Carbohydrates are the necessary ingredient of your daily diet. The carb intake calculator helps to evaluate the daily requirement of carbohydrates to fulfill body demands. You cannot neglect the daily demand for carbohydrates. In addition, carbohydrates are the rich source of several foods and come in the form of starches, sugars, and fibers. Moreover, carbohydrates should provide approximately 45 to 65% of daily calorie intake.

According to the carb intake calculator, a minimum carb intake of 130g daily is beneficial for adults. A rough estimate dictates that 1g of carbohydrates offer 4 Kcal of energy.

  • The minimum recommended percentage of calories from carbohydrates should be 45%. It states that almost half of your body’s energy should come from carbohydrates. You can calculate the minimum lower levels of carbohydrates with a carb intake calculator.
  • The maximum recommended percentage of calories from carbohydrates should be 65%. Exceeding this limit, you may lack other macronutrients like protein, fats in your body. A carb intake calculator will suggest to you the best amount of carbohydrates according to your physical activity.

What are the types of carbohydrates?

Carbohydrates are ranging from simple sugars to complex starches and fibers. There are three common types of carbohydrates known as simple sugars, starches, and fibers.

BMR (females) = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) +5
BMR (makes) = 10 × weight (kg) + 6. 25 × height (cm) – 5 × age (years) – 161

These formulas will help you to determine your daily calorie intake. If you divide the given answer by 4, it will provide you with the carbohydrate intake in grams. As 1g of carbohydrate provides 4 Kcal of energy.

This formula can further accurate the calorie demand or carbohydrates intake according to your physical activity. The physical activity options are:

  • Sedentary or no / little exercise
  • Exercise of 2-4 times per week
  • Moderate level exercise of about 4 times per week
  • Active exercise of about 5 times per week
