"The human body is not equipped to handle this much calories. You have to find a way to burn the same amount of calories that you've consumed, DAILY," the doctor words sunk into Cara's ears.
Hearing this, she started making a conscious effort to watch her portion sizes and to do some exercise.
She remembered the intense feeling of withdrawal.
"There is no cure for PCOS. There's nothing that can be done to kept my appetite at bay," she said.
It was a struggle to resist delicacies like pizza and pasta, or even pantry staples like rice and bread.
But Cara felt like her diets and treadmill runs were getting her nowhere -- literally. "I just felt like a hamster on a wheel, the only thing missing was the water bottle," she recalled.
But when modern medicine failed Cara, hope found her.
She was introduced to Dr Okatsu Edu by Ilsa Baker, who was recently known as UK's Hottest Eater. "It turns out my family has contacted Ilsa when her weight loss story blew up online."
After Ilsa's heard of Cara's story of being addicted to food, Ilsa couldn't help but to relate to her. "She said that she knows exactly what I've been through - and decided to helped me."
"Everybody thought that it was through the traditional diet and exercise; it was far from it."
