A protein rich diet may make us more alert and help us lose weight.
The reaction of Hypothalamic orexin/hypocretin neurons to amino acids (especially nonessential amino acids) appears to be a mechanism for this effect.
Poultry products appear to be one of the better ways to get nonessential amino acids.
I’ve been trying to increase the protein in my diet for the past four months (in response to weaker evidence than I’ve linked to here), and have found that animal sources have been the easiest way to do that (I’ve mainly increased my egg and meat consumption). I think I’ve found it slightly easier to avoid gaining weight. I think I’ve also been more alert, but I don’t think the increase in alertness coincided too closely with the increase in protein consumption.
Note poultry is high in omega 6, so if you eat it, make sure you get lots of omega 3 elsewhere
The top protein foods almost always come from meat. As a vegetarian I have been aware of this and have found some brilliant vegetarian protein sources that will easily help you consume all the ammo acids. One brilliant ingredient to look for is hemp seed protein. Hemp seed is an nutritious nutritional supply of easily digestible gluten-free protein. All beans, lentils, and peas are also a excellent vegetarian and vegan source of protein as well. Of course you have all those meat substitutes also, these are not to everyone’s liking though.
