The Math

How your macros are calculated.

Three steps from your numbers to grams on the plate.

Step 01

TDEE + goal modifier

Mifflin-St Jeor BMR x activity = TDEE. Cut: -20%. Maintain: 0. Lean bulk: +10%. That gives your daily calorie target.

Step 02

Protein floor

We respect a protein floor of 0.8-1.2g per lb of bodyweight (1.0-1.6g cutting) regardless of diet style - because under-eating protein wrecks results.

Step 03

Macro split

Remaining calories split by your chosen diet (balanced, high-protein, low-fat, low-carb, keto). Protein/carbs = 4 cal/g; fat = 9 cal/g.
