What Is Personalized Nutrition?

Nearly every piece of nutrition advice you've ever read was written for a person who doesn't exist: the 2,000-calorie average adult on the back of every food package. Personalized nutrition is the correction — the practice of setting food targets from your age, sex, size, activity, life stage and health context instead of a national average. The idea is simple. The arithmetic is not, and that's the actual barrier.

Why the average fails almost everyone

Energy needs alone span an enormous range — a small, sedentary older adult may need under 1,600 calories a day while an active teenager needs over 3,000. Nutrient needs diverge just as sharply: iron requirements nearly double for menstruating adults, calcium needs peak in adolescence, protein needs rise again in older age to protect muscle. Feeding everyone the same target overfeeds some household members and shortchanges others — usually at the same dinner table.

What it takes to do it properly

A dietitian personalizing your nutrition would estimate your basal metabolic rate, scale it by activity into daily energy expenditure, then look up your age-and-sex-specific targets across dozens of nutrients in the Dietary Reference Intakes — the National Academies' standards behind U.S. nutrition policy. Then they'd translate those numbers into actual food. Now repeat that for every person in the household, and again whenever a child crosses an age bracket. It's expert work, it's tedious, and it's why almost nobody does it manually.

How Aevicor automates the calculation

This is precisely the problem our Digital Health Assistant was built to remove. The complimentary assessment computes your BMI, BMR and daily energy expenditure from a few questions — the body-metric models run in your own browser — then matches your profile against DRI-derived targets by age and sex to produce your personal nutrient needs, each explained in plain language. The full pipeline, including data sources and limits, is documented in how our analysis works.

From one profile to a household

The harder version of the problem is the family: a toddler, a teenager and a grandparent should not eat the same way, yet they share one cart and one budget. Aevicor's marketplace is built around household profiles — each member's needs computed individually, then aggregated into a single shopping plan. When buyer enrollment opens in November 2026, those aggregated needs become ready-to-buy carts from local producers: the full loop from “what do we each need” to “what do we buy.”

What personalized nutrition is not

Honest personalization stays inside the evidence. Our targets come from established reference intakes — not blood tests we haven't run, genetic claims we can't support or diagnoses no app should make. Estimates like BMR are population models with real error bars, and nothing here replaces a clinician. Treat personalized targets as a vastly better default than the 2,000-calorie average — not as medicine.
