The science behind Biokode
How we compute your targets, score every meal, and where all of it comes from. No black boxes: formulas, ranges, and public references.
Health Index
Every meal you log gets a Health Index from 1 to 10 that sums up its nutritional quality at a glance. It's not an opinion: it weighs composition, nutrient density, and excesses following WHO dietary guidelines and reference authorities.
What it takes into account
Plate composition
Whole foods vs ultra-processed, and the real balance of protein, fat, and carbs in that meal.
Nutrient density
The fiber, vitamins, and minerals it provides — not just calories.
Penalized excesses
Added sugar, salt, and saturated fat above recommended limits cost points.
Verified coherence
The score is checked against the meal's mass and ingredients before it's saved, so it stays consistent.
Why our recommendations go further
Most apps calculate once with a fixed formula. Biokode combines deterministic math with adaptation to your real data.
Protein in g/kg, not a percentage
We set your protein in grams per kilo of body weight (1.4–2.2 g/kg by goal, sex, and age), not as a share of calories. So it doesn't collapse right in a deficit, when you need it most.
Adaptive TDEE from your data
Every week we recompute your real energy expenditure from your logged weigh-ins and intake, not a static formula. If your weight drifts, the plan rebaselines automatically.
Micronutrients against EFSA
We track 27 micronutrients and show your coverage as % of EFSA reference values, with correct units and without fabricating the ones a food doesn't report.
Food data with provenance
Our catalog is seeded from USDA and CIQUAL, with per-ingredient traceability. Calories are derived from macros (4/4/9 kcal + 7 for alcohol), not a loose number.
Integrated blood analysis
Upload a PDF of your bloodwork and the coach prioritizes food-first suggestions based on markers flagged by the lab itself — never re-diagnosing.
The number comes from the formula
A deterministic engine computes your targets; the AI only communicates them and never invents figures. You confirm before anything changes.
Clinical safeguards
Calorie floors, protections for minors and underweight, and eating-disorder guardrails. It is not a medical device and does not diagnose.
Scientific sources
Our recommendations draw on publicly available information from these authorities and studies. Biokode is not affiliated with or endorsed by them.
