There is no girl out there who doesn't want to remain slim and sexy but the increase in weight after pregnancy is something which is natural. Women tend to gain weight after pregnancy. How much disgusted would you feel if your partner left you, just because you gained up weight after pregnancy? Meet this woman Liu Yajuan, the single mother who lives in China. After giving birth to their child Liu Yajuan gained 30 extra pounds of weight from 50kg sharp to 90kg's.

According to her husband, he was tolerating everything she did when she used to be skinny. But now, with weight increased he cannot withstand her anymore and gave her divorce. With her sudden weight increment, her self confidence and trust came shattering down. Liu not only lost her marriage due to her weight but also faced health issues and suffers from serious fatty liver disease.

So she decided to make a change and went on Living it Up, a reality-TV weight-loss competition hosted by Shanghai Dragon Television. And as said that you can achieve anything if you work hard for it, Liu achieved first place during the first weigh in on the show, by beating all 13 of her contestants and dropping 7.2 lbs in her first week.
