The Maths Behind the Calculation

TDEE + Goal Adjustment

First, TDEE is calculated (Mifflin-St Jeor). Then, calories are adjusted for your goal (e.g., -20% for fat loss). Finally, macros are split (e.g., 30% Protein / 35% Fat / 35% Carb).

Knowledge Base

Frequently Asked Questions

Which macro split is best?

There is no single best split. 30/35/35 is a balanced starting point. Athletes may need more carbs, while ketogenic dieters need more fat.

Do I need to hit numbers exactly?

Consistency is key, but exact precision isn't necessary. Aim to be within +/- 5-10 grams of your targets.
