🍳 Macro Calculator
Macros — protein, carbohydrate, and fat — are where your calories come from. Set your daily calories and goal, and this splits them into grams per day, with protein anchored to your body weight.

Protein: 2.2 g/kg of body weight
How the split works
Protein and fat are set first because they have floors you should not go below — protein around 1.6–2.2 g/kg to protect muscle in a deficit, fat around 0.6–1 g/kg for hormones. Carbohydrates fill the remaining calories and fuel your training. Protein and carbs are 4 kcal/g; fat is 9 kcal/g.
