What is the speculation on how this only happens at the midday meal? Or does it happen at all meals?

Perhaps the afternoon nap/siesta/(shop closing in hot climates) has something to do with accomdating this???

Perhaps a brief mid day nap is beneficial in more than a few ways???? Including a longer healthier life? On 100 year old woman I knew enjoyed her brief afternoon nap.

Hi folks:

For as long as I can remember (at least 25 years) I have noticed that if I eat in the middle of the day, no matter what time (any time 11 am thru 3 pm), an hour later I have trouble staying awake. It is a symptom I have put up with, but that I would have liked to 'fix'.

What I have discovered the past week is that Lee Shurie has given us the solution. Don't eat until 6 pm!!! It is odd really. One might have thought that a lack of calories throughout the day might cause drowsiness from an energy deficiency. But in practical terms the opposite is true in my case - if I don't eat I don't become sleepy! The first few days of not eating I did feel hungry, but much less so as the days went by.

On the weekend I did a Pubmed search for 'post-prandial sleepiness'. Interestingly it is clear from what I found that no one knows what causes it. One recent study observed that the majority of subjects reported tiredness after eating, or were more likely to fall asleep in the hour or two after eating. They also noted that consuming a similar amount of water did NOT have the same effect. One study indicated that the type of food consumed was NOT a factor either. So it is quite apparent that the phenomenon is not understood.

Thanks Lee!

Rodney.

I think what causes it is the blood is diverted to digestion and blood pressure at the arm drops. If you are working guys doing physical work they have to be fed because their BG falls, but after feeding you can't let them set around - gotta get back to work. Carbs work the best for that but a little fat will hold them later.

I think the nutrients are kept in an "active" pool until they sit down. Let them rest too long and they'll fall asleep from the BG rise - insulin rise - BG fall. Your work is not physical. I don't eat a large meal unless I'm going outside to work. Then I'll need a combination of carbs, fat and protein. But indoors, I eat small meals, and I don't need near as many calories.

It's probably related to BG like Lee says, but he had Type 2, holding his fasting BG too high.

Sorry for the blank.

For several years I experienced sleepiness after lunch. When I omitted the milk, it stopped. So I think there's possibly an allergy or other at work also. Didn't have that effect with sweetened tea, eg, just milk.

Regards.
