About

This site provides a free, browser-based calculator that helps you understand how much fiber and protein you need each day, based on published Dietary Reference Intake values from the Institute of Medicine (NIH).

The calculator is simple by design: no accounts, no tracking, no data stored. You enter your age, sex, and optionally your body weight and current intake — the numbers are calculated entirely in your browser and never leave your device.

The goal is to make population-level nutritional reference data accessible and easy to understand. Not medical advice, not a diet plan — just the numbers, clearly presented.
