No, not you, Tyra Banks! You are looking positively svelte on this cycle of ANTM, even adroitly covering up your "vagina arms" most of the time. (Your stank attitude is another story—that moment on last night's episode when you corrected Twiggy's pronunciation of "Bianca" was salty. She has a British accent, okay?) Anyway, Intern Mary has compiled the body mass indexes of every contestant on every cycle since the dawn of America's Next Top Model. A BMI of below 18.5 is considered underweight, fyi.
