ER physician Dr. Travis Stork feels that the BMI chart is "not the end all be all." He suggests using a measuring tape in order to get a good indication of your abdominal fat. He goes on to explain that ideally, your waist should be less than half of your height measured in inches.

He says, in general, women with a waist bigger than 35 inches and men with a waist bigger than 40 inches could be at risk for weight-related health issues.
