Frequently Asked Questions

What are macros and why should I track them?

Macros (macronutrients) are protein, carbohydrates, and fats — the three nutrients your body needs in large amounts. Tracking macros ensures you get the right balance for your goals, whether that's building muscle, losing fat, or improving performance.

What is the best macro ratio for weight loss?

A common weight loss ratio is 40% protein, 30% carbs, and 30% fat. Higher protein helps preserve muscle while losing fat. However, the best ratio depends on your activity level, preferences, and how your body responds.

Do I need to hit my macros exactly every day?

No — aim to be within 5-10g of each target. Consistency over the week matters more than hitting exact numbers daily. Focus on protein first, then fill in carbs and fats based on your preferences.
