It is a widely accepted and repeated notion that one cannot lose weight would exercise for sometime every day.

But the story of a BC woman, Francina Kehoe, who lived with, and fought, obesity for years on end, seems to highlight that some researchers might just be right - more than exercising, what matters is what one eats.

On February 8, surgeons put Francina under the knife and removed as much as 85% of her stomach.

For five years, the woman waited to get a vertical gastric sleeve gastrectomy, a type of weight-loss surgery that works by shrinking the stomach from the shape of sack to a thin tube. About 6 hours after her first surgery, Francina underwent a second one to stop internal bleeding. She battled with blood transfusion, an increased heart rate and swelling in her hands and arms, among other problems.

Despite the fact that the lady weighed an astonishing 310 pounds at her heaviest, she could easily ski or walk as much as 10 kilometers. She exercised regularly, hitting the gym for about three to four times a week for months on end, but her weight never went down.

The case has managed to intensify the ongoing debate of what helps weight loss more. While some swear by exercising, some other feels that it is all about what one eats.
