If 3,500 calories equals about 1 pound (0.45 kilogram) of fat, you have to burn about 3,500 calories to lose 1 pound.
So if you cut about 500 to 1,000 calories a day from your typical diet, you’d lose about 1 to 2 pounds a week.
What Does the Calorie Calculator do?
The Calorie Calculater calculates how many calories you need to consume to gain or lose weight. In step 1 of the Calorie Calculator you can input your height, age, gender, weight and your activity level. This information is used to calculate your total daily calorie expenditure. (Calories are a way to measure energy consumed). In step 2 of the Calorie Calculator you can input how much weight you want to gain or lose.
Based on this information the Calorie Calculator creates a calorie surplus or a calorie deficit in your diet that will help you achieve your target weight. Depending on how much weight you want to gain or lose you can adjust your calorie intake or your activity level to achieve your desired result.
What is your BMI?
Your BMI is a measurement of your body weight based on your height and weight. Although your BMI does not actually “measure” your percentage of body fat, it is a useful tool to estimate a healthy body weight based on your height. Due to its ease of measurement and calculation, it is the most widely used diagnostic indicator to identify a person’s optimal weight depending on his height. Your BMI “number” will inform you if you are underweight, of normal weight, overweight, or obese. However, due to the wide variety of body types, the distribution of muscle and bone mass, etc., it is not appropriate to use this as the only or final indication for diagnosis.
