It's a start.

1. To know exactly how many calories you eat a day and how much you could burn up.

2. Variety of food groups a day. Vegetables & fruits! Eat fish at least twice a week. "Recent research shows that eating oily fish containing omega-3 fatty acids (for example, salmon, trout, and herring) may help lower your risk of death from coronary artery disease."

3. From the American Heart's site (Also, the two above):

Choose lean meats and poultry without skin and prepare them without added saturated and trans fat.

Select fat-free, 1 percent fat, and low-fat dairy products.

Cut back on foods containing partially hydrogenated vegetable oils to reduce trans fat in your diet.

Cut back on foods high in dietary cholesterol. Aim to eat less than 300 milligrams of cholesterol each day.

Cut back on beverages and foods with added sugars.

Choose and prepare foods with little or no salt. Aim to eat less than 2,300 milligrams of sodium per day.

If you drink alcohol, drink in moderation. That means one drink per day if you’re a woman and two drinks per day if you’re a man.
