If A 15 Year Old Girl Who Is 5.2 Has 800 Calories A Day Is This To Little Or To Much? How Many Calories Should A Teen Girl Eat Each Day To Loose 1.5 Pounds A Week? Please Only Answer If You Realy Know What Your Talking About
800 calories/day is too low for either a woman or a man.
As a woman you don't want to dip below 1,200 calories/day and as a man, 1,500 calories/day.
To lose 1.5 pounds/week, you will need to create a weekly caloric deficit of 5,250 calories.
First what you're going to have to do is take your weight in pounds and multiply that by 15 to get your maintenance caloric intake..the amount of calories you need daily to MAINTAIN your current weight.
Ex: 150lb x 15 = 2,250 calories/day.
To start, you'll want to subtract 500 calories from this number to lose at least 1 pound a week, since 500x7 days = 3,500, which is the amount of calories needed to burn 1 pound.
In order to burn that extra 1/2 a pound, you'll need to do 1 hour of cardio 4 days a week. 1 Hour of cardio will burn about 400-600 calories.
Of course you could lose that extra 1/2 a pound by reducing your calorie intake further as well, that much is up to you.
