BMR 2,300 Calories per day
Your body will burn 2,300 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, 2,300 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.
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.
Calories required to Maintain Weight
This calculation gives you the number of calories you burn in one day at your current level of activity. In other words, this is the number of calories it takes to stay at the weight you are if you don’t change anything.
If your activity level is sedentary (Little or no exercise and desk job), you need to multiply your BMR by 1.2, Lightly Active (Light exercise or sports 1-3 days a week) x 1.375, Moderately Active (Moderate exercise or sports 3-5 days a week ) x1.55 , Very Active (Hard exercise or sports 6-7 days a week) x1.725, and Extremely Active (Hard daily exercise or sports and physical job) x1.9.
Calories required to Gain Weight
If you want to gain body weight, you need to consume more calories than you burn.
One pound (0.5 Kg) of body weight is roughly equivalent to 3500 calories, so eating and extra 500 calories per day will cause you to gain one pound a week.
If you increase your calories to gain weight then gradually increase your level of physical exercise in order to maintain or increase your level of body mass.
