Hundreds of published studies have shown that diets high in saturated fats have been strongly associated with an increased risk of heart disease, and diets high in fruits, vegetables, whole grains and low-fat dairy products have been associated with a lower risk of heart disease. "Individuals who are trying to lose weight should consume a dietary pattern that has abundant scientific evidence behind it.

A reduced calorie diet rich in fruits, vegetables and whole grains, restricted in saturated fat and cholesterol can help individuals lose weight and lower their risk of cardiovascular disease. It is important to get at least 30, and preferably 60 minutes of aerobic activity, such as brisk walking daily. It's the long haul that really matters," says Eckel.
