How Cows Affect Calories

Average teenagers (moderately active) need around 1500 to 1800 calories a day but to specifically determine your intake you must calculate how many calories your body needs to function (BMR(yay acronyms...wait no...nevermind...)) and factor in the amount of excercise you do. Teens who are more or less active will have different estimate because their bodies need more energy because they do more. This site is an easy way to figure out your recommended calorie intake (this is for those of us who can't do math even though all of the teachers insist that we "just aren't reaching our full potential and just need to study more"(for the intense math geniuses you can find the actual numbers here)). You can also find out how many calories you actually take in by finding out how many grams of protein, fat, and carbs you eat a day. There are 4 calories per gram of protein and carbs and 9 calories per gram of fat.
