: Statistics can reveal mathematical relationships between different things, and these relationships might, or might not, explain what is going on. A standard measure of body weight is the body mass index, or BMI, which is calculated using height and body weight. Being classified as overweight means that one’s weight is above one’s ideal, but not obese. As a general statement -- and based solely on BMI -- being in the overweight group does not add to mortality risk when compared with being of ideal body weight. This means we need to focus on building and maintaining healthful habits during early adulthood -- and even more so as we transition to our middle-aged years and beyond, as these are the times of creeping body weight.
