About
Marcelo Guedes, RD is a sports and functional clinical nutritionist at Instituto Assaly. He trained in nutrition at UERJ, then added postgraduate work in public-health nutritional interventions at UFRJ, functional clinical nutrition at UNICSUL, and orthomolecular nutrition applied to nutrigenomics at FAPES. His clinical base includes coordinating hospital and outpatient nutrition for the Brazilian Air Force, and he has worked in clinical, sports, and high-performance nutrition since 1999.
What to Know
Signature approach
Guedes builds plans from a data set: clinical history, anthropometry, lab profile, food-intolerance information, and a genetic panel. The goal is not just a sports diet; it is a routine the patient understands and can maintain. Functional and orthomolecular nutrition guide how he reads the labs, while the nutrigenomics training shapes how he uses the panel.
What sets them apart
- Long performance-nutrition arc. Sports, clinical, and high-performance nutrition work dates to 1999.
- Institutional clinical base. Brazilian Air Force hospital and ambulatory nutrition coordination gives his sports practice a more clinical foundation.
- Public-health to genetics range. UFRJ public-health nutrition at one end and FAPES nutrigenomics at the other create a broad planning lens.
