BMR 2,439 Calories per day
Your body will burn 2,439 calories per day if you stay in bed all day.
Your body uses energy no matter what you are doing, even when sleeping.
Your Basal Metabolic Rate is the number of calories you would burn if you stayed in bed all day. Your body uses approximately, 2,439 Calories per day (10 Kilojoules / day).
The Basal Metabolic Rate is measured under very restrictive circumstances while awake.
An accurate BMR measurement requires that a person’s sympathetic nervous system is inactive, which means the person must be completely rested.
Calories required to Lose Weight
One you know your Basal Metabolic Rate (2,439) and the number of calories you burn for your activity level, you can improve your weight-loss efforts by setting a lower daily calorie-intake limit and crafting a plan for increasing your physical activity.
If you want to lose weight, you have to consume fewer calories than you burn with your activity level
One pound (0.5 Kg) of body fat is approximately 3500 calories, so to lose one pound per week, you might decrease your required calories by 500 per day.
Calorie needs to Maintain Weight
Once you have determined your BMR (2,439), you can multiply this number by the activity level that most suits your lifestyle, to determine the appropriate number of calories you need to consume to maintain your weight.
The more active you are the more calories you will require. This is because you are already burning the calories you need in order to sustain life.
How Many Calories to Gain Weight
If you ingest more calories than you expend, you will gain weight regardless of the types of calories you ingest.
To gain 1 pound of body weight (0.5 Kg) a week, you must increase your caloric intake by 3,500 calories per week (+500/day).
A steady, gradual weight gain is an easier adjustment for your body, making it safer for you.
