Hello everybody.It's summer time.I losed weight for summer.I losed  weight from 60Kg to 50Kg in mounth,but I was on holiday in Belgium.In Belgium is lots of chocolate.And I weight again from 50Kg to 65Kg.I was so slim and I'm fat now.I am only 160cm tall.

My mother have said : Kate, you are fat again.
