Protein, carbs and fat: macros without the fuss
Macros are the three big types of nutrient that provide energy: protein, carbs and fat. Each has its role in the body, and what matters most isn't chasing the perfect ratio, but building a balanced plate with real food.
What each macro does
Macro is short for macronutrient: the nutrients your body needs in larger amounts and that provide energy. Protein helps build and repair muscle, skin and other parts of the body, and tends to be more filling. Carbs are the most direct source of energy, everyday fuel, and come from rice and bread as much as from fruit and vegetables. Fats, despite their bad reputation, are essential: they help absorb vitamins, produce hormones, and are filling too.
- Protein: builds and repairs; filling (egg, beans, meat, chicken)
- Carbs: everyday energy (rice, potato, fruit, oats)
- Fat: vitamins and hormones (olive oil, nuts, avocado)
Quality before ratio
It's easy to get lost trying to nail the exact split between the three macros, but that perfect math matters less than it seems. Two plates with identical macro numbers can be very different: rice and beans with salad isn't the same as a fried snack, even if the macros match. Food quality — how natural, colorful and varied it is — usually weighs more than the percentage on a chart. Instead of aiming for perfect numbers, it's worth building meals with a good protein source, real carbs and good fats.
Balance on the everyday plate
A simple way to think about balance is to look at the plate, not the calculator. Many Brazilian plates are already balanced: rice and beans combine carbs and plant protein, and you just add a protein, some vegetables and a drizzle of olive oil. There's no macro split that fits everyone — the right amount changes with the person, the goal and the routine, and that's a conversation for a nutritionist. What you can do on your own is aim for variety and the presence of all three macros in most meals, without turning every plate into a math test.
- Rice and beans already combine carbs and plant protein
- Add a protein, colorful vegetables and a good fat
- The ideal ratio is individual — align it with a nutritionist

See your macros approximately
When you log a meal in Nuya, including by photo, you see an approximate estimate of protein, carbs and fat — without becoming a slave to the numbers. Over time, you can spot patterns and chat with the AI in plain language. Remember the values are approximate and serve as a reference, not a fixed target: the ideal ratio for you is a matter for a nutritionist.
