Two important types of fat in the body are white fat and brown fat. White fat is located in the chest, abdomen, and upper legs; too much of it constitutes obesity. Its function is to provide insulation against the cold, store fats derived from food, and continually release small amounts of the fats to be converted into energy. Brown fat is found in small amounts in the neck, shoulders, chest, and abdomen. Its main function is to burn the fat it stores, creating heat that keeps the body warm.

Cheese is often eaten with less-healthy foods such as refined grains and meat, including pizza, burgers, mac and cheese, and Mexican food.
