Dr. Maya Ostrowski

Who is Dr. Maya Ostrowski?

Maya leads the nutrition research desk at Fitness Tracking Guide. She designed the 16-week, 127-reviewer adherence cohort that anchors our nutrition and weight-loss rankings, and she personally weighs every reference meal that goes into our 360-meal blind-test set for AI photo-logging accuracy. Before joining the publication, Maya spent eight years as a clinical dietitian in academic medical centers, where she ran the outpatient bariatric and GLP-1 transition programs — work that still shapes how she scores apps on long-horizon adherence rather than week-one excitement.

Her bench against MARS (Mobile App Rating Scale) and COSMIN measurement-property frameworks is what makes our v3.1 methodology defensible. Maya is the lead author on every nutrition, weight-loss and calorie-tracking review on the site, and the second reviewer on every cycle, fasting and hydration piece.

Outside of testing apps, Maya is an unreliable but enthusiastic sourdough baker and runs a small Boston-area book club for clinical dietitians.
