Mathematics to solve everyday problems


Although many people apply mathematics to solve problems, even everyday problems, I do not. Because I have no love for math, I am more entitled to solve a problem using logic rather than numbers and equations. I am the opposite of Carson C. Chow who deploys mathematics to solve the everyday problems of real life. As an investigator at the National Institute of Diabetes and Digestive and Kidney Diseases, he tries to figure out why 1 in 3 Americans are obese. It is common sense to know that what you eat affects your health and weight. It is safe and true to say that America has the most obese people compared to other nations and that can now only be blamed on the type of food people eat. Because to do this experimentally would take years, researchers have developed models to test human development based on food intake, height, weight, and exercise to predict how much one will weigh. You could find out much more quickly if you did the math says one researcher. Their findings we interesting and some surprising. The body changes as you lose pounds, interestingly, they also found that the fatter you get, the easier it is to gain weight. An extra 10 calories a day puts more weight onto an obese person than on a thinner one. Also, there’s a time constant that’s an important factor in weight loss. That’s because if you reduce your caloric intake, after a while, your body reaches equilibrium. I learned a new thing and that is that it actually takes about three years for a dieter to reach their new “steady state.” The model predicts that if you eat 100 calories fewer a day, in three years you will, on average, lose 10 pounds but that is if you don’t cheat.
