Charts or online calculators are then used to show a "healthy weight range" given an individual's height that corresponds to the "healthy range BMI." For example, a BMI chart indicates that a healthy range BMI of 19 to 24 translates to a "healthy weight range" of 120 to 150 pounds for a 5-foot, 6-inch individual.
If this sounds way too complicated to you, you're not alone. George Fernandez, a professor of applied statistics and director of the Center for Research Design and Analysis at the University of Nevada, Reno, set out to give people a simpler way of calculating their healthy weight, and one that wouldn't require charts or online calculators. In addition, he doesn't think the "range" approach sticks in individuals' minds.
"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."
So, using SAS software and statistical procedures, he discovered a much simpler way of calculating a Maximum Weight Limit, which closely corresponds to weight recommendations listed on BMI charts. But, you don't need to calculate or know your BMI, nor do you need a chart or online calculator to figure out your Maximum Weight Limit. Fernandez will present his Maximum Weight Limit calculation at the Nevada Public Health Association Conference, 1:30 p.m., Sept. 22 at the University of Nevada, Reno's Joe Crowley Student Union, Room 423.
"It's a very simple calculation that most of us can do in our heads," he explained. For men and women, there is a baseline height and weight. For men, the baseline is 5-feet, 9-inches tall and a Maximum Weight Limit of 175 pounds, meaning that a 5-foot, 9-inch tall man should weigh no more than 175 pounds. For women, the baseline is 5-feet tall and a Maximum Weight Limit of 125 pounds.
"These are nice round numbers that people can easily remember: 5-feet, 9-inches tall, 175 pounds for man; and 5-feet tall, 125 pounds for a woman," explained Fernandez.
From that starting point, you simply calculate how much taller or shorter you are, in inches. Then, if you are man, you add or subtract 5 pounds for every inch you are taller or shorter than 5 feet, 9 inches. So, if you are 5-feet, 11-inches tall, you are 2 inches taller than the baseline of 5 feet, 9 inches. You add 5 pounds for each of those 2 inches, 10 pounds, to the baseline Maximum Weight Limit of 175. So, your Maximum Weight Limit is 185 (175 pounds plus 10 pounds). Women add or subtract 4.5 pounds for each inch they differ from the baseline height of 5-feet tall.
These Maximum Weight Limits correspond very closely to BMIs of 25.5 for men and 24.5 for women. A BMI of 18.5 to 25 BMI is diagnosed as the "healthy range." Fernandez used a slightly lower BMI base for women and a slightly higher one for men because, on average, women have less muscle mass than men. Although some have debated using BMI as a means for calculating healthy weight because it does not take into account factors such as muscle mass, for example, it has been shown to work as a basis for calculating a healthy weight for more than 90 percent of the population and is the most universally used index in weight management programs.
"Now people can calculate their own Maximum Weight Limit, based on the BMI index, but without any calculators or charts," Fernandez said. "And, all they have to remember is that one number, 185 pounds for example, which is easier for most people than retaining a weight range, such as 155 to 185 pounds."
Fernandez also noted that this simple formula could be very useful in medically underserved areas of the world, and for individuals without access to technology and charts.
"Anyone, anywhere can calculate their Maximum Weight Limit if they know their height and this simple formula," he said. "People can calculate this in their heads and remember this."
Nevada's land-grant university founded in 1874, the University of Nevada, Reno has an enrollment of nearly 17,000 students. The University is home to one the country's largest study-abroad programs and the state's medical school, and offers outreach and education programs in all Nevada counties.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
