Eating foods with fat is definitely part of a healthy diet. Just remember to choose foods that provide good fats (monounsaturated and polyunsaturated fats) and balance the amount of calories you eat from all foods with the amount of calories you burn. Aim to eat a dietary pattern that emphasizes intake of vegetables, fruits, and whole grains; includes low-fat dairy products, poultry, fish, legumes, non-tropical vegetable oils and nuts; and limits intake of sodium, sweets, sugar sweetened beverages and red meats. Doing so means that your diet will be low in both saturated fats and trans fats.
Monounsaturated fats are typically liquid at room temperature but solidify if refrigerated. These heart-healthy fats are typically a good source of the antioxidant vitamin E, a nutrient often lacking in American diets. They can be found in olives; avocados; hazelnuts; almonds; Brazil nuts; cashews; sesame seeds; pumpkin seeds; and olive, canola, and peanut oils.
From time to time, try swapping other meats for a serving of fatty fish that is high in protein and Omega-3s. Popular types of fatty fish include salmon, anchovies, Chilean sea bass, mackerel, and sardines. Those who consumed this type of fish regularly were found to have less of a risk for a heart attack, according to a study in the American Journal of Clinical Nutrition. Warren adds that consuming fatty fish has also been linked to an improved mental ability and may help prevent cancer.
Meanwhile, the official unsaturated fat definition encompasses any type of fatty acid that contains at least one double bond within the chain. These fats are further classified as either a monounsaturated fat or polyunsaturated fat based on the number of double bonds they contain. Unsaturated fats can include foods like vegetable oils, nuts, seeds and fish.
But even as important is their ability to reduce the negative impact of yet another essential type of fatty acid known as omega-6s. Found in foods such as eggs, poultry, cereals, vegetable oils, baked goods, and margarine, omega-6s are also considered essential. They support skin health, lower cholesterol, and help make our blood "sticky" so it is able to clot. But when omega-6s aren't balanced with sufficient amounts of omega-3s, problems can ensue.
CLA may also reduce the risk of heart disease, thanks to its high antioxidant levels and ability to lower bad cholesterol.

Remember, you are what you eat eats, so you want to choose the best quality possible. And when it comes to beef and healthy fats, grass-fed beef is definitely the winner.
Other studies have confirmed the health benefits of following a low-carb diet rather than a low-fat diet. In one study, women lost more weight following a low-carbohydrate diet than a low-fat diet (5). In addition to weight loss, studies also show that low-carb, high-fat diets reduce inflammation, regulate blood sugar levels, and reduce triglycerides while raising HDL cholesterol levels (6,7).
