About

Physician, researcher, and science communicator.

Igor Carvalho de Oliveira, MD, MPH, known as Dr. Igor Deoli, is a board-certified General Preventive Medicine and Public Health physician with a Master of Public Health, both earned at the University of Rochester. His focus spans preventive cardiology, nutrition, metabolic and brain health, weight management, and athletic performance — including the hormonal side of training, drawing on his background as a former NASM-certified personal trainer. His work sits where the peer-reviewed literature meets the choices people actually make day to day.

Across unPRESCRIBED — his newsletter — along with YouTube, social media, and the writing here, Igor translates high-quality research into plain, usable guidance with a bit of entertainment. No hype: just the strongest evidence he can find and an honest read on what it means for you.
