Low-fat diets are one of the most popular fad diets, along with low-carb diets. Essentially, low-fat diets aim to restrict fats, particularly saturated fat and cholesterol. Low-fat diets have become fads because they are purported to reduce obesity, heart disease, and many other maladies.

Regardless of their popularity, low-fat diets have little evidence to support their usefulness in improving health. Some studies have even found them to reduce levels of testosterone. The faddish nature of low-fat diets has been obliquely referred to by high-profile scientific journals, such as one which referred to low-fat diet as an "ideology".
