Egg composition may vary slightly, but on average the macronutrient content of one egg is low in carbohydrates and high in proteins and lipids2. High protein foods, like eggs, have been known to have a high satiety effect and be long term appetite suppresants4. Appetite is defined as a strong desire to satisfy a bodily need. The regulation of appetite is a combination of peripheral signals with the central nervous system, mainly the hypothalamus1. Ghrelin and leptin are two hormones that aid in appetite stimulation and appetite inhibition, respectively. When someone is hungry, their ghrelin levels will be high. This hunger signal is created once ghrelin is released into the bloodstream by the stomach. It crosses the blood brain barrier and binds receptors to the hypothalamus which signals hunger. Once the protein is eaten, it will travel through the mouth and into the stomach and small intestine. Here is where leptin will begin to be released to suppress appetite.
