Most dieters are familiar with Body Mass Index (BMI), but few know how it is calculated and use online tools when needed. Nevada professor George Fernandez has released a much simpler formula he calls Maximum Weight Limit (MWL) which can be used as a weight limit which should not be exceeded. "We need a "Maximum Weight Limit, or MWL," he said, "one number that we know we can't go over, just like a speed limit." His formula takes a base value of 175 pounds for a 5 foot 9 inch male and adds or subtracts 5 pounds for every inch taller or shorter you are. The base numbers for a female are 5 feet even and 125 pounds. My height is 5'11'' so we would add 10 pounds to the base 175 pounds and my MWL would be 185 pounds. When using the BMI calculation, the weight at which I would be considered overweight is 179 pounds.
So, which calculation should you use for your weight loss goals? Both calculations can be inaccurate for very muscular people or elderly people because their weight will not be reflective only of their height. These numbers can be used as a basis for your initially setting your weight loss goals, but you should evaluate your progress and adjust your goal weight based on how comfortable you feel at your current weight in relation to either your BMI or MWL. If you are approaching either weight, you can most likely move into maintenance mode of an Atkins style diet and begin to level out your weight loss in order to maintain for the rest of your life.
