Have a Healthy Bodyweight

One of the leading causes of obesity is obesity or simply being slightly overweight. In fact, the more overweight a person is, the more likely they are to come down with type 2 diabetes over the course of their lifetime. Get on a scale and weigh yourself, and then use a BMI (Body Mass Index) calculator to determine where your weight falls: underweight, healthy, overweight, or obese. Adjust accordingly and pursue a healthy bodyweight that will help fight off the onset of type 2 diabetes.

Recent studies have shown that losing even ten or twenty pounds can dramatically decrease the likelihood that someone will suffer from the onset of type 2 diabetes. This is an easy weight loss goal that will take between 3 and 4 months, but will result in a lifetime free of this disease.

Eat Healthy Foods

Again, this is something that everyone should do regardless of the onset of diabetes. A balanced diet that includes fruits, vegetables, whole grains, and and lean meats has been shown to reduce the incidence of diabetes. As well, limiting intake of saturated fats and trans fats also reduces the risk that diabetes will affect an individual. And those looking to prevent type 2 diabetes should limit their intake of sugary soft drinks and juices -- not only to limit the sugars themselves, but to prevent insulin-spiked hunger, excessive calorie consumption, and weight gain that can lead to the onset of the disease.

Limit Alcohol Consumption

Frequently drinking alcohol -- whether it's a few beers or a binge drinking night out on the town -- exposes people to a greater risk of developing type 2 diabetes. That's because these drinks have high carbohydrate levels that spike the level of insulin in the blood, just like eating a large bowl of pasta or drinking a large glass of soda. Frequently drinking alcohol is one of the leading causes of type 2 diabetes and it is perhaps the easiest thing to change immediately in the interest of preventing the disease.

Eat Less, But More Frequently

Instead of eating three larger meals throughout the day, break up your meals into six smaller meals that span the course of a day from breakfast to a post-dinner snack. This encourages a healthy level of calorie consumption and maintains your blood sugar and insulin levels at a healthy amount throughout the day, rather than encouraging three peaks and and valleys as a big meal approaches and is then finished. One of the best ways to prevent type 2 diabetes is by working with your blood sugar levels, rather than against them -- and that means equilibrium throughout the day.
