Dr. Wei Zhang, MD

About Dr.

Dr. Wei Zhang is a physician based in Hong Kong focused on metabolic and weight-management medicine. He provides independent medical review of any content on The Calorie Tracker Guide that touches health outcomes, weight, or metabolic claims.

Wei checks that our coverage of GLP-1 medications, energy balance, and body-composition change is medically sound and appropriately cautious. He does not score apps; his role is to ensure nothing we publish overstates a health benefit or misrepresents the evidence.

Articles he has medically reviewed carry a dated review line so readers know a clinician has checked them.
