Meet your dietitian
The dietitian behind Radiant — and the family that keeps her grounded.
Janna Weaver, RDN, LD, founded Radiant Nutrition after more than 20 years of helping people stop chasing perfect eating and start building habits that actually last. She knows how confusing nutrition advice can feel, because she has spent two decades guiding real people through it.
At home, Janna is a mom of two, and family life shapes how she practices: plans built for real schedules, real kitchens, and real birthdays — never judgment, never one size fits all. Her advanced certifications in adult and pediatric weight management and recognition as a DFW Mom-Approved provider reflect the same thing her clients say best: she listens first, then builds a plan you can live with.
- Advanced certifications in Adult and Pediatric Weight Management through the Academy of Nutrition & Dietetics
