Carb Intake Calculator

Managing your carbohydrate intake is one of the most important aspects of nutrition, whether your goal is weight loss, maintenance, or muscle gain. The Carb Intake Calculator is a practical and beginner-friendly tool designed to estimate how many grams of carbohydrates you should consume daily based on your body weight, activity level, and fitness goal.

What Is the Carb Intake Calculator and Why Use It?

This tool simplifies the process by using three core factors:

• Body weight

Based on these inputs, it calculates:

• Your total daily carbohydrate intake
