Macro Calculator determines optimal macronutrient ratios for your fitness goals, calculating protein, carbohydrate, and fat needs based on your body and activity level.
What are Macronutrients?
Macronutrients (macros) are the three main nutrients your body needs in large amounts: proteins, carbohydrates, and fats. Each plays a crucial role in health and fitness.

Frequently Asked Questions
How do I calculate my macro needs?
Determine your total daily calories, then distribute them according to your goals. Multiply protein/carbs by 4 and fat by 9 to get calorie amounts.
What are the best macro ratios for weight loss?
For weight loss, aim for 1.6-2.2g protein per kg, 2-4g carbs per kg, and 0.8-1.2g fat per kg, adjusted to create a calorie deficit.
Should I track macros daily?
Daily tracking helps ensure consistency, but weekly averages are also effective. Focus on hitting macro targets over the course of each week.
