why should we feel sleepy after having LUNCH or DINNER?

You shouldnt but you might because your body is busy digesting and sorting out good and bad, etc.  You may feel sleepy but check out how heavy the food is or how much your eating.  Food is supposed to give you energy not a need for nap (unless it is turkey and that is b/c of a chemical in it).

Your body is trying to tell you that it needs a rest or it just needs food into your system because it is not getting enough oxygen to the brain. The best thing to do is to take a nap but, if you don't have time get something good to eat or something cold to drink.

Sometimes it can be what you are eating that can make you feel tired.  Sugar and processed foods can do that.  You should do about 4 days cardio and 2-3 days weights.  Do weights after cardio and make sure you take a high quality protein shake after your workouts to help rebuid your muscle.  I lost 54 lbs and got in great shape!  Check out my before and after pic here http://www.healthandstrength.net\n\nHere is what I did, you can use these ideas, they are what helped me make the change you see in my picture\n1. NEVER EVER ate sugar. It's a poison that makes us older, sicker, fatter and tired...all things we dont want. Seriously, sugar is the one who does the dirty work in weight gain. Stop eating it all together. You can see my list of ingredients to avoid when shopping here http://www.healthandstrength.net/qofweeka.htm...\n2. Drink ALOT of water. 2-3 liters a day. The more the merrier!  We need about half our body weight in ounces JUST for regular body functions!  When you feel thirsty, that means you are already dehydrated and lose brain function.  Water flushes toxins from your fat cells and keeps you younger.\n3. Exercise!!! So very important. Here http://www.healthandstrength.net/abexe.htm... are my favorite ab exercises.  I also do cardio 4-5 days a week for about 30 minutes a time.\n4. Eat less. How many calories do you think is in that burger or that plate of fries or in that handful of chips. What about overfilling our plates? If you go here http://www.healthandstrength.net/qofweek.htm... I wrote something about saving on calories and losing weight.\n5. Go to sleep before 10pm. Your body starts repairing and rebuilding and speeding up weight loss while you sleep only if you sleep at about 10pm. If you are awake and go to bed at 12, you miss out on that very important time. I have a good article on my site here http://www.healthandstrength.net/qofweekb.htm that talks about the importance of sleep and how STRESS can make actually make you fatter.\n6. BE POSITIVE. Be thankful every day and love yourself\n7. BE CONSISTANT! That I think is the KEY to losing weight. So what if you went a week and only lost a pound...or didnt lose any...KEEP going. DON'T stop. This is a lifelong commitment, so stick to it and one day you will open your eyes and need a new wardrobe!\n8. Eat more veggies and skinny friendly foods. I have my list of my top ten foods that I ate to lost weight here http://www.healthandstrength.net/tenfoods.htm...\n80% veggies at every meal including breakfast will keep you young and help you lose weight. \n9. Do the little things that count!  Check out 10 cool ideas that you can do to help boost your calorie burn throught the day here: 1. NEVER EVER ate sugar.

Milk is filled with an amino acid called l-tryptophan.  It commonly makes you sleepy.  (Turkey also has alot of l-tryptophan. . .that's why American's tend to feel sleepy after Thanksgiving dinner.)

I HAVE THIS SAME PROBLEM. it really sucks...it seems like i try to do something else and it just doesn't work...then after you eat, you feel even worse. what works for me now though, is  i eat something healthy, like a bowl chicken noodle soup, or a salad with chicken in it.

Sleep, and eating protein-rich food.

Its the same thing as if you were to eat a very large dinner (think back to how you felt after last Thanksgiving) your body is using up so much of its energy digesting that you feel physically tired. Try using water instead of milk, or if that tastes too bad just less milk. You are taking in too many calories for your body to handle it all.

I've never read anything drawing a direct link between dinner and mood the following morning, however if you're eating that late at night you aren't getting the ideal 7-8 hours sleep per night, which will definitely affect mood.  Diet does affect sleep patterns, which in turn affect mood, so if you're eating that late stick to light meals with only whole-grain carbs and no red meat.  Eat your big meal at lunch.

Assuming the total number of calories, and the general distribution of necessary nutrients is the same, I think many small meals is easier on your digestion, and gives you less of the ups and downs of blood sugar and protein to the brain than two or three large meals.  Ever notice how people tend to fall asleep after a large meal?  That's because the blood is diverted from the brain to the digestive system, leaving them stupid and sleepy.

1.  Frequent headaches - see your doctor, there could be an underlying problem you can't see.\n\n2.  When do you work out?  Day time - excellent, but not after your last meal of the day.  When you exercise, you are working up your metabolism - and yes, exercise and a full day of activities can wear you out - this is why we sleep.\n\nIf you work out after your last meal of the day, you are over working your metabolism and it takes time for the body to wind down properly.\n\nBeing tired, drowsy, fatigued does not make you "weak" just means you have worn yourself out.  This is good if you wish to live a normal life of excercise, activity, and eating a sensible diet.\n\nIf you are over drowsy, tired, fatigued, then you should seek advice from your doctor.  Taking vitamins and suppliments do not replace a proper sensible diet.\n\nDon't try to over do the excercise - this could lead to serious health issues that you will do more harm to your body too early - thus wearing out your interest in remaining in a healthy state of being.\n\nTry Yoga and meditating for calming yourself down, stretching your body's muscles properly and thus after your last meal of the day, you can relax as you should.  The human body can only do so much, and not more than it should/could.  Try getting to know your body, learn to like yourself and excercise appropriately at the right times of the day.  Rest when you should.

