Frequently Asked Questions

What are macros (macronutrients)?

Macronutrients are the three main nutrients your body needs in large amounts: protein (4 cal/g), carbohydrates (4 cal/g), and fat (9 cal/g). Tracking macros helps ensure you get the right balance for your goals while meeting calorie targets.

How much protein do I need?

For most active people, 0.7-1g per pound of body weight is sufficient. Athletes and those building muscle may need 1-1.2g per pound. Sedentary individuals can often maintain with 0.36g per pound. This calculator adjusts based on your goals.

What is the best macro ratio for weight loss?

A higher protein ratio (30-40%) helps preserve muscle while losing fat. Moderate carbs (30-40%) provide energy, while healthy fats (25-35%) support hormones. The key is maintaining a calorie deficit while getting adequate protein.

Should I track macros or just calories?

Tracking calories works for weight management, but tracking macros optimizes body composition. Hitting protein targets helps build/preserve muscle. Balancing carbs and fats affects energy, satiety, and hormones. Macros matter more for specific fitness goals.

What is the keto diet macro ratio?

The ketogenic diet typically uses 70-75% fat, 20% protein, and 5% carbs (usually under 20-50g carbs daily). This extreme low-carb approach forces your body to burn fat for fuel (ketosis). It's effective for some but difficult to maintain.

How accurate is this macro calculator?

This calculator uses the Mifflin-St Jeor equation, which is accurate for most people within 10%. Individual metabolism varies based on genetics, muscle mass, hormones, and other factors. Use these numbers as a starting point and adjust based on results.
