How to use these numbers
Percentages of daily value are calculated from the FDA Daily Values used on US nutrition labels, which assume a 2,000 calorie diet; your own targets may be higher or lower. If you want the values for your own body weight and activity level rather than a reference diet, the protein and macro calculator turns a calorie and protein target into numbers you can use.
