If you're having trouble sticking to your diet plan, try using a weight loss calculator. Seeing changes as they happen may be all the motivation you need to stay on track. Many people use calculators to put their weight loss in perspective: if you have a set goal, you can reach it at a pace you're comfortable with while still enjoying all the benefits.
There are several types of weight loss calculators, and it's important to choose the right one for your weight loss program. Here are some of the most popular:
Body mass index (BMI)
The World Health Organization (WHO) uses BMI to calculate the amount of body fat in proportion to muscle, bone, and other body constituents. It calculates the ratio of your weight and the square of your height, and compares it against a chart of 'ideal' BMIs. Your body fat level tells you two things: how much you are at risk, and how hard you'll have to work to gain your ideal weight. This weight loss calculator is ideal for people trying to fight obesity.
Glycemic index (GI)
In a GI test, a 50-gram portion of food is tested to determine how much of the carbohydrate is converted into glucose. Doctors often use it to design ideal diets for their patients. It can also be used as a weight loss calculator by people with special dietary needs, such as diabetics and those with kidney disease.
Waist-to-hip ratio (WHR)
WHR is simply the ratio between your height and your weight. It is considered the easiest yet most effective weight loss calculator, recommended by most doctors as a home self-test for their patients. It measures body fat composition, a major indicator of health risk, and may be used to supplement BMI test results. The ideal WHR is 0.90 for men and 0.85 for women.
