Macros (macronutrients) are the three main nutrients your body needs in large amounts: protein, carbohydrates, and fat. Each provides energy (calories) and serves different functions. Protein builds and repairs tissue, carbs provide energy, and fats support hormones and cell health.

How are macro targets calculated?

Macro targets are calculated by first determining your daily calorie needs (TDEE), adjusting for your goal (deficit for fat loss, surplus for muscle gain), then splitting those calories into protein, carbohydrates, and fat based on your chosen ratio. Each gram of protein and carbs provides 4 calories, while each gram of fat provides 9 calories.

What is the best macro ratio?

There is no single "best" ratio — it depends on your goals. A balanced ratio (30% protein, 35% carbs, 35% fat) works well for most people. Higher protein (40/30/30) supports muscle building. Low carb (40% protein, 20% carbs, 40% fat) can help with fat loss. Experiment to find what works for your body.

How much protein do I need per day?

For general health, 0.8g per kg of body weight is the minimum. For active individuals aiming to build or maintain muscle, 1.6-2.2g per kg is recommended. This calculator factors in your activity level and goals to give personalized targets.

Should I track macros or just calories?

Tracking macros is more effective than tracking calories alone. Two diets with the same calories but different macro splits can produce very different results. Adequate protein preserves muscle, sufficient fat supports hormones, and carbs fuel performance.

How do I track my macros over time?

Use a food tracking app connected to Huvolve to log your meals and monitor your macro intake. Huvolve aggregates nutrition data from apps like MyFitnessPal and Cronometer, giving you a unified view of your nutrition alongside your fitness data.

What are Macronutrients?

Macronutrients are the three primary nutrients your body needs in large quantities: protein, carbohydrates, and fat. Each macro plays a unique role in your body and provides a different amount of energy per gram.

The Three Macronutrients

Protein (4 cal/g): Builds and repairs muscle, supports immune function, enzymes, and hormones. Found in meat, fish, eggs, dairy, legumes, and tofu. Carbohydrates (4 cal/g): Your body's primary energy source. Fuels the brain, muscles, and central nervous system. Found in grains, fruits, vegetables, and legumes. Fat (9 cal/g): Supports hormone production, nutrient absorption, cell structure, and brain function. Found in oils, nuts, avocado, fatty fish, and dairy.
