Guides for protein, macros and calorie planning
Use these guide pages to understand what the PrimeMacros calculator estimates, where the model is useful and where a personal review matters more than any formula.
How PrimeMacros works
Energy needs are estimated from the Mifflin-St Jeor equation and your selected activity level.
Protein targets are based on body weight, selected planning range and optional adjusted-weight logic for higher BMI values.
Macro targets are planning estimates, not a diagnosis or an individualized nutrition prescription.
Use the calculator carefully if
you are pregnant, breastfeeding or under 18 years old
you have diabetes, kidney disease, eating-disorder symptoms or another condition that affects nutrition planning
your training, medication or health situation changes faster than formulas can reflect
