According to the Academy of Nutrition and Dietetics, the average 14-year-old male needs about 2,200 to 3,200 calories per day, and the average female needs about 1,800 to 2,400 each day. However, variables such as height, weight and activity level need to be taken into account when determining caloric needs for teenagers. Caloric intake is important for managing body weight, which is crucial for teenagers who are overweight or obese.
Recommendations for Males
Each 14-year-old's optimum caloric intake differs according to their personal activity level. Males who are 14 and sedentary, which means they only do light activity necessary for everyday life, such as walking to the mail box, should consume 2,000 to 2,400 calories per day. Moderately active males who are 14, or those who walk quickly for about 1.5 to 3 miles each day, should consume 2,400 to 2,800 calories each day. Active males who are 14, those who play sports or walk more than 3 miles each day, should consume 2,800 to 3,200 calories a day.
Recommendations for Females
On average, females need fewer calories than males. The current USDA guidelines recommends that sedentary 14-year-old females consume 1,800 calories each day. Females who are 14 and are moderately active should consume 2,000 calories in a day. Active females who are 14 are advised to eat 2,400 calories a day, the same amount as a sedentary or moderately active male.
