Question

if a person needs 3,000 calories per day, about how many of those calories should come from complex carbohydrates?

Answer 1

7600 CARBS AND COMPLEX

Answer 2

45-65% of caloric intake shall be carbohydrates.  You should be eating a minimum of 200 grams or more of carbs per day

Explanation:

The US Dietary Guidelines recommend that we get between 45 and 65 percent of our calories from carbohydrates (10). And with the recommended calorie intake anywhere from 1800-3000 calories a day, based on gender, age, and activity level, this translates into at least 200 grams or more of carbs per day
