BMR 1,301 Calories per day

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.

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.

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.
