How the numbers work
Step 01

Mifflin–St Jeor

We calculate your BMR (the energy your body burns at rest) using the Mifflin–St Jeor equation, the most accurate standard for everyday use.

Step 02

Activity & goal

Your BMR is multiplied by an activity factor to find maintenance, then adjusted for your goal: a 20% deficit to lose fat or a 10% surplus to build.

Step 03

Protein first

Protein is set to roughly 1g per pound of bodyweight to protect muscle, fat fills 25% of calories, and carbs take the rest to fuel training.

These figures are a generic, formula-based starting point, not medical advice, and not a plan built for you. Your real numbers depend on your history, hormones, training, stress, and how your body actually responds. That's the holistic picture I work through with you in coaching.

Numbers are easy.
Follow-through is the work.
