It's a common form of the disease, but some patients with Type 2 diabetes can go years without being diagnosed because they don't have symptoms.
That's where exercise, like cycling, comes in. Aerobic activity prompts insulin to do what it's supposed to: absorb glucose into the body's cells.
The American Diabetes Association recommends 150 minutes of moderate-to-vigorous aerobic exercise a week, which breaks down to 30 minutes, five days a week.
A lot falls under aerobic exercise. Researchers at Harvard University found walking briskly for just a half hour each day can cut the risk of developing Type 2 diabetes by 30 percent.
The researchers said they studied cycling because unlike some other aerobic activities, like dancing or rowing, it "can be included in everyday activities," like biking to work.
They also found the participants who took up cycling only after the study started lowered their risk of developing Type 2 diabetes compared to those who didn't cycle at all.
