weight loss, weight management, GLP-1 therapy, emotional eating, and bariatric nutrition, including pre- and post-op care. I’m also well-versed in managing conditions like diabetes, insulin resistance, and heart disease.

Nutrition plays a key role in not just achieving a healthy weight and managing chronic diseases but also improving career success, emotional health, academic performance, and relationships.

Outside of work, I enjoy DIY projects with my husband, playing with our two young kids, and indulging in documentaries and mystery podcasts. On sunny days, I’m outdoors soaking up the sunshine.

I’m excited to help you on your path to a healthier, more balanced life!

Approach

"You are one of a kind, so your journey to better health should be unique too. I’m a great listener, allowing me to create personalized nutrition plans with achievable goals that foster lasting habits. Deprivation isn't the answer; I’ll show you how small, satisfying changes can help you feel in control. The path won’t always be easy, but setbacks are part of the process. I’m committed to supporting you for the long haul, adjusting the plan as life changes to keep you on track."
