Walking lowers your risk for diabetes
According to researchers in Australia, the more you walk, the less you are prone to diabetes.

The experts monitored 592 adults in an attempt to map the occurrence of diabetes in Australia from 2000 through 2005. The subjects went through a health evaluation before the start of the study and also gave certain details about their eating habits and lifestyle. They were also issued pedometers and given instructions on how they will use them.
After five years, a follow up was done and the results showed that those with higher step counts also had lower ratio of the waist and hip and also had better sensitivity to insulin.
Comparing the insulin sensitivity, they found out that those who walked about 10,000 steps per day is 3 times more sensitive to insulin compared to those who walked 3,000 steps per day, 5 times every week.
The study concluded that higher levels of physical activity to better BMI or body mass index, waist-hip ratio, and sensitivity to insulin.
The current recommendation is to have at least 3,000 steps a day for at least five days per week.
