1. AI assistance and authorship disclosure

IZEM may use generative AI to assist with drafting, organizing structured tables, checking code or markup, or translating text. Every public guide, calculator, and comparison page is governed by repository verification rules and accountable human publication. We do not assign a fictional human biography to an AI system, claim first-hand laboratory testing that did not occur, or publish invented interviews, clinical trials, user counts, credentials, or testimonials.

2. Calculator formulas and exercise-science methodology

Public calculators and planning hubs on youraicoach.life run directly in the browser using published equations from peer-reviewed nutrition and strength-conditioning literature. All outputs are educational starting estimates for healthy adults.
