How many grams of protein and fat are needed per day for women?

Based on a 2,000 kcal intake, the Reference Daily Intake (RDI) values are

• 65 grams of total fat,
• 50 grams protein, and
• 300 grams of total carbohydrate.

Under that system, fat accounts for about 30% of total caloric intake. Amounts would be increased proportionally for more active individuals, although endurance athletes will primarily need more carbohydrate.
