Weight Loss Support - What does it mean if I get sleepy after a meal?

I always get sleepy after lunch. I used to think it was a carb crash but now it happens even though I'm not eating carbs. Today I had some cauliflower cooked in olive oil, grilled chicken on top of salad greens, and 3 ounces of cheese. Is it just because I ate a big lunch, even though I barely had any carbs?

I'm interested to see the answers to this. I get the same thing... It's part of the reason I IF. If I eat in the middle of the day I need a nap!

It happens to me as well. And it doesnt matter if I low carb or not. I've tried every macronutrient combo and zzzzzzz.

Val - IF helps and it hurts me. Because the meals tend to be larger with IF, I practically cant fight off the need to nap.

Bodies have to do a lot of work to digest meals. Early afternoon (post-lunch) siestas have some scientific basis / validity!

Coming from a low blood pressure issue, I've been told that one reason people with low BP can have trouble after large meals is because so much blood gets diverted to the stomach and intestines -- blood pressure drops during digestion, and the heart rate increases. (Harvard press release on it here: http://www.health.harvard.edu/press_releases/eating-can-cause-low-blood-pressure)

I assume that happens to everyone - not the intensity of physical symptoms, but the actual physiological processes. For one reason or another, people may just be more sensitive to the effects of a digesting body.

Oh ok good. I just wanted to make sure this was not a sign of something bad like pre-diabetes or something. My blood pressure is relatively low so what you said makes sense.

Desiderata - maybe that is it for me, I have crazy low BP.

I have low BP too!! At last visit it was 80/55. This makes a lot of sense.

Depending on the food, tryptophan/carbs can be the culprit. Carbohydrates help transport tryptophan into the brain, where it can make you sleepy. :)

Low (dizzy-making) numbers unite! :)

Everyone's mileage varies, but I'm curious if anyone else is also very permissive in their sodium intake and will deliberately try to retain water, at times, in order to feel better? I was actually 'prescribed' salt tablets as a pre-teen and acquired them again this past year when my BP regulation bottomed out again. It's nasty for the scale, but extra salt has always helped me when my numbers have crashed out so badly I'm having trouble functioning.

There's a reason for the word 'siesta'. Maybe our bodies are supposed to have an after lunch nap, and the hard working people we've become ignore it.

I don't have low blood pressure but it happens to me as well. I think your body just needs extra energy after meals to digest.

This happens to me as well. It doesn't really matter what I eat, I get sleepy and tired after lunch. That afternoon nap feels so sweet though :D

Same sleepiness here even after a healthy meal. Also in the low BP club.

Another symptom I've noticed for quite a while now is getting cold after I eat a meal, especially supper.

This doesn't happen so much anymore but I used to get a massive head rush every time I stood up. I think it was due to low blood pressure. It's kind of a pain...actually pretty uncomfortable to go blind for several seconds every time you stand up!

This happens to me too. Regularly. My blood pressure never seems particularly low when it's checked though... just on the lower side of normal.

I also get REALLY cold after eating.

As I know, when you eat, your brain diverts energy towards digestion, sending a bunch of red blood cells over to help break down the food and carry the nutrients all over your body. Because so many blood cells are helping out the intestines, the rest of your body takes this time to slow down and relax. As a result, you might feel tired, since your brain doesn't have as many blood cells to help it out at the moment, more energy used for digesting food means less energy can be used for running around!

I go to a "black sheep" doctor who treats hypothyroid and adrenal issues more by symptoms than by raw labwork numbers. One of the symptoms on the list (doesn't affect me, but I have a friend who was in your same boat) is extreme lethargy after meals, and/or "goosebumps"/inablility to stay warm for at least an hour after meals. Just tossin' it out there for consideration. :)

I dont deliberatly increase salt but I dont restrict salt and during the summer I add salt foods to compensate for sweat.

I have low BP but oddly have had very few negative symptoms from it. Rarely feel dizzy or faint.
