Precision Nutrition with Fanny is a personalized, integrative approach to wellness led by Fanny Rengasamy Marianne, a certified nutritionist in Mauritius, Precision Nutrition Coach, and Bioresonance Therapist. My work exists for one purpose: to help women build a body — and a nervous system — that finally feels safe. Because when the body feels safe, healing becomes possible.

I serve women who feel depleted, overwhelmed, or disconnected from their bodies — often despite doing everything right. Fatigue. Digestive discomfort. Hormonal imbalance. Brain fog. Emotional strain. Symptoms that haven’t found lasting answers anywhere else.

My question is never “what is wrong with you.” It is: what is your body trying to protect you from?

Through Precision Nutrition, I tailor macronutrients to support metabolism and body composition, while restoring the micronutrients — vitamins, minerals, antioxidants — that shape mood, cognition, hormones and vitality. Micronutrients define how you feel. Macronutrients define how you look.

Through Bioresonance Therapy, I assess and regulate the body’s energetic patterns to explore root causes — stress, toxins, digestive strain, emotional imprints — and support detox pathways, organ function, nervous system regulation, and the body’s own capacity to heal.

Together, these two disciplines don’t fight disease. They partner with your body, restoring the internal conditions where energy, clarity, hormonal balance and trust in your own intelligence can return.

Health is not luck. It is coherence. If you’re ready to understand what your body has been trying to tell you, book an appointment today and begin restoring that safety — one aligned step at a time.
