What is a Weight Loss Calculator?
A Weight Loss Calculator is a simple tool that helps you know how long it may take to lose weight. You enter your current weight, goal weight, and daily habits. The calculator then shows an estimated time to reach your goal. It makes weight planning easy to understand.
What Does Weight Loss Mean?
Weight loss means reducing body weight in a healthy way. It usually happens when your body uses more energy than the food you eat gives. This tool only shows estimates and helps you learn how weight change works.
How This Weight Loss Calculator Works
First, you enter your current weight and your goal weight. Then you add details like age, gender, height, and activity level. You also enter how many calories you eat each day. When you click calculate, the tool compares your calorie intake with your body needs.
What Formula Is Used in This Calculator?
This calculator uses the Mifflin St Jeor formula to estimate daily calorie needs. It first calculates BMR, which means how many calories your body needs at rest. Then it multiplies BMR by activity level to get total daily energy use. Weight loss is calculated using the rule that about 7700 calories equal one kilogram of body weight.
Simple Example for Easy Understanding
If your body needs 2200 calories per day and you eat 1800 calories, the difference is 400 calories. Over time, this calorie gap helps reduce weight. The calculator uses this idea to estimate days, weeks, and months.
