If your focus is on specifically cutting calories from your meal plan to hit your goals faster, you may be considering slashing fat from your diet. That is probably the last thing you want to do. Not only have the benefits of a low-fat diet come into question in some recent research, the importance of healthy fats in your diet can’t be stressed enough. These beneficial fats have been shown to:
Leading the charge of the healthy fat brigade are avocados. This wonder fruit is essentially Mother Nature’s butter. It’s rich, creamy, and—unlike butter—an acceptable food to eat all on its own. While you should still limit yourself to a quarter or half of an avocado per meal, you have no reason to fear its fats. Avocados pack in healthy monounsaturated fats that contain oleic acid, which can actually help quiet feelings of hunger, according to a Food Function study. They also give you two things butter doesn’t: protein and fiber.

This little wonder food checks all the boxes. It’s an inexpensive food that’s packed with protein and a full amino acid profile. And contrary to decades of popular belief, eggs also don’t raise bad cholesterol levels. In fact, consuming eggs can actually lower cholesterol while improving heart health. (22) The choline found in eggs is also helpful at keeping our brains in tip-top shape. (23)
Of the three macronutrients, carbohydrates are our body’s preferred energy source because they are easier and quicker for our bodies to digest and use for energy. On the other hand, fat takes a different route before we can use it as energy because it is insoluble in our blood. Think of fat as being a reserve or our long-term source of energy that sticks around the longest. On the technical side, which we’re about to get very technical: fat is three fatty acids + a glycerol molecule, or a triglyceride (tri- as in three and glyceride).
Although for several decades the American Heart Association and other health organizations have advised people to reduce their saturated fat intake, studies have consistently failed to show a link between saturated fat and heart disease. Because of this, the role of natural saturated fats in a healthy diet is now being reconsidered. All in all, saturated fats appear to be neutral in their health effects.
One cup of black olives has 15 grams of fat, but again, it is mainly monounsaturated. Plus, no matter what variety of olive you enjoy, they all contain many other beneficial nutrients as well, such as hydroxytyrosol, a phytonutrient that has long been linked to cancer prevention. New research is showing that this phytonutrient may play a role in reducing bone loss as well. And if you have allergies or other inflammatory conditions, olives might be just the snack for you as research suggests that olive extracts function as anti-histamines on the cellular level. Even with all these benefits, it is important to be mindful of your serving size as olives can be high in sodium. Stick to 5 large or 10 small olives as the perfect portion.
Omega-3 fatty acids. One type of polyunsaturated fat is made up of mainly omega-3 fatty acids and may be especially beneficial to your heart. Omega-3, found in some types of fatty fish, appears to decrease the risk of coronary artery disease. There are plant sources of omega-3 fatty acids. However, it hasn't yet been determined whether replacements for fish oil — plant-based or krill — have the same health effects as omega-3 fatty acid from fish.
