Not a generic formula. Your calories and macro targets based on your actual body, activity level, and what you're trying to accomplish.
Macros โ short for macronutrients โ are the three main categories of nutrients your body uses for energy: protein, carbohydrates, and fat. Every food you eat is made up of some combination of these three. Tracking macros means paying attention to how many grams of each you eat per day, not just total calories.
Why does this matter? Because 1,800 calories of mostly sugar hits your body very differently than 1,800 calories with adequate protein and healthy fats. Macros give you a more complete picture of what you're fueling your body with.
Think of protein as the building block for muscle and satiety โ it keeps you full and helps your body repair. Carbs are your body's preferred energy source โ especially for exercise. Fat is essential for hormones, brain function, and absorbing certain vitamins. You need all three. Anyone telling you to cut out an entire macro group is selling something.
