About Macro Calculator
Your body needs three primary nutrients to function: Protein, Carbohydrates, and Fats. These are called "Macros". While counting calories helps with weight change, counting macros ensures that weight comes from the right sources—loss from fat rather than muscle, or gain as muscle rather than fat. This calculator creates a personalized plan based on your unique body metrics and activity level.

Frequently Asked Questions
What is the best macro split for weight loss?
A "High Protein" split is often recommended for weight loss to preserve muscle mass while in a calorie deficit. A common ratio is 40% Protein, 35% Fat, and 25% Carbs.
Do I need to hit my macros exactly?
Not necessarily. Consistency is more important than perfection. Try to stay within +/- 5-10 grams of your targets.
Why does protein matter?
Protein is the building block of muscle. Eating enough protein helps you feel full longer and increases the amount of calories you burn during digestion (Thermic Effect of Food).

Understanding Macro Calculator
Macros are calculated based on your caloric needs. Protein and Carbs provide 4 calories per gram, while Fat provides 9 calories per gram. The calculator distributes your total daily calories into these buckets based on your selected diet plan.
