Re: Post-Prandial Sleepiness

[Guest guest]

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.

Subject: [ ] Post-Prandial Sleepiness

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.More on my experiments with Lee's revelation in another post.

Rodney -

I'm glad that 'Shurie's Solution' has provided some inspiration for you to experiment with post-prandial sleepiness. I was also interested to read your thoughts about a new eating pattern which incorporates your enjoyment of weekend feasts.

In my case 'Shurie's Solution' was the key to management of Type II Diabetes. I then realized a number of other benefits once I settled upon this new eating pattern. Now I could never go back to the old ways. I notice immediate negative effects if I attempt to eat earlier in the day.

As jwwright mentioned, eating prior to heavy work might be an exception, although I often participate in strenuous sports activities on the weekends without eating prior to 6 PM. I'm often out sea-kayaking on the ocean for 5 or 6 hours. On rare occasions I may eat a small apple or 5-6 cashews during one of these workouts, but most of the time I just skip the food. I drink a lot of water when I'm exercising, but no energy drinks or other carbohydrate laden fluids.

I have no scientific explanation why 'Shurie's Solution' works so well for me, but I arrived at it after quite a lot of experimentation and careful record keeping. I don't make any claims for it, other than it works for me, and I am glad to share it with others as just that: a report of my own personal experimentation and my own personal results.

If it helps others or inspires people like you to experiment and to seek new answers then I am very pleased!

Best regards,

Lee

Hi Lee,

I wondered when you check BG, now that you've got a good plan.

Is it necessary to check it daily?

I only check it occasionally now - perhaps twice a month. I could probably drop it completely since my BG is very well regulated with my diet. For a long time I checked it 5 times per day - as I experimented with diet regimens and refined my current eating plan.

Best,

Lee

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 All,

What is going on with respect to the expected patterns of heart risk

factors to greater versus less frequent feel/day?

Please see the pdf-available below.

Cheers, Al Pater.

Eur J Clin Nutr. 2004 Jul;58(7):1071-7.

Regular meal frequency creates more appropriate insulin sensitivity

and lipid

profiles compared with irregular meal frequency in healthy lean women.

Farshchi HR, MA, Macdonald IA.

....SUBJECTS:: A total of nine lean healthy women aged 18-42 y

....INTERVENTION:: A randomised crossover trial with two phases of 14

days each. In Phase 1, subjects consumed their normal diet on either

6 occasions

per day (regular) or by following a variable meal frequency (3-9

meals/day,

irregular). In Phase 2, subjects followed the alternative meal

pattern to that

followed in Phase 1, after a 2-week (wash-out) period.

....RESULTS:: Fasting glucose and insulin values were

not affected by meal frequency, but peak insulin and AUC

[area under the curve = total insulin/time] of insulin responses to

the test meal were higher after the irregular compared to the regular

eating

patterns (P<0.01). The irregular meal frequency was associated with

higher

fasting total (P<0.01) and LDL (P<0.05) cholesterol. CONCLUSION:: The

irregular

meal frequency appears to produce a degree of insulin resistance and

higher

fasting lipid profiles, which may indicate a deleterious effect on

these

cardiovascular risk factors.

First of all I dont lend much credence to a study done on 9 lean

'younger' healthy women. It's not a large enough sample IMO.

What we're talkin about here is not random eating but eating

commencing at a certain time each day. To my way of thinking -

but I'm not a lean young healthy woman - letting the digestive

sysem rest for part of the day sounds beneficial. Of course I may

change my mind. Another thought on this is one of 'stressing' the

system as advantageous, but I'm not very sure on this one.

Hi Peg:

One thing for certain is that our ancestors ate (pigged out!) when

food was available because they knew next week there would likely be

none at all. Just like the bears in the fall. So I would think

our 'systems' must be capable of handling an extremely erratic meal

frequency, or else our ancestors would never have gotten as far as

having kids.

In any event, the study posted by Al appears to be concerned

with 'irregular' meal frequency. Based on that study just one meal a

day on a regular basis would be excellent : ^ )))

But it would suggest that when I pig out, I ought to do so at the

same time I take my regular meals.

Hi Peg:

Also worth noting that in the Mattson study linked by

earlier today (or was it yesterday?) mice that were fully fed, but

only on alternate days, had insulin and blood glucose data that were

superior even to those on 40% CR.

It doesn't seem likely that one meal per day will harm humans. But

of course we will not know for sure until we see an empirical study,

or two, in humans demonstrating it.

" Nevertheless, intermittent fasting resulted in beneficial effects

that met or exceeded those of caloric restriction including reduced

serum glucose and insulin levels and increased resistance of neurons

in the brain to excitotoxic stress. Intermittent fasting therefore

has beneficial effects on glucose regulation and neuronal resistance

to injury in these mice that are independent of caloric intake. "
