Kinetics: USMLE Nutrition Prep

Kinetics is designed for medical students preparing for Step 1, Step 2 CK, and Step 3, built around the 2026 USMLE update that broadened nutrition biochemistry and chronic-disease testing across all three Step exams. Every case, pathway, and question is mapped to the JAMA 2024 nutrition-competency framework that the USMLE cites as its alignment standard.

WHO IT'S FOR
‣ Medical students preparing for USMLE Step 1, Step 2 CK, and Step 3
‣ M1/M2 students in biochemistry and nutrition courses
‣ International medical graduates (IMGs) preparing for US licensure
‣ Residents reviewing nutrition for in-training exams or board recertification
‣ PA, NP, and pharmacy students mastering nutrition mechanisms

THE FOUR-PILLAR LOOP
Every session follows the same flow:
‣ QUESTION - Practice with NBME-format vignettes. Pick from five lettered choices. Get a mechanism-deep rationale for every answer - correct and distractor - plus a takeaway summary and JAMA competency tags.
‣ CASE - Open a patient vignette. Review the history. Order relevant labs at a cost - targeted workups earn more. Commit to a differential diagnosis.
‣ PATHWAY - Once you nail the DDx, map the biochemistry. Drag substrate, enzyme, cofactor, and product into a mechanism chain that explains why the clinical picture emerged. Understanding builds as you build.
‣ SPACED REPETITION - Missed a pathway? It returns tomorrow. Nailed it? It advances to 3, 7, or 21 days. Your knowledge stays durable between now and test day. Every question links to a relevant pathway and case for drill-deeper learning - wrong answers become entry points to mechanism mastery, not dead ends.

CONTENT
‣ 260+ NBME-format USMLE-style questions across Step 1, Step 2 CK, and Step 3, with full per-distractor rationales and clinical takeaways
‣ 22 topic anchors: 13 vitamins, 6 minerals, and 3 macronutrient pathways - carbohydrate, fatty-acid, and amino-acid metabolism (urea-cycle nitrogen disposal)
‣ 100+ clinical cases covering deficiency, toxicity, and dysregulation
‣ 70+ mechanism-chain pathways, each with a clinical pearl
‣ Drug-induced deficiencies taught as causal chains: metformin and B12 in long-term diabetics, phenytoin and folate in seizure patients, TMP-SMX and folate on PCP prophylaxis, and more. Includes a searchable drug-nutrient interaction index for fast lookup.
‣ Macronutrient metabolism aligned
