This body weight loss calculator is for those who have the below questions:
This body weight loss goal calculator is based on the Mifflin St Jeor Basal Metabolic Rate (BMR) Equation. It takes your gender, height, current weight, desired weight and calculates your weight loss goal in the form of target calorie intake per day. It also provides you how long it will take to lose your weight and reach your goal weight. You will also have the option to select your desired calorie deficit to reach your target weight. This acts as a calorie loss calculator to identify the calorie deficit needed to achieve your target weight at the target date.
BMR can be calculated using several formulas. among them Mifflin St Jeor Equation is considered as the most accurate and reliable. This body weight loss calculator uses Mifflin St Jeor Equation for calculating BMR and then multiplies the BMR with the Activity Factor to find the energy needed by the human body every day. Read more about BMR here.
Activity factor is determined by the lifestyle of an individual. Activity factor divides the physical lifestyle of a person into multiple categories. Every category is represented with a numeric factor. multiplying the numeric factor with the calculated BMR will give the daily calorie needed by a person.
|Activity Category||Description||Activity Factor|
|Sedentary||An office worker, who do not have any option to move around and won't do any exercise.||1.2|
|Lightly Active||An office worker, who moves around or will do little exercise every day. (or) Exercising 1 to 3 days per week.||1.375|

Consider a person's daily calorie needed to maintain the weight is 2200 Cal/day. For reducing the weight the calorie needs to be reduced to something like 1800 Cal/day. The question is how to maintain a lower calorie intake per day. There are several ways to achieve a lower calorie intake. They are:
