One hundred years ago today Alfred Wegener presented his Continental Drift hypothesis to much derision and scepticism. Alfred Wegener first thought of this idea by noticing that the different large landmasses of the Earth almost fit together like a jigsaw.
BMI readings under 18.5 mean you are underweight, and could put on a few pounds. If you fall between 18.5 and 24.9, youâre considered normal, while a BMI of 30 or higher qualifies as overweight. But in recent years, more researchers argue that itâs not the most accurate way to measure body weight. For years, scientists have said that BMI canât distinguish between fat and muscle, which tends to be heavier and can tip more toned individuals into overweight status, even if their fat levels are low.
Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI is a fairly. reliable indicator of body fatness for most people. BMI does not measure body fat directly, but. research has shown that BMI correlates to direct measures of body fat. BMI can be considered an. alternative for direct measures of body fat. Additionally, BMI is an inexpensive and easy-to-perform. method of screening for weight categories that may lead to health problems.
