Use olive, sunflower, or canola oils instead of traditional animal or vegetable oils. There are foods that take the body longer to metabolize. In other words, the body literally works harder to break these foods down and therefore burns more fat calories. These are appropriately called fat-burning foods. When they are introduced to recipes, the result is to lower the overall fat calories that are absorbed by the body.
Examples are celery, strawberry, oats, wheat, apple, broccoli, spinach, and tomato.
For example, chop up celery in your favorite casserole or add a layer of spinach in the meatloaf before you roll it into the pan. Add peas to the tuna casserole and beans to your chili or soup. Beans are great fat-burners. Peppers and mustard are two ingredients that speed up metabolism in digestion. Add fiber to recipes.
