way too many people get freaked out about Thanksgiving they get freaked out about the holidays in general because they think that they’re eating all the wrong things well I’m gonna flip everything upside down here for you so that you can get through the holidays a little bit easier but also so we can clear up some of these myths I’m gonna give you some solutions and some tips and tricks that you can use to make it so that your Thanksgiving is a little bit easier and then you’re not buying in to the biggest things getting meal myth that’s out there so let’s talk first about this tryptophan link okay everyone seems to think that when you consume turkey that you’re taking in so much tryptophan that you get tired and that’s exactly why after we have Thanksgiving dinner we end up getting super sleepy and want to just veg out on the couch watching football that’s not quite the case but if we do understand how to trick the fan works it does help us out a little bit see what’s going on is when you consume tryptophan you’re consuming an amino acid that causes a chain reaction within the body you see what happens is tryptophan goes into the cell into the brain and therefore converts into serotonin which ultimately turns into melatonin in melatonin of course puts you to sleep but the thing is is that tryptophan cannot get into the brain unless insulin is present okay so tryptophan which of course is in Turkey isn’t going to actually make you sleepy unless it’s in conjunction with carbohydrates I’m not sure if you knew this or not but tryptophan is not all that high in Turkey in fact believe it or not there’s more tryptophan in nuts and more tryptophan and many seeds and even cheeses then there’s in Turkey so I don’t know where that started but I think that it has something to do with the fact they want us to consume more of the starchy carbs that are totally backed by all these different companies and by these different lobbyists and a little bit less of the meat and it just makes sense it’s kind of a natural progression that we’ve evolved in especially in America so if we look at how this process works that’s not why we’re getting sleepy so here’s the thing flip it on its head go ahead and consume a little bit more of the meat that you want to be consuming because it’s not going to make you tired in fact it’s only gonna benefit you and the cool thing I did want to talk about is butcher box sponsored this video and because it’s the holiday time butcher box is offering up some really special deals on all kinds of different meats so we’ve got hams we’ve got different kinds of beefs that you can use along with your Thanksgiving dinner or at least in the general vicinity of that same time line but also anyone that’s acting now is also gonna get free bacon for life with butcher box so I did want to make sure that I threw that out there so you don’t have to just be doing turkey you can be doing beef you can be doing whatever you want so check them out in the description down below so now let’s talk about what’s actually causing this situation okay the main thing is postprandial fatigue that is why you’re getting tired and it’s a pretty cut-and-dry simple thing you think carbs play the biggest role in the tryptophan uptake so like I said that tryptophan can’t get in to make you tired without the carbs well by and large by ratio generally with Thanksgiving we’re consuming like 70% carbs 20% protein and like 10 to 15% fat somewhere in there we’re actually not consuming a whole whole lot of fat depending on what kind of gravy you’re using most of us are eating the white meat chicken and then we’re having stuffing and then we’re having mashed potatoes we might put some butter on it but by far it’s a carb dominant meal okay you’re having this postprandial fatigue that’s happening from the tryptophan getting in and causing this issue how do you keep yourself in getting tired cut the cars down a little bit try to increase the fats a little bit even if you’re having some carbs to sell them out for fats trust me it’ll make life a lot better of course insulin obviously like I just started talking about insulin plays a big role so you’re consuming these carbs and then you have a big spike of insulin that insulins going to open the cell doorway so that the carbs can get in blood sugar just went up now the blood sugar is crashing so of course you have an issue but one thing that people don’t talk about a lot is something known as orexin okay orexin is a specific neurotransmitter and orexin plays a huge huge huge role in why you’re tired but also why the cravings can be so bad okay so if you can control the cravings that occur after Thanksgiving and I’m talking like subconscious neurotransmitter related traving so that you have your big Thanksgiving dinner then you go you sleep for a little bit while you watch some football and then you wake up and you’re not even hungry but for some reason something’s telling you you’re hungry so you have a bunch of pumpkin pie okay and then you’re like beyond full and it’s happening at a subconscious level and it all has to do with different neurotransmitters they’re almost putting you in for lack of a better term a hypnotic state so this erection neurotransmitter promotes wakefulness okay so without orexin we get tired and what happens is insulin inhibits this so insulin inhibits orexin so orexin which would normally allow you to be awake and feel alive and alert would make it so that of course you’re not feeling that you’re feeling tired and then again we have a double whammy effect insulin allowing all this to occur you just get tired but you also gain weight with it because then you’re suppressing your noradrenaline your adrenaline levels a good example would be if you have some coffee then you don’t feel as hungry because you have enough noradrenaline and adrenaline that’s riding you through it’s carrying you through you don’t have a desire to eat you don’t have these big ole undulations of blood sugar this without orexin you’re gonna have to deal with those issues so basically you’re killing off your adrenaline noradrenaline you just want to chill out and sleep so the other one we want to talk about is the circadian rhythm you see we’re eating at a terrible time when it comes down to Thanksgiving and I’m not telling to ruin Thanksgiving for you I’m just trying to give you some tips and tricks here and I’m helping you understand why okay we have a drop in our core body temperature that occurs towards the end of the day which is one of the reasons why we get tired that dropping poor body temperature again is voila what signals melatonin but we also have a small drop in core body temperature that occurs between 2:00 and 4:00 p.m. so it’s like starts up high starts well actually starts low comes up high midday and then starts to drop again but it takes a big drop in like 2:00 to 4:00 p.m. which is guess what right around when we’re having Thanksgiving so what you might want to start doing is doing some things to elevate your core body temperature a little bit before you have your Thanksgiving meal so a lot of people will try to starve themselves throughout the course of the day they’ll almost do like a variation of intermittent fasting in an improper sense so I know so many people that have like a small breakfast and maybe just eat a little bit of snack and then they’re say I’m not going to eat because I’m gonna have Thanksgiving dinner that’s one of the worst things that you can do okay you need to either cut and dry like intermittent fast before you go into Thanksgiving dinner or better yet intermittent fast start you’re fast the night before or maybe a little bit earlier like 7 p.m. or so ok then fast all the way until like maybe 1 p.m. and then eat something eat some protein so you get your core body temperature up ok eat some good amounts of protein use that butcher box that I talked about like capitalize on that get some good inexpensive meat that’s high-quality get your core body temperature up then you’re not gonna have to deal with that drop so not only is your metabolism going to be slightly elevated after a fast but you’re gonna have the thermic effect of food that’s working to your advantage then when it comes down to consuming your actual Thanksgiving meal you’re not also going to town you’re in a lot more control see it’s all being calculated eat a little bit of protein maybe a little bit of fat then go into Thanksgiving your family might look at you and say why are you eating you’re about to have Thanksgiving dinner but just tell them you know what you’re doing and tell them that Thomas told you so here it is the big Thanksgiving myth and this doesn’t just apply for Thanksgiving it’s gonna apply for Christmas it’s gonna apply for all kinds of other holiday meals that you’re gonna encounter and the trick will always remain fast break the fast then the meal it gives you a little bit more flexibility it allows the insulin levels to come back to normal a little bit so you don’t have the insulin sensitivity that gives you a big spike it just makes it happen and it makes it easy so as always make sure you’re getting it locked in here on my channel if you’re digging videos like this they’ll give you some more tactical things that you can do around the holidays or specific meals make sure you let me know and always make sure you shout a big THANK YOU to butcher box and give them a shot down in the description below I’ll see you in the next video

