It is recommended that carbohydrates comprise 40‑75% of daily caloric intake.
*The Institute of Medicine recommends 40‑65% of calories from carbohydrates. FAO/WHO jointly recommend 55‑75% of total energy from carbohydrates, with <10% from sugars.
A Carbohydrate Calculator estimates your daily carbohydrate needs based on factors like:
Age
Gender
Height & weight
Activity level
Total daily calorie needs (TDEE)
Dietary goals (e.g., weight loss, maintenance, gain, or specific diet types like low-carb, moderate, high-carb)
Typical Calculation Methods:
Carbohydrates are usually recommended as a percentage of total daily caloric intake:
Low-carb diet: ~10–20% of total calories
Moderate-carb diet: ~40–60%
High-carb diet (e.g., for athletes): ~60–75%
Since 1 gram of carbohydrates = 4 calories, the formula is:
Carbohydrates (g/day) = (Carb Percentage × Total Calories) / 4
