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.

Processed foods are those that have been changed from their original form. A minimal level of processing may mean the food has simply been chopped and frozen or that inedible parts have been removed. At the next level, processed foods have a few added ingredients. Foods with even more processing are called "ultra-processed" foods. Ultra-processing usually means that the original foods are not recognizable, and include additives such as preservatives, oil, sugar, salt, coloring, and flavoring. If there are more than a few ingredients listed on a food label, that food is probably ultra-processed, which is bad for health.
