How many calories should I eat to lose weight?

The amount of calories we should all eat each day to lose weight is not as easy as a magic number. To answer this question we will have to examine a few factors because caloric needs are based on several factors

Step one is to determine the amount of calories you can eat to stay at your current weight which is the amount of energy your body needs to function. To do this there is a simple formula called the Harris-Benedict principle. This formula will provide you with your base metabolic rate, also known as your BMR.

Women: BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years)

Men: BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age in years)

Step two is to incorporate your daily activity into your caloric needs.

If you are sedentary: BMR x 1.2
If you are lightly active: BMR x 1.375
If you are moderately active - exercise most days the week: BMR x 1.55
If you are very active - exercise daily: BMR x 1.725
If you are extra active - hard labour or are in athletic training: BMR x 1.9

Though not perfect this method will let you know how many calories you need to maintain your current weight at your present activity level. This is a good starting place with respect to your weight reduction plan.

This formula has provides a guide to a persons daily energy needs. It is just a guide and is used a starting point on your journey to a healthy slimmer body.
