Ariana Omipi, from Auckland, became a social media sensation when she shared details of her dramatic weight loss transformation that saw her lose a staggering 50kg in seven months.
Now, the 23-year-old blogger has revealed that she recently had gastric sleeve surgery after she secretly put the weight back on.
Omipi, who lost 50kg by following a ketogenic diet - high fat, low carb - said she did not want to disappoint her Instagram followers.
However, she admitted she struggled to keep the weight off and hid her body online as people kept hailing her as an inspiration for their own weight-loss journeys.
