BMR means Basal Metabolic Rate.It is used to estimate how many calories you should consume.By using a simple formula called the Harris-Benedict principle, you can assess your BMR.

Your BMR is the amount of energy your body needs to function.Then, to lose weight, you'll need to cut calories or burn extra calories and shoot for a level lower than the results you get with this formula.

We use about 60 percent of the calories we consume each day for basic bodily functions such as breathing.Other factors that influence your BMR are height, weight, age and sex.

Step One : Calculate your BMR with the following formula:

• Women: BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years)
• Men: BMR = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age in years)

Step two : In order to incorporate activity into your daily caloric needs, do the following calculation:

• If you are sedentary : BMR x 1.2
• If you are lightly active: BMR x 1.375
• If you are moderately active (You exercise most days a week.): BMR x 1.55
• If you are very active (You exercise daily.): BMR x 1.725
• If you are extra active (You do hard labor or are in athletic training.): BMR x 1.9

### Create a Calorie Deficit:

In order to lose weight, you must create a calorie deficit. It is easier and healthier to cut back your calorie intake a little bit at a time.

Every 3,500 calories is equivalent to 1 pound.

If you cut back 500 calories a day, you will lose 1 pound per week.

If you exercise to burn off 500 calories a day you will also lose 1 pound per week.

Ideally, you should do a combination of both, (e.g. cut back 250 calories; burn an extra 250 calories).

### Lose at a Healthy Rate:

A healthy weight loss goal is to lose 0.5 to 2 pounds per week. Losing more than 2 pounds per week will mean the weight is less likely to stay off permanently. Never cut back to fewer than 1,200 daily calories without medical supervision. To find out how you are spending your current calorie intake, keep a detailed food diary for at least one week.

Making little changes like these will really add up in the long run.
