It is important to note that these guidelines are not hard rules; stressing over specific percentages, grams, milligrams, is counterproductive.
Generally, 45-65 percent of your daily calories should come from carbohydrates. This may be higher if you're an athlete or lower if you're more sedentary. The 2015 Dietary Guidelines recommend less than 10 percent of these carbohydrates coming from added sugar [40].
These guidelines also recommend that 10-35 percent of total calories should come from protein for a typical adult, or 0.8 grams per kilogram of bodyweight [41].
The average healthy adult's total daily fat intake is suggested to be between 20 and 35 percent of total calories. The American Heart Association recommends less than 7 percent of these fats to come from saturated sources, and less than 1 percent from trans fats. [42].
