Macro Calculator - UniversalNest

What it does

Most macro calculators online use rough shortcuts. This one runs on the Mifflin-St Jeor BMR equation and ISSN 2017 protein guidelines - the same methods used in real coaching and clinical settings. Enter your stats, pick a goal (fat loss, muscle gain, maintenance, recomp), and get your calorie target plus a protein/carb/fat breakdown with grams and percentages. Supports metric and imperial. No sign-up, no ads, no email gate.

Built on the Mifflin-St Jeor BMR equation and ISSN protein guidelines — the same five-step method used across labs and coaching programs, not a roughfrom universalnest.com
