Calorie counting is an effective way to lose weight. Each person has different caloric needs, which depend on many factors, such as current weight, age, activity level and other metabolic factors.
Calories in a Pound
In order to lose one pound, you will need to eat 3,500 fewer calories than you burn. If you wish to lose one pound per week, then you need to eat 500 fewer calories per day than your body burns through basic bodily functions, activities of daily living and exercise.
Basal Metabolic Rate
Your basal metabolic rate, which is also known as BMR, is a calculation of your body's minimal caloric needs to sustain basic life functions such as respiration, digestion, and circulation. Your BMR is your caloric needs if you stayed in bed all day long. You can use a BMR formula or calculator to determine your body's basic caloric needs.
Activity Levels
Your activity levels also factor into your caloric needs. The Harris Benedict equation at bmi-calculator.net supplies a multiplier that you apply to your BMR to determine how many calories you burn daily that is inclusive of both BMR and activity. To lose weight, you need to eat fewer calories than your Harris Benedict number, but more than your BMR.
