6. Watch the type of fat you eat. Cut back on saturated fats, which are found in red meat, poultry fat, butter, cheese, milk, and coconut and palm oils, and keep trans fats, found in shortening and stick margarine, to a minimum. Replace trans fats with healthier polyunsaturated and monounsaturated fats. Examples of polyunsaturated fats include safflower, corn and soybean oils. Examples of monounsaturated fats include canola and olive oils. Although unsaturated fats are better for you in terms of cholesterol and triglyceride counts, they're high in calories, so go gentle on the amount you cook with or you may gain weight.
