What Are Macros?

Macronutrients are protein, carbohydrates and fat — the three nutrients your body needs in large amounts. Tracking macros is more flexible than counting calories because it focuses on food quality, not just quantity.

What Are Macros?

Macronutrients (or macros) are the three nutrients your body needs in large amounts: protein, carbohydrates, and fat. Each plays a unique role in your body, and tracking macros is more flexible than counting calories because it focuses on food quality.

Protein (4 kcal/g): Builds and repairs tissues, supports immune function, and keeps you full. Aim for 1.6–2.2 g per kg of body weight for active individuals. Good sources: chicken, fish, eggs, Greek yogurt, tofu, lentils.

Carbohydrates (4 kcal/g): Your body's primary energy source. Complex carbs (oats, quinoa, sweet potatoes, vegetables) provide sustained energy and fiber. Simple carbs (sugar, white bread) cause energy spikes and crashes.

Fat (9 kcal/g): Essential for hormone production, vitamin absorption, and brain health. Focus on unsaturated fats: avocados, nuts, olive oil, fatty fish. Limit saturated and trans fats.

How to Track Macros

The easiest way is using an AI-powered food tracker. Manual macro logging is tedious and time-consuming. With Kcalibra, simply snap a photo of your meal — the AI identifies the food, estimates portions, and logs protein, carbs, and fat automatically.

Macro recommendations are general guidelines. Individual needs vary based on genetics, activity, and health conditions.
