How to use the fiber calculator?

To calculate your recommended fiber intake, follow these instructions:

  • Start by selecting your biological sex;
  • Input your height;
  • Input your current weight;
  • Put in your age;
  • Decide what your activity level is for a typical week;
  • Let the fiber calculator use the information you provided to calculate your recommended daily calorie intake; and
  • Finally, it will use the calories you need to determine what your daily fiber intake should be.

daily fiber intake = daily calories / 1,000kcal * 14g

So, if you typically eat 2,500 calories every day, you should make sure that your meals contain at least 35 grams of fiber, as you can see in the following calculation: 2,500kcal / 1,000kcal * 14g = 2.5 * 14g = 35g
