Calories tell you a meal's total energy. But where that energy comes from matters too. That's where "macronutrients" — macros for short — come in. There are three of them, and each has its own job.
Protein — repair and fullness
Protein is the building block of muscle and tissue, and it's also the most filling macro. It helps preserve muscle when you're losing weight and build it when you're gaining. Meat, chicken, fish, eggs, legumes, and dairy are good sources. You can figure out your daily needs with the protein calculator.
Carbohydrates — your primary fuel
Carbs are the fastest source of energy for your body and brain. The "carbs are the enemy" cliché is misleading; the difference is in the source. Whole grains, bulgur, legumes, and vegetables also bring fiber, while refined sugar gives you a quick spike followed by a fast drop.
Fat — hormones and absorption
Fat carries the most calories per gram (about 9 kcal/g), so portions are easy to overlook. But it's essential for hormone production and the absorption of certain vitamins. Olive oil, nuts, avocado, and fish are quality sources. The point isn't to cut fat out, but to know how much you're eating.
How do you find the balance?
There's no single "right" ratio; it depends on your goal. To get started, the macro calculator splits your calories across the three macros in a reasonable way. After that, it's practice: photographing your plate to see its macro breakdown helps you notice, over time, which meals tend to come up short on protein.
