Calories & Nutrition
Understand how many calories your body needs, how to set up a sustainable deficit or surplus, and how to split your macronutrients sensibly.
Calorie and macronutrient calculators give you a reasonable starting estimate based on validated equations like Mifflin-St Jeor. Real-world energy needs vary day to day, so use these numbers as a baseline, monitor how your body responds over a few weeks, and adjust gradually.
