According to Penn Medicine, a person on a 2,000-calorie-per-day diet should eat up to 65 grams of fat. The amount of fat a person eats in a given day depends on his level of activity, age and daily caloric intake.
Women between the ages of 19 and 50 can consume up to 73 grams of fat per day, according to Penn Medicine. This recommendation is based on the average daily caloric intake for women between the ages of 19 and 50, which is 2,200 calories. Men between the ages of 19 and 50 can consume up to 97 grams of fat, which is based on average daily caloric intake of 2,900 calories.
