Our Methodology
How We Ensure Evidence-Based Accuracy
Food Data Sourcing
Our database contains 4,811 foods with 14 nutrients per food, including macronutrients, minerals, and vitamins. Every value is cross-referenced with USDA FoodData Central — the gold standard in food composition analysis.
Automated 6-level validation scripts check every entry for calorie anomalies, missing values, and macronutrient inconsistencies. Each food undergoes manual review before publication.
Research Curation
Calibr8 processes 2,000+ peer-reviewed studies through an automated pipeline that fetches publications from PubMed, Semantic Scholar, and OpenAlex. AI analysis evaluates the quality and relevance of each paper.
Scimago journal rankings further enhance quality scoring — publications from Q1 journals receive higher weighting. Final selection is always done manually by a qualified nutrition coach.
Adaptive Coaching
Macronutrient formulas are grounded in established sports science — Mifflin-St Jeor for basal metabolic rate, combined with individual activity and goal multipliers.
Every week the system recalculates macro targets based on real progress data — weight changes, plan adherence, and user feedback. This ensures continuous adaptation rather than static numbers.
