4. Eat healthy fats

Fatty foods are high in calories and should be eaten in moderation. To help lose and manage weight, your diet should include a variety of foods with unsaturated fats, sometimes called "good fats."

Unsaturated fats — both monounsaturated and polyunsaturated fats — promote healthy blood cholesterol levels and good heart and vascular health. Sources of good fats include:

• Olive, sunflower, safflower, cottonseed and canola oils
• Nuts and seeds, such as almonds, peanuts, flaxseed and pumpkin seeds
• Fatty fish, such as salmon, mackerel, sardines, tuna and cod

Saturated fats, the "bad fats," are found in dairy products and meats. These should be a small part of your diet. You can limit saturated fats by eating low-fat dairy products and lean chicken and pork.
