So you want to lose weight? Well, don't use a low fat diet to try to do it. It will take you twice as long as a low carb diet. Why is this? Because healthy fats are necessary for your body, while fructose and grains in processed foods have a huge list of negative health effects. But you say that you need to prevent heart disease. Sugars - fructose and grains are the cause of this as well. More so than fats.

The key is the type of fats. No trans fats - margarines and vegetable oils. Here are the list of negatives for trans fats:

Cancer
Decreased immune function
Obesity
Diabetes
Problems with reproduction
Heart disease
