i'm 5'6" and a 1/4. my doctor says the quarter makes a difference with BMI. i don't care about my BMI. but i do know that me at 139 pounds is scary. i lost a shitload of weight when my ex cheated on me and we broke up. my aunt thought i had an eating disorder; i looked gross. i think it depends on your body type. i look a lot better around 150.
