It is hard to believe, but researchers have found that just four lifestyle factors play a role in a full one-third of all deaths.  Finding ways to avoid the impact of these four factors will help you live a longer and healthier life.

Factor One-Waist Size

The Western World is undergoing an obesity epidemic with the United States leading the pack and other Western nations gaining, literally, quickly.  There is a direct link between waist size, health and longevity.  The bottom line is that being overweight will increase your risk for heart disease, type 2 diabetes and even cancer.  Taking steps to lose weight will decrease your overall mortality risks and help you feel better in the process.  Here are a few of the key steps that will lead to weight loss.

1)    Eliminate junk food and processed foods
2)    Eat whole foods
3)    Increase fruits and vegetable intake
4)    Consume more omega-3 fatty acid rich foods such as sardines and wild Alaskan salmon
5)    Eat more nuts and seeds
6)    Choose lean proteins
7)    Dramatically reduce sugar consumption as sugar damages DNA

Following these basic tips above will increase your health and decrease your waist size.  There are bonuses to losing weight as well, such as increased energy and vitality.

Factor Two-A Lack of Physical Activity

Most people are not getting enough physical activity, and the effects are lethal.  Maintaining bones, ligaments, joints and muscles means that some form of resistance training is a must.  Likewise, your most important muscle, your heart, needs to be worked out as well.  In short, it is essential that you find a way to get your body moving a few times a week.

Factor Three-Smoking

There are few health decisions that anyone can make that are as detrimental as smoking.  Smoking has been proven to be extremely harmful to human health in hundreds of studies.  If you are smoking, it is in your best interest to take measures to stop.  Smoking dramatically increases the risk of cancer, and not just lung cancer, as smoking has been linked to a wide variety of cancers including that of the brain and pancreas.

Factor Four-A Poor Diet

Poor dietary choices will impact your health.  Likewise, it is very difficult, if not impossible, to lose weight and keep it off when one opts for an unhealthy diet.  Processed foods are, in short, a killer and they are reducing people's lifespan.  If you want to life longer and be healthier, you will need to choose a diet that is rich in vitamins and minerals.  Consider adding flavor to your food with spices which are full of not just taste but nutrition, immune boosting compounds and antioxidants.

A new you is possible, but it begins with a commitment to change your diet.  Taking the steps to eliminate junk food and processed food will lead to weight loss and increased energy.  Combine an overhaul of your diet with increased physical activity and you will see results.  Above all else, if you smoke, find a way to kick the habit.  The good new is that studies have shown that it is possible to undo some of the negative consequences of smoking once smokers quit.  Additionally, smokers who opt for an antioxidant rich diet will help their body undo some of the considerable damage that comes along with smoking.
