"USDA recommends the average no. calories per person per day is 2,500 calories (2,000 for women and 3,000 for men), of which about 50% is from carbohydrates, 22.5% from proteins, and 27.5% from fats. This means the source of calories for a person per day is: 1,250 calories is from carbohydrates 562.5 calories is from proteins 687.5 calories is from fats"
