The thought of fat accumulating in the body drives people with lipophobia into a state of unbelievable fear, which can lead them to have very restrictive, and often destructive, diets and eating habits to avoid fats in foods. This is not a common fear, and documented cases of lipophobia have only begun in the last four decades.