If, as you state, this seems to usually happen when you skip dinner, then it could be a result of a drop in your blood sugar. A drop in blood sugar can cause a multitude of problems and will eventually overstress your pancreas and adrenal glands, which is something that you definitely don't want.\n\nEat dinner (you need to finish eating a complete meal 2 1/2 to 3 hours for proper digestion to occur before you go to sleep) or at the least a snack (which can be consumed 45 minutes to 1 hour before bedtime) on a consistent basis and see if the problem goes away. You might want to try a good protein shake either as a meal substitue or the snack. \n\nIt's important to eat a very healthy diet throughout your life. It is especially crucial at present since you are still maturing. Your brain will not finish completely developing until the age of 21-22. It is essential that you get on the right track with a healthy diet NOW in order to not pay a steep price with your health at a later date. Basically, eat real food and avoid junk, processed food and, most importantly, sugar. \n\nThe other possibility--yes, as stated from others, you may be sleeping in a position that is affecting some of the nerves in your neck and arms. Make sure that you have a good pillow, that provides adequate support for your neck, and that your mattress has the correct firmness.\n\nIf the problem does not go away, see your doctor.\n\nGood luck and best of health.\n\nA Massage Therapist

Two popular theories atm...\n\nFirstly, Researchers have discovered that high blood glucose levels, similar to those after eating a big meal, can switch off the brain cells that normally keep us awake and alert. \n\nAlso, when you eat, lots of blood travels to the intestinal area to carry nutrients around the body. This is known as shunting. When this occurs, your brain is getting less oxygen. \n\nThe first theory is the more credible, with the second theory being the best applied to why you feel cold after eating (less blood to extremities).

1.it may be because of gastric problem\n2.it is because your stomach secretes hydrochloric acid and other digestive enzymes when u feel hungry

Why we need a siesta after dinner\n15:42 05 June 2006 \nNewScientist.com news service \nLinda Geddes\n\nThe mystery of why we often feel sleepy after eating a big meal may finally have been resolved. Researchers have discovered that high blood glucose levels, similar to those after eating a big meal, can switch off the brain cells that normally keep us awake and alert. \n\nThe findings make evolutionary sense since sleepiness could be the body’s way of telling us to relax and conserve energy once we have found and eaten our food, says Denis Burdakov of the University of Manchester, UK, who led the research.\n\n“It has been known for a while that people and animals can become sleepy and less active after a meal, but the brain signals responsible for this were poorly understood,” he says. \n\nBurdakov’s team studied a group of brain cells called orexin neurons, which are found in the hypothalamus and produce proteins called orexins that are essential for maintaining normal wakefulness in humans. These neurons are less active at night and when they malfunction this can lead to narcolepsy, where sufferers cannot stay awake.\n\nFiring rate\nPreviously, researchers have shown that orexin neurons can be inhibited by glucose, but it was not known how sensitive they were. Burdakov’s team exposed orexin neurons to subtle changes in glucose levels similar to those that occur in the blood during daily cycles of eating and hunger, then measured their firing rate. \n\n“What we discovered is the activity of the neurons can be turned off by minute elevations in glucose associated with normal meals,” says Burdakov. The glucose is thought to act on potassium ion channels in the neurons’ membrane. \n\nHe believes this could explain why we naturally feel sleepy after a meal and also why it can be difficult to sleep when we are hungry, since the activity of the neurons would be higher when there is less glucose in the blood.\n\n“We think orexin neurons make sure that we are awake and alert when hungry, in order to ensure optimal food-seeking,” Burdakov says. He adds that it makes evolutionary sense for animals to turn off their wakefulness and conserve energy once they have eaten their food, since it could be risky or wasteful to expend too much energy looking for more food.\n\nObesity trigger\nChanges in the sensitivity of orexin neurons to glucose could lead to obesity, Burdakov speculates. \n\nOrexin neurons are known to help regulate appetite and metabolic rate, and when they become faulty this can trigger late-onset obesity. Researchers are currently trying to understand exactly how orexin neurons interact with other brain circuits involved in appetite regulation.\n\n“The role of orexin neurons in the control of numerous central nervous system processes makes the discovery of their ability to sense small changes in glucose potentially quite important,” says Joel Elmquist at the University of Texas Southwestern Medical Center in Dallas, US, writing in a commentary accompanying the paper in Neuron. \n\nThis is because it means a whole range of physiological processes can be regulated by the amount of fuel that is available. “Dysfunction of glucosensing may have profound effects on wakefulness and coordinated autonomic responses,” he says.\n\nJournal reference: Neuron (vol 50, p 711)
