Macros

Short for macronutrients: protein, carbohydrates, and fats that make up the caloric content of food. Macronutrients are the three primary nutrients your body needs in large quantities: protein (4 calories/gram), carbohydrates (4 calories/gram), and fat (9 calories/gram). Tracking macros means monitoring the balance of these nutrients to align with specific fitness goals.

Understanding macros is fundamental to achieving any body composition goal, whether that's fat loss, muscle gain, or maintenance. Without this knowledge, you're essentially guessing with your diet.

You can track macros using Fitnit's AI nutrition scanning feature. Simply take a photo of your meal, and the app will analyze the nutritional content including calories and macro breakdown. For manual tracking, start by calculating your daily targets based on your goals and body stats.

Macros is closely connected to TDEE, Caloric Deficit, Caloric Surplus, BMR. Understanding these related concepts together gives you a more complete picture of nutrition science and helps you make better decisions about your diet.
