Josie set herself small targets and began to keep track of he progress. Before long, the 16-year-old noticed changes here and there. She adopted a low-carb, no-sugar diet and upped her water intake.

Alongside her dad – who joined her weight-loss journey by shedding the pounds himself – she was able to slim down to 198Ibs through dieting alone.

It was then that she kicked things up a notch by joining a gym.

She said: “Working out at the gym gave me the extra push to reach my goal weight.”

Instead of being a source of envy and depression, Instagram became one of Josie’s strongest motivators. She began to accumulate followers who not only wanted to see her transformation, but also take tips and advice.

“I shared my meals and progress on my Instagram account @nolongerfatjosie. My followers quickly grew, and each was more supportive than the last. ‘You look great!’ They wrote. ‘Mmm, do you have the recipe?’”
