How to Use the Macro Calculator
Enter your daily calorie target (use our BMR Calculator to find it) and choose a macro split that matches your goal — balanced, weight loss, muscle gain, keto, or low-carb. The calculator converts percentages into exact grams for each macronutrient.
WHO Recommended Parameters
The World Health Organization (WHO) diet guidelines emphasize a balanced approach, strongly recommending that total fat intake should not exceed 30% of total energy intake, and free sugars be reduced to less than 10%.
FAQs
What are macronutrients and what does the WHO recommend?
Macronutrients are the main nutrients your body needs: Protein, Carbohydrates, and Fat. The World Health Organization (WHO) guidelines emphasize a balanced approach, recommending that total fat intake should not exceed 30% of total energy intake to prevent unhealthy weight gain. Furthermore, the WHO strongly recommends that free sugars be reduced to less than 10% of total energy intake.
How much protein do I need per day?
According to general health guidelines, 0.8g per kg of body weight is appropriate for sedentary individuals. For active individuals, 1.2–2.2g per kg helps support muscle maintenance and growth.
How do I align my macros with World Health Organization parameters?
The WHO suggests avoiding extremes. Our 'Balanced' macro split closely reflects their recommendations by keeping fat around 25-30%, providing a moderate protein intake, and leaving the remainder for complex carbohydrates. To strictly follow WHO advice, ensure your carbs come predominantly from whole foods rather than free sugars.
