Did you know that there are more than 10,000 different types of protein throughout the body?
Amazingly enough, it's true, and these proteins can be found almost everywhere in and on the body, including the hair, skin, bones, tissues, organs and muscles.
Aside from gut health and metabolic health, protein is involved in a wide range of processes that generate energy, transport oxygen, make antibodies, keep cells healthy and control appetite.
Reducing Appetite and Excess Hunger
In fact, when looking at carbs, fat and protein, science has proven that protein is the most filling of these macronutrients; in other words protein helps you feel more full with less calories.
Part of the reason for this is that protein lowers the levels of the hunger hormone, ghrelin, and jacks up our levels of peptide-YY, which is a gut hormone that increases satiety, or feeling full.
Amino acids also curb appetite.
A 2017 study found that there’s a set of brain cells, called tanycytes, that control appetite, and that eating more of the amino acids lysine and arginine can flick off the hunger switch.
