Four simple healthy lifestyle factors account for reducing chronic disease risk: not smoking, not being obese, getting a half hour of daily exercise, and eating healthier, defined as consuming more fruits, veggies, and whole grains, and less meat. Following a Food and Behaviour Plan personalised, adapted to your characteristics and personal needs, you may be able to wipe out more than 90 percent of your risk of developing diabetes, more than 80 percent of your risk of having a heart attack, cut by half your risk of having a stroke, and reduce your overall cancer risk by more than one-third. For some cancers, like colon cancer, up to 71 percent of cases are preventable through diet and lifestyle changes.
