Macro Calculator

A macro calculator is a tool that helps you determine your specific macronutrient needs based on your personal characteristics like:


Gender, age, weight, height and activity level.

The macro calculator will give you the amount of protein, carbohydrates, and fats YOU should consume daily to reach your Health and Fitness goals.


This code uses the Harris-Benedict equations to calculate the Basal Metabolic Rate (BMR), which is the number of calories a person needs to maintain their weight while at rest. The BMR is then multiplied by an activity level factor to get the total daily energy expenditure (TDEE). Finally, it calculates the macronutrients (protein, carbs, and fat) based on the TDEE using the commonly used ratios.

Please note that this is just an example, and the values of macronutrients used here are based on some assumptions, and there are many other methods available to calculate the personalized macros, the nutritional needs can vary from person to person. It is always recommended to consult a medical professional or a licensed dietician for a personalized nutrition plan.
