Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

METABOLIC INTEGRATION + NUTRITION

YEAR 1 | PAGE 10B - GLYCOGEN + PPP + LIPIDS + AMINO ACIDS + NUTRITION

2026 USMLE NUTRITION EMPHASIS

USMLE now lists Nutrition at 15-20% discipline overlap on Step 1 and enhanced nutrition science across all Step exams beginning June 2026. Study vitamins, macro/micronutrients, fed/fasted physiology, malnutrition and metabolic disease as integrated clinical science.

  • Track carbon and reducing equivalents across carbohydrate, lipid and amino-acid metabolism in fed, fasting and prolonged fasting states.
  • Know vitamin/cofactor roles by reaction type and predict the metabolic/neurologic/hematologic consequence of deficiency.
  • Connect glycogen, FA-oxidation, urea-cycle and lysosomal disorders to the blocked reaction, accumulated substrate and deficient product.
  • Interpret nutrition-related clues: starvation/refeeding, alcohol, malabsorption, bariatric surgery, restrictive diets and micronutrient deficiency. VIDEO-FIRST | SCHOOL-EXAM + BOARD-EXAM MASTERY
