Many people equate lower weight with better health, when in actuality the numbers on the scale are not an adequate method for determining a person’s health. The number on the scale is not adequate because it fails to take into account muscle, bone and fat composition within the body. BMI (Body mass index), measures a person’s height in relation to weight, but this measure also fails to take into account the true level of health. Using BMI also fails in determining risk factors for heart disease, diabetes, and various other chronic conditions. Weight loss goals have also been aligned with lower weight and staying within BMI ranges. But even if a person is within the BMI range and has a healthy body fat composition this does not mean they are healthy. It does not take into account that a person can be lean due to unhealthy behaviors, such as extreme dieting. A new study has shown that a person’s mortality rate increases with a higher body fat percentage. This should be considered a wake up call because even a mildly overweight person can be at a greater risk if their body fat percentage is too high. Also one should consider that even though they are at an ideal weight and BMI range, it is certainly not a healthy formula for longevity. Instead it is actually better to be a little over weight and focus on living a healthy lifestyle with no extreme measures.
