According to a new study besides helping lose weight, consuming a ketogenic diet which is high fat, low protein and low carbohydrates can also help maintain vision in patients with glaucoma.

Glaucoma is a progressive disease in which damage to the cells that transmit visual information to the brain leads to vision loss and, in some cases, blindness.

Higher rates of glaucoma in people with diabetes suggests a potential connection between this eye disease and metabolic stress.

The findings led by Denise Inman from the Northeast Ohio Medical University in the US showed that low carb, high fat diet protects retina cells and their connections to the brain from degeneration.
