Have you ever caught yourself wondering why you eat the way you do? Maybe you’ve asked, “Why do I overeat?” “Why do I restrict?” or even, “Why do I bounce between the two?” And maybe you’ve started to realize—it’s not just about the food, or your body. So what is it really about? As a Nutrition Counselor, Registered Dietitian and Body Image Therapist, I get how layered and frustrating this can feel. I understand the guilt, the self-blame, and that overwhelming sense that food somehow has power over you. You’re not alone—and you’re not broken. You deserve to feel comfortable.

Are you a high-functioning woman 35+ whose digestion has gotten annoyingly unpredictable? Bloating shows up out of nowhere. IBS patterns shift. Hormonal changes make your “usual fixes” stop working. You’ve tried elimination diets and supplements that promised clarity and delivered... nothing. You want a structured, evidence-based plan to stabilize digestion, support hormone-related symptoms, and eat without constant second-guessing. I’ve lived with Crohn’s disease for more than three decades. That perspective informs a clinical approach focused on discernment and durable results, not generic advice or trend-driven protocols.
