Macros: protein, carbs and fat explained

Macros are the three nutrients that carry calories. Protein and carbs have 4 calories per gram, fat has 9. Counting macros is counting calories with more detail, and it matters most if you care about protein or train for strength.

Pick a split, hit it without weighing every lettuce leaf, and know when calories alone are enough. Every meal you log in Calsa shows protein, carbs and fat next to its calories.
