Does Fat Make You Fat? Essential Facts About Healthy Fats

We’ve been asked this question so many times: Does fat make you fat? The one-word answer is “no.” However, many people avoid fat or believe it causes weight gain. This misconception likely stems from the low-fat craze of the ‘90s diet industry.

It doesn’t help that both body fat and dietary fat share the same name, leading to the belief that “you are what you eat.” Additionally, the term “fat” is often used to describe someone who is overweight. Combined, these factors contribute to the widespread avoidance of fat and the popularity of “low-fat” and “fat-free” products.

Understanding Dietary Fat

Many people mistakenly believe that eating fat leads to weight gain. This confusion often stems from the diet industry’s emphasis on low-fat foods in the past. However, dietary fat plays a crucial role in our overall health and well-being. To understand its importance, we need to look at the different types of fat and how they affect our bodies.

The Importance of Fat

Dietary fat is not a problem; it is one of three essential macronutrients, along with protein and carbohydrates. Fat supplies energy and provides essential fatty acids that the body cannot produce. According to “The Essentials of Essential Fatty Acids” published in the Journal of Dietary Supplements, “Studies have shown that increasing the intake of certain essential fatty acids can enhance health, aid in treating diseases, and improve body composition, mental, and physical performance.”

Types of Fat

Not all fats are created equal. Here, we break down the three main categories of fats: unsaturated, saturated, and trans fats.

Good Fats: Unsaturated Fats

Unsaturated fats, often called “good” fats, are beneficial for your health. These fats are found in foods like fish, nuts, and avocados. They help improve heart health and provide essential nutrients.

Controversial Fats: Saturated Fats

Saturated fats are found in meat, dairy, and some plant sources. Experts have varying opinions on saturated fats. A reasonable amount of high-quality saturated fat can be part of a healthy diet, but excessive consumption, particularly from high-calorie fast foods, often lead to health issues.

Bad Fats: Trans Fats

Trans fats are primarily found in processed foods and are linked to heart disease, strokes, and other health problems. These fats should be avoided to maintain good health.

What Actually Causes Weight Gain?

If dietary fat isn’t the culprit, what causes people to gain body fat?

Researchers increasingly point to refined carbohydrates and sugar. Many foods packed with both sugar and fat are delicious, making it easy to overconsume them. Overconsumption of fat adds many calories to your diet. It’s not the fat itself that’s bad, but the quantity consumed.

Sugar, despite having fewer calories per gram than fat, disrupts hormones like insulin, contributing to weight gain. High levels of added sugar are harmful to health and can complicate weight management.


Body fat is not directly produced by eating dietary fat. Healthy fats are an essential part of a balanced diet. Weight gain is more closely tied to factors like food quantity, quality, activity levels, and other lifestyle choices.

Including foods like almonds or avocado in your diet provide energy and support your workouts. However, consuming large quantities of chips, chocolate bars, and double-cheeseburgers regularly won’t help you achieve your fitness and health goals.
