The Math

How body recomposition works.

Three steps from your numbers to a calorie cycling plan that builds muscle and drops fat.

Step 01

Calculate your TDEE baseline

Mifflin-St Jeor BMR times your activity factor. This is how many calories your body burns on an average day — your maintenance level.

Step 02

Set up calorie cycling

Training days get a slight surplus to fuel muscle growth. Rest days get a deficit to burn fat. The weekly average stays near maintenance.

Step 03

Hit your protein floor

1g of protein per pound of bodyweight is the non-negotiable floor for recomp. Protein preserves muscle during the deficit and builds it during the surplus.
