A weight loss calculator can help you compute the fraction of fat lost while on a diet. Online calculators are available to help dieters keep track on the path to achieving weight goals.
All such calculators work on the same formula (with some small variations). Weight loss percentage is equal to the weight in pounds shed during the diet divided by the initial pre-diet weight, multiplied by 100. If the initial weight is 200 pounds and the diet helps you drop 25 pounds, then the percentage of weight dropped will be (25/200)*100 or 12.5%
This means that the diet has helped you lose 12.5% of the weight caused by extra fat in your body. But not all of the loss is fat. A certain amount of muscle mass is also included, though the quantity will vary depending upon whether or not you follow an exercise regimen along with the diet.
A body fat percentage calculator is a special variation of the general one which can help you estimate how much of the weight that was lost was actually made up of fat. One thing to clearly understand is that all the calculations are only estimations and not absolutely perfect measurements. If accuracy is critical, there are other more sophisticated options like skin fold thickness measurements using calipers and hydrostatic weight measuring devices which will serve better.
To use a weight loss calculator, you will need access to the Internet. The process is simple. Just type in numbers based on measurements and click the button to run the calculations. For example, to assess fat percentage loss, you will enter data like total body weight, waist circumference, hip measurement, forearm or arm width and gender into the program.
Using a calculating program to estimate weight loss is not complex. There are no calorie estimations or meticulous record keeping of intake or weight history that are required to use these simple online scripts. The weight loss calculator can offer guidelines on the amount of food or total calories that one can eat in order to reach specific weight targets. Some of the more sophisticated scripts even break down the total requirements by category, suggesting recommended quantities of carbohydrate, fat and protein to include in the diet.
In essence, weight loss boils down to burning off more calories than consumed. Basal Metabolic Rate (BMR) is a measure of the amount of energy that your body burns while at rest. Weight loss calculators are helpful in calculating BMR based on measurements such as height, weight, body fat percentage and other metrics. These provide a helpful guide in planning diets and activities to lose weight.
