"The human body is not equipped to handle this much calories. One way or another, things have to change," the doctor words sunk into Genji's ears.

He remembers the intense feeling of withdrawal.
"My body really was asking for richer and fattier foods," he said.
It was a struggle to resist delicacies like pizza and pasta, or even pantry staples like rice and bread.
But Genji felt like his diets and treadmill runs were getting him nowhere -- literally. "I just felt like a hamster on a wheel, the only thing missing was the water bottle," he recalled.
He was introduced to Dr Okatsu Edu by Ayano's friend, Miko due to his frustrations. Being a plumpy person herself in the past, Miko told Genji on how she became slender.
"Everybody thought that it was through the traditional diet and exercise; it was far from it."
