How do anorexics keep from fainting?

[makeupfreak72]

i'm so curious, i see all these skinny actress's who are obviously anorexic, but here's my question that i want to get opinions on, how in the HELL do they keep from fainting, and how do they function? and stay alert? i'm overweight and if i skip a meal i swear i feel like i'm gonna pass out. just curious.
