A healthier, more sustainable relationship with food
I'm Dr. Ana Gaby Castro. I help people understand why they eat the way they do — and build, from medicine and evidence, their own path to well-being.
Three pillars, one lens
I work at the intersection of medicine, behaviour and emotion. Every plan combines these three approaches, without dogma and without magic shortcuts.
Psychonutrition
A reading of eating behaviour from the emotional, cognitive and cultural context.
Cognitive Behavioral Therapy
Practical strategies to identify and transform automatic thoughts about food and body.
How I work
My approach is compassionate, slow when needed, firm when needed. No restrictions. No guilt. Just science.
01
We listen
An opening session to understand your medical, emotional and food story — with no rush and no prescriptions.
02
We read together
We map patterns, triggers and strengths. You leave with a clear picture of what we observe.
03
We build
A realistic plan, step by step, with goals you can actually carry into your everyday life.
04
We support
Close follow-up, fine-tuned adjustments and practical tools between sessions.
