A structured transformation program based on metabolic and lifestyle optimization.
My approach
I don’t believe in restrictive diets or short-term solutions.
Instead, I help people build sustainable habits that improve metabolic health while still enjoying food and lifestyle balance.
This approach is reflected across all Dietisha content in:
Working across different countries has shaped my approach to nutrition:
health is not universal, it must be adapted to culture, environment, and lifestyle
Global perspective
Originally trained in Mexico City, I later expanded my work internationally, practicing and developing epigenetics-informed nutrition strategies in Spain while continuing to support clients there.
After living in Toronto and working across diverse health and cultural environments, I am now based in New York, working with clients internationally through Dietisha.
