why does our body appear to be so lathargic after a large meal?

There's a hormone called insulin which is secreted by the pancreas which helps decrease your glucose (blood sugar) levels.  After a large meal, there is a huge spike in post-meal insulin response which overcompensates and produces more insulin than is necessary to quickly lower blood glucose.  This in itself can make you feel tired and hungry again.  At the same time another hormone is released called cholecystokinin. One of the functions of this hormone is to make you feel full. But it also activates the areas in the brain involved in sleep.  Finally, the level of an amino acid called "tryptophan" increases, it is converted into "serotonin" in the brain. Serotonin also does a very good job of making you feel sleepy!\n\nBest advice:  Eat more frequently and eat smaller meals to avoid this effect.

My husband doesn't have either. He is just full of energy. For instance, when he is sitting on the recliner watching tv he is unaware but he swings his feet back and forth sometimes for almost an hour before he settles down.  Then he wonders why his legs feel sore. \n\nOne thing I have noticed in him and other people I have encountered in the business world is that the hyper people seem to only eat one big meal a day. I asked why and one person told me that to eat a large meal slows him down so he only eats a large meal at night.

A lot has to do with fluctuations in your blood sugar levels after eating lunch.

I've noticed it too.  Also, the longer it's been since you've eaten a certain food, the better it tastes.  There are some dishes I only cook in the summer, and my first taste every year is heaven.  \nIt might be psychological--that it was worth the wait.  Or it might be that we've forgotten how it tastes.  Or maybe when we're hungry our sense of smell and taste is heightened.\nGood question.  I get tired of answering "how can I lose weight" over and over. :)

It's not the number of meals you eat,but more likely to be the content of the food. Especially sodium(salt) which in women tends to make them retain water and feel or look blotted. More so if it close to the time of your period. So don't skip meals my dear, that will slow your metabalism, which will lead to weight gain. Maybe just watch your salt intake, drink lots of water and maybe if needed get a water pill. G'luck

Metabolism peaks in the morning hours after being deprived of food for hours.  Even though the metabolism is slower in the sleep hours it has been digesting and you have been getting hungry. Our metabolism begins to speed up as we awaken.  After you have eaten in the morning, it is quite likely that your metabolism has sped up even more with the introduction of food for energy. This could be a prime work out time for you!  \nOther possibilities, if you ate a HUGE meal the night before, there is theory that it stretches your stomach and when you wake up the next morning it feels hungrier because it is stretched.  The other thing may be that when you eat your morning meal, you eat too quickly and your brain needs time to catch up to the full feeling! \nSomething to think about!

Could be a lot of things.  They say it takes the stomach 20 minutes to realize it's full and tell the brain "okay stop eating"  so try making each meal last at least 20 minutes (eat slower)\n\nYou could be eating a lot of sugars or carbs that burn a lot faster then proteins so you feel hungry more often.\n\nStrange thing about the stomach.  It's like a balloon.  The more you eat the more stretched out it becomes.  The less you eat the smaller it becomes and then it doesn't take as much food to fill it.  The Gastric Bypass surgery works on this principal.

It is a metabolic product which ultimately derives from glucose. You may have had some high sugar food stuffs. Then again there is the occasional error.

Sometimes when you get ill after eating something, it wasn't necessarily bad food.  You may have had a touch of stomach flu beforehand and the overeating could have just exacerbated the symptoms.\nRemember that the holidays are notorious for rich foods.  I went through 5 pounds of butter making dinner for today..that type of food could upset anyone with a queasy stomach.

It's not good because then your body begins to use it's fat for energy...and when you start eating again it will cause you to gain more weight than before.

Sounds like you already know what could be causing this: diabetes.\nHowever, it could always be conincidence. Maybe you're tired or stressed, and you only have a free moment to notice when you sit down to eat.

It's messing up your metabolism.  Your body needs its nutrients at specific times because it's still growing.  If you eat at odd times that are spaced out your body won't know how to adjust its metabolism to what's appropriate for you.

yeah but for me its some weird reason... when i'm in school my appitite just disappears... when I go and eat (I only eat a hashbrown cause my stomach isn't HUNGRY at all!!!) and then I feel like throwing it up =( .. then i'll buy a fruit juice to wash it down... not sure why but I think it depends on the mood o.O ... i'm no doctor but that's my hypothesis.

This might be because, you are eating until you are to full. Try not eating so much. You might need to see a dr. My daughter has to take medicine because, sometimes she feels sick after eating. I'm sorry but, I forgot the name of the medicine but, it is a prescription.

Because you're super thin, and your body has digested the food overnight and it's moved.  Also when you lay down gravity is pulling at your body differently than when you're standing up.  It's pulling more firmly from every direction, when you're standing, it's just pulling you down.  \n\nDon't worry.  It's normal to be "skinnier" when you get up -- your body's had hours upon hours to digest food and revamp it's cells.
