In recent years, the demonization of fat has been widespread in the health and wellness community. While some types of fat can be harmful if consumed in excess, the idea that all fats are bad for you is a gross oversimplification that misses the complexity of the human body. In fact, many types of fats play important roles in maintaining overall health and well-being, and cutting them out of your diet entirely can actually be detrimental to your health.

The Different Types of Fat: A Primer

Not all fats are created equal. There are four main types of dietary fats: monounsaturated, polyunsaturated, saturated, and trans fats.

Monounsaturated and polyunsaturated fats are considered healthy fats and are an important part of a balanced diet. These fats can help lower your cholesterol, reduce inflammation, and improve heart health. Good dietary sources of these fats include nuts, seeds, seafood, and vegetable oils like olive oil or canola oil.


Saturated fats are generally considered unhealthy and can contribute to high cholesterol levels, heart disease, and stroke. These fats are commonly found in animal products such as meat, butter, and cheese. While it’s generally a good idea to limit your intake of saturated fats, it’s worth noting that not all sources of saturated fat are created equal. In fact, recent research suggests that certain types of saturated fat, like those found in coconut oil, may have health benefits when consumed in moderation.

Trans fats are considered the worst type of dietary fat, as they have been linked to an increased risk of heart disease, diabetes, and other health problems. These fats are commonly found in processed foods like cookies, crackers, and fried foods. Trans fats should be avoided entirely.

The Benefits of Healthy Fats

One of the most important roles that healthy fats play in the human body is providing energy. Fats are more calorie-dense than carbohydrates or protein, meaning that they provide more sustained energy than their counterparts. Additionally, healthy fats play a crucial role in nutrient absorption. Many vitamins, such as vitamins A, D, E, and K, are fat-soluble, meaning they can only be absorbed by the body when consumed with fat.

Beyond these basic functions, healthy fats have been linked to a variety of health benefits. For example, a diet high in monounsaturated fats has been linked to lower rates of heart disease, while a diet high in omega-3 fatty acids has been shown to reduce inflammation and improve brain health.

Why Cutting Out All Fats is a Bad Idea

Despite the benefits of healthy fats, many people continue to cut them out of their diets entirely in an effort to lose weight or improve their health. Unfortunately, this strategy is unlikely to be effective, and can actually be harmful in the long run.

For one, cutting out all fats can lead to nutrient deficiencies. As mentioned earlier, many vitamins are fat-soluble, meaning that you need to consume fat in order to absorb them. Additionally, fats are necessary for the production of certain hormones and cell membranes, and cutting them out entirely can lead to a variety of health problems.

Perhaps most importantly, limiting fat intake can often lead to overconsumption of other foods, particularly carbohydrates. Carbohydrates are a quick source of energy, but they are not as filling or satiating as fats or protein. As a result, people who cut out fat often end up eating more carbohydrates than they would otherwise, which can lead to weight gain and other health problems in the long run.

In Conclusion: The Importance of a Balanced Diet

The truth about fat is more complex than the common sentiment that all fat is bad for you. While there are certainly types of fat that should be limited or avoided, healthy fats are an important part of a balanced diet and provide a variety of health benefits. Rather than cutting out fats entirely, it’s best to focus on consuming a balanced diet that includes a variety of healthy fats, carbohydrates, and protein.
