Some Bulgarian women simply  have that gene type 'I'll be thin as a pencil, no matter how much or what I eat', but mostly I think it's all about the stress and the chores a Bulgarian woman at middle age has in her life.I'm a 18 year old Bulgarian,I do ballet and normally I weight about 58 kg with normal eating and all the excercise I get every day.My mom (God bless her) doesn't have the time to do even one sit-up,she eats more than me sometimes(including banitza,croissans and chocolate),works her bud off in the office and she's thin like a supermodel..Stress is the best way to lose weight :(
