You know spinach, soy, eggs and many other foods have the same "sleepy" ingredient in similar numbers as turkey? It's not the turkey, it's that you (not you personally) ate a shitload of food and your body is trying to say, SLOW DOWN FELLA we need to digest, stop eating. Fat fuckers just ignore that and eat more. Sleep. Wake up and eat a fucking whole pie. Ruining football by snoring.  If you burnt a shit ton of calories and your body was like "food in my face NOW" a burger and fries or whatever you fancy is going to get you through the day. You don't have to eat raw, all natural, organic, quinoa, with the dew of fairy, and no animals were harmed, kale. If that's your bag, cool. But most people who don't like vegetables is probably (paper theories not laws but supported) because their biological response is "this food has high water, low caloric value, and taste bitter which is an indicator that it may be a non food" VS something fatty/savory/salty means "this certainly has dense calories, I can absorb it quickly and it will provide energy". Just don't eat like a pig and you won't look like one. The downfall of society is the overabundance of food, too much free time, and we basically can obtain food whenever, wherever, however, with almost zero effort.
