The guy was tired and hungry and was thinking of food
An authentic latin taco
is a high fat, high carb, high fiber, high protein, high flavor, high nutrition food
One of the best things for stress is fat+carbs+protein
For women chocolate, ice cream
For men - guys go for stuff with a higher hit of tryptophan -pizza with its higher milk solid content + bacon + some type of meat, will have more protein than say... ice cream or milk chocolate.
I've never seen anyone with falling blood sugar levels (some one who is tired / tiring) crave a low carb, low fat snack or talking or thinking out loud about having something like a salad (or something that goes in a salad) - The human body (and mind) just doesn't work like that.
Personally When I'm really hungry and have had a long day I want a kebob and a high sugar - none of that diet stuff - soda and some fries - and maybe a burger - but it has to be a large chicken filet burger
thats how I like my fat+sugar+protein
other times this old classic works for me:
peanut butter+jelly on bread+ full fat milk
trptophan-packed with polyunsaturated fat + carbs, glucose, fructose + lactose, saturated fat and more tryptophan
If you see / or hear a person taling about a food - when no one's asked them to talk about food - and that food is a high fat, high carb, high protein food, that person is hungry and that person is under stress.
