# Weight Loss Calculators

Maintaining or losing weight has never been simpler with the right tools. Weight loss is mostly a mathematical process. One pound of weight is equal to 3,500 calories.

So, whenever your body has a 3,500-calorie deficit, you will lose a pound of weight. However, you first need to know how many calories you need to maintain your current weight. This is why using weight loss calculators make the process simpler.

How Do We Determine the Weight Loss Formulas?

Of course, this isn’t a guessing game. Our calculators are rooted in science and research. There are 3 steps to determining what number of calories you can eat and lose weight.

1) Basal Metabolic Rate (BMR): First, we must establish your basal metabolic rate. Your metabolism expends energy when it is resting at this rate. This is the amount of energy needed for such things like your heart, lungs, and body to function properly. Factors such as your age, gender, height, and current weight determine this rate.

2) Caloric Requirements: To determine your body’s caloric requirements, we refer to the Harris Benedict equation in combination with the BMR. The Harris Benedict equation assigns a number based on your activity level. This number is then multiplied to the BMR. The result is the number of calories you need a day to stay the same weight.

3) Weight Loss: Now that you know the number of calories you can eat a day, you just eliminate 3,500 calories to lose one pound. Since you can’t reduce that many in one day, we divide 3,500 by 7 days to discover the daily amount.

Calculators Make it Easy