Popular Food Myths Debunked: Thanksgiving Food Coma- Thomas DeLauer…
So the myth is that turkey has a lot of a chemical known as tryptophan – it’s an amino acid that is a precursor for the brain chemicals serotonin and melatonin

But there is no more tryptophan in turkey than in other common meats like chicken and beef – other foods, including nuts and cheeses, contain more

So people think that when you have a lot of turkey that makes you tired because of all the tryptophan that you’re eating gets produced into serotonin and melatonin and then it makes us fall asleep

Serotonin gets converted to melatonin in the pineal gland and melatonin is responsible for regulating your sleep and wake cycle

The Truth:
That’s actually not true, the reason why we tend to be tired after we have a large meal at Thanksgiving is simply because of the amount of food that we’re having we have what’s called postprandial fatigue (postprandial somnolence), which is basically after you’ve had a big meal your body goes into shutdown mode and sleep gets promoted

Reasons for Postprandial Fatigue:
Thanksgiving meals are typically heavy in carbs, which help transport tryptophan across the blood brain barrier – so tryptophan could play a role in that sense, but the main reason is largely due to blood sugar spikes

Carbs & Insulin:
Simple carbs, such as cane sugar and high-fructose corn syrup, cause your blood sugar to spike up more rapidly than slower-moving complex carbohydrates, prevalent in starchy vegetables and whole grains

The rapid spike from eating simple carbs, particularly in excess or without other foods, can cause your blood sugar to plummet back down, leading to that groggy crashing feeling

And with Thanksgiving, the larger the meal, and the more carbs and proteins it contains, the higher the blood sugar spikes – more insulin is produced as a result

This, however, is not limited to sugar – many of these insulin receptors are in the hypothalamus, a region of the brain controlling various aspects of the nervous and endocrine systems

Orexin, a neurotransmitter produced by specialized neurons, is believed to be a stimulant that promotes wakefulness

As it happens, orexin neurons in the hypothalamus are inhibited by insulin – the bigger the meal, the more glucose there is in the blood, more insulin is produced, which reduces the production of orexin, and lethargy ensues

At the same time, insulin also exerts positive control over sleep in the hypothalamus by stimulating production of the Melanin Concentrating Hormone (MCH)

MCH, like orexin, also helps to regulate sleep and wakefulness, but unlike orexin, MCH promotes sleepiness

In sum, a large meal induces sleepiness from two directions, by stimulating processes that encourage sleep (MCH) and reducing those that encourage wakefulness (orexin)

Sleepiness after a Thanksgiving meal can also be down to our body’s circadian rhythm

Explains the natural biological clock that induces sleep at 2:00 AM to 4:00 AM and again between 2:00 PM and 4:00 PM in the case of adults

It has to do with a dip in your core body temperature – right before you go to sleep at night, your core temperature begins to drop, which is a signal to the brain to release melatonin

The exact same thing happens on a smaller scale between 2 and 4 in the afternoon – it’s a mini-signal to your brain to get sleepy
