Do Thai girls EAT?

Hello all! I have recently completed my trip to Thailand, and will be blogging more about it soon…but I would just like to start this blog by addressing an observation upon arriving in Bangkok for a few days…. Do Thai girls Eat???? Everywhere we went, I can’t help but notice that most of the younger ladies in this city are stick thin!!! Every year I visit their getting skinnier and skinnier. What are they eating? What aren’t they eating? There’s food and snacks everywhere! If I lived here for three months I’ll probably gain 300 pounds! I couldn’t walk down the street without buying some kanom/desserts to sample. So many food stalls, restaurants, how can they possibly stay so thin?? Has anyone ever pondered this?
