This tool is excellent for determining three factors about your body’s weight and metabolism. These factors include Basic Metabolic Rate (BMR), Body Mass Index (BMI), and Ideal Body Weight (IBW).
Basic Metabolic Rate (BMR)
This factor of your health is the most important of the three indicators, and quite possibly, the most important factor relating to weight loss. Your BMR determines how many calories your body burns throughout one day. This takes into account your age, weight, height, and activity level.
The tool gives you three total caloric intake amounts. Maintenance means that if you eat this amount of calories, you will neither gain nor lose weight. This can be important to know when you have reached your goal weight. The next two caloric intake amounts are suggested for weight loss. You should never eat below your “Extreme Fat Loss” caloric amount. This can result in your body starving itself, which includes muscle loss and the storing of fat, being very counterproductive.
Since your weight will change frequently on your weight loss journey, it is important to consistently calculate your new BMR. You will notice that these numbers will get lower and lower as you become less and less hungry.
Body Mass Index (BMI)
This factor is not entirely important to your health. Body Mass Index is only a general indicator of what your body weight should be based solely on the relation between weight and height.
Where BMI truly fails is that it cannot determine what unique body type you may have (Endomorph, Mesomorph, or Ectomorph). You may be jacked with muscle and your BMI will tell you that you are overweight. This indicator should only be used as a general reference.
Ideal Body Weight (IBW)
This factor is the least important of the three. Your IBW should only be used as a reference. This tool will give you a range of weights in which you should follow the upper-end of these ranges.
