BMR 1,333 Calories per day
Your body will burn 1,333 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, 1,333 Calories per day (6 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.
How Many Calories to Lose Weight
If you are trying to lose weight, then you need to reduce your calories. You can do this by consuming (eating) fewer calories, or increasing your activity to burn more calories, or a combination of both.
At 1000 calorie reduction, this would be 2 pounds (1 Kg) per week of weight loss. We recommend that you try to lose 1 or 2 pounts a week and no more. Studies have shown that a quicker weight loss often leads to additional weight gain one the diet is done.
Calorie needs to Maintain Weight
Once you have determined your BMR (1,333), 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.
Calorie needs to Gain Weight
To gain weight, you need to take more calories than your total energy needs.
If you eat more calories than your body metabolism needs for your activity level, you will gain weight.
There are 3,500 calories in every pound of body fat (0.5 Kg). So, if you eat 500 calories more a day than your body needs, you will gain one pound every week.
