37-year-old Sara Backstrom from Sweden had weight problems since she was 8 years old. Her situation got worse after she gave birth to her son at the age of 19. She kept piling on the kilograms as she turned to fast-food and ended up weighing 146 kg. But one embarrassing incident in particular pushed her to turn her life around. When she was at a garden store, she sat down on a camping chair and it snapped underneath her. That was a moment when she knew she had to lose weight.
