What Are Macronutrients?

Macronutrients (macros) are the three main nutrients your body needs in large amounts: protein, carbohydrates, and fats. Each plays a unique role in your body's function, and getting the right balance is crucial for achieving your health and fitness goals.

Unlike simple calorie counting, macro tracking ensures you're not just hitting your calorie target, but also providing your body with the right nutrients in the right proportions for optimal performance and body composition.

Frequently Asked Questions

How accurate are macro calculators?

Macro calculators are 85-90% accurate for most people. Individual variations in metabolism, activity level, and body composition can affect actual needs, so monitor your results and adjust accordingly.

Should I hit my macros exactly every day?

Aim to hit your targets within 5-10 grams for each macro. Don't stress about being perfect every day - consistency over time is more important than daily perfection.

Can I eat whatever I want if it fits my macros?

While IIFYM (If It Fits Your Macros) can work, prioritize whole, nutrient-dense foods for better health, satiety, and long-term success. Save treats for 10-20% of your calories.
