Obesity and being overweight are two common health risks facing truck drivers. Obesity means having too much body fat, while a person can be overweight due to too much muscle, bone, fat, and/or body water. If a person consumes more calories than he/ she burns, those extra calories are stored as fat. Over time, if life changes are not made, that excess body fat will continue to increase until a person reaches obesity. When that happens, there is an increased risk of heart disease, stroke, diabetes, etc. The good news is that obesity is reversible in most cases, by eating and drinking smarter and increasing your physical activity. Consider the chart below and ask yourself where the majority of your daily calories are coming from.
