Do Calorie Requirements Vary From Person to Person?
As unfair as it may seem, the number of calories that are required for an individual to maintain body weight varies significantly from person to person. There are many different factors that affect the situation, and it can often be a struggle for a person to figure out the right dietary program to ensure that he is getting enough calories to keep from losing weight, but not so many that they start to gain weight. This is a problem that affects almost everyone, from those who want to gain weight to those who want to lose it, and even those who just want to maintain their current weight.
What Variables Affect a Person's Daily Calorie Requirement?
There are many variables that affect how many calories a person burns each day, and how many they need to eat to maintain a static weight. Some of the most important variables are age, gender, weight, height, activity level, and genetic metabolism. All of these factors, combined into one picture, can give a good idea of how many calories a person needs to eat each day to maintain body weight. The final result is, however, only an estimation, and the truth is that no one ever really knows for sure how many calories they burn, exactly, in a given period of time.
How Many Calories Does an Average Person Have to Eat Each Day to Maintain Their Weight?
An average 25 year old man, defined here as weighing 160 lbs and standing 5' 10" tall, burns about 2060 calories per day while leading a sedentary lifestyle. That same man would burn 2661 calories if he led a moderately active lifestyle and 3262 calories if they were extremely active. An average 25 year old woman, on the other hand, is defined here as standing 5' 5" and weighing 130 lbs. Such a woman would burn 1766 calories each day while sedentary, 2282 with moderate activity, and 2797 with extreme levels of activity. In order to maintain their current weight, the individuals would need to eat as many calories each day as they burned.
