Paleo Diet and Paleolithic Diet Questions & Answers

Question

1

I've been doing VLC for weight loss for some time now, using ketostix to check that I'm staying in ketosis. I've noticed that every evening, several hours after my last meal (and food intake for the day), I get very warm, even rosy-cheeked and almost like a moderate fever.

Could it be related to the ketosis? Does anybody else have this happen when eating minimal carbs? Is it a function of my body burning pure fat? (Oh, please say yes on that one!)

I don't, in fact, I think I get colder, but I've heard it happens to other people.

Same here. I thought at first it was due to being in a weight-loss phase, but even after I settled in at a steady weight I stayed cold. For two years, even during the summer. I'm just now starting to not have icy fingers, and I don't know what's driving the thaw. – Rose Jul 8 2011 at 3:01

drop in Free T3 levels perhaps? I know there is some controversy in regards to ketosis and the effect it has on thyroid hormone production. Thyroid function is normally the first and most obvious thing I think of with cold extremities. – sallycinnamon Jul 8 2011 at 3:29

Could be related. My thyroid levels have improved since going ZC, though. OTOH, I've been in continuous ketosis for so long, that I'm not sure if it's true anymore that I feel colder than usual. Maybe like Rose said, it's more associated with the weight loss itself. I'm not losing much weight these days; I'm pretty close to goal. – Ambimorph Jul 8 2011 at 8:35

Only post-mealtimes. If I don't have a full belly, I'm markedly cooler than I used to be. But then again, I'm 100lbs lighter than I used to be too... so that has a pretty substantial effect.

I'm on VLC, and particularly after breakfast - which is usually bacon, eggs, veggies and a teaspoon or two of coconut oil I am noticeably warmer. During the summer months this can get a bit uncomfortable, so it's lucky I live in the UK. :)

I get the same, but I'm not doing VLC... I actually thought mine were signs of incipient menopause... :)

	Hm, since I'm in the thick of my childbearing years I will venture a guess what whatever it is, it's not menopause...at least not for a while. :) – familygrokumentarian Mar 11 2011 at 2:52
	Let's hope for some guys' answer to disprove my theory... – Paola Mar 11 2011 at 3:04

Yes! It's been key in keeping my heating bills down this winter. 2 TBSP heavy cream and 1 TBSP coconut oil in coffee (shake the coffee and coconut in a container to "churn it") and I'm better than a space heater. My cheeks and ears even flush :)

you know whats strange? my husband (nerd economist) just put our winter energy usage into his dork-spreadsheet and noticed that we used significantly less gas this year than last year (and yes, of COURSE he controlled for outside temperature). last winter i was constantly turning the heat up, but i cant remember a single time doing that this winter. i sort of thought it was the fat that im eating more meat now means that im likely not anemic for the first time in my life. ive certainly not been miserably cold this winter at all. but i wonder if its more to do with carb intake?? ill have to do some experimenting. do you ever take your basal body temp after eating?

can i ask what your primary source of protein was? is it safe to guess that it was beef? if so, i think i am the exact same way as you.

i mentioned this in my post regarding body type according to eastern medicine. post

if possible, try to monitor how you feel after eating vlc with fish or pork. i would not be surprised if you did not feel hot.

Yes!! I'm only on day 3 of VLC and my face feels so warm most of the time, and I'm definitely not wearing as many layers. Fascinating.

Well, I get this from higher protein consumption (and to a lesser degree fat), whether I eat carbs or not.

Both VLC and moderate-carb, eating a primal style diet, I 'burn' MUCH warmer. Am seldom cold in winter (and if I do feel cold I go eat some fat and protein and get all warmed up) and always overheated in summer, which sucks. For a long time I was freezing all the time but tolerated the very hot weather just fine - not any more. I am sweating more than my fat friends, who always had a hard time with the heat.

Do you get really warm when VLC or ZC and are in ketosis?
