Are you feeling stuck in a cycle of dieting, struggling with your relationship with food, or unsure how to support your child’s eating? I can help.
I’m Marissa Beck, a non-diet dietitian specializing in eating disorders, weight concerns, and sports nutrition. With over 15 years of experience, I help people heal their relationship with food, eat in a way that feels better, and improve their overall well-being, without restrictive diets.
Whether you’re navigating binge or emotional eating, or concerns about weight, or seeking support for your child, I provide practical, evidence-based guidance. My approach is compassionate, judgment-free, and rooted in science, so you can feel more at peace with food and your body.
It’s possible to find a way of eating that feels easier, more satisfying, and less stressful. You deserve support that meets you where you are without guilt, shame, or judgment. I’d love to help you take that next step.
