Macro Calculation

Teaches macronutrient calculation frameworks including Total Daily Energy Expenditure estimation, macro ratio allocation by goal (fat loss, maintenance, muscle gain), and adjustment protocols.

Download Murage

Free and open source. macOS, Windows and Ubuntu.

Try it

Add the skill to a bot, then ask your Chief of Staff:

“Use the Macro Calculation skill on this: [describe the job, or paste your notes].”

The Mifflin-St Jeor equation is the most validated for non-athletic populations and outperforms the older Harris-Benedict equation in accuracy studies. The Katch-McArdle equation (BMR = 370 + 21.6 x lean body mass in kg) is superior when you know their body fat percentage -- use it when that data is available.

Skill Guard: clean

Scanned and clear. A bot can use it as soon as you add it.
