Thirteen's Macro Calculator

What is a Macro Calculator?

​

A macro calculator estimates how many calories your body needs each day and breaks that total down into protein, carbohydrates and fats... your “macros”.

​

It uses your personal stats and goal (fat loss, muscle gain or maintenance) to calculate:

• Your estimated daily calorie target
• How much protein to support muscle retention and recovery
• How many carbs to fuel training and performance
• How much fat to support hormones and overall health

 

At Thirteen, we don’t rely on guesswork or extreme dieting. We use numbers as a starting point, then adjust based on real progress.
