I experienced coldness as a vegan. Cold hands and feet, but especially cold hands. They would never warm up after being wet. This is actually a symptom of long-time smokers, but I never smoked. It's amazing that simply by being vegan I could have that kind of symptom too.

All I had to do was add animal products and BAM! I was warm. SO warm. The first thing I had was a cheese pizza (no meat) and I was already feeling a bit warmer. But then I added lots of eggs and really started to notice. then later meat. Haven't been cold since!

My body temperature drops when I don't eat enough. It goes back up when I eat more. I often wonder how many people with "low body temperatures" are just not eating enough.

Also, keep in mind that the "normal" body temperature range is larger than most realize: see http://en.wikipedia.org/wiki/Normal_human_body_temperature. I can't really tell you "my temp" because it varies during the day like everyone else's. So the fact that body temperature correlates with anything doesn't strike me as particularly significant; it's at best a very coarse measure of health and worrying about it overly much strikes me as a waste of time.

My two cents anyway.

I've been charting my temps for some time (first thing in the morning, oral). My average is 98.3, and the range is 97.7 - 99.1

I notice that a starchier, low-fat meal (yams or the occasional GF starch in an open meal) raises my temperature quite a bit. If I eat high fat and very low carb, I get cold after I eat.

I think low body temperature is a big indicator of low thyroid, at least from my personal experience. My temp for the past 4 or 5 years has been pretty consistently in the 96's, sometimes low 97's.

For the past week I've been following Danny Roddy's advice (pretty in line with Ray Peat) and I've seen a pretty big improvement considering it's only been a week. My body temp was at 98.2 today and I haven't seen that in a long time. Within the first few days I experienced a warm feeling in my hands and feet which I haven't felt in a couple years. I've been feeling pretty good.

It's too early to tell if it's the right way to go, but it sure does seem like it so far.

My basel body temperature averages about 97 'F. Evidently, this is normal:

For most women, 96 to 98 'F is considered normal prior to ovulation and 97 to 99 'F after ovulation.

Mine's really strange - it's always registered a low temp when measured by the doctor or at home, but I've never had cold hands or feet, and don't feel the cold in the winter half as bad as most people. My wife thinks I'm a reptile. Given that it causes me no problems that I'm aware of, I've always ignored it.

I've taken mine at diff times through my life and it always ran a bit low, like about 96F, especially during sleep. I do not have any problems actually getting cold though. In fact, I tolerate cold better than most.

Interesting thing is though, that I have never taken my temp since on paleo, so I just now got off my duff and dug out the thermometer and inbetween bites of steak, took my temp and was surprised to see it rachet all the way up to 99.6! I don't know if the steak is making me hot (I admit it, I have a love affair with steak!), but I think that is the highest temp I have ever measured when not sick. I will have to try it again later and see if it is still high. Very interesting! Good question, thank you. -Eva

My armpits are warm and my toes are cold.

I am reminded of an old joke: "I don't know what apathy is and I don't care."

Personally, I think the body temperature/metabolism stuff is about as valid as Homeopathy (placebos can be very effective). I haven't seen any science that jives with the theory. I am prepared to eat crow if someone can show me some evidence.

i'm at around 95.5 every day -- super-low. i'm hypothyroid, on medication, yet my temperature hasn't increased. when i was off medication i tended to get cold very easily. on medication i don't.

Always had low body temperature, tend to be reasonably slim, but not skinny, and always cold.

My body temp is always around 98.0 upon waking and hovers there for most of the day.. some days after a meal high in carbs it will shoot up to 98.7-9.

I do think there is a correlation between overall metabolic health and body temp, but I'm not really sure how exactly it all works. When I eat low carb I tend to get cold even though the meal is higher in fat. Its all so confusing.. sigh.
