I also get cold feet. I've been inclined to put it down to poorish circulation but apparently that's not an issue for me (well, at the moment, anyway....).
Before I was diagnosed, I had a spell of doing the 5:2 diet and I noticed then that on days when I was "fasting" and by definition didn't have many carbs, I got cold feet; the rest of the time they were fine. Whilst I'm not a doctrinaire low-carber, I undoubtedly eat far fewer carbs than I used to (maybe 75 - 100 g per day) and it's noticeable that, since I started doing this, I've also been more prone to cold feet; not helped by the fact that I work from home most of the time, and sit at a desk most of the day in a rather cool* environment, waiting for the heating to come on
. I wonder, therefore, if there is a link between low carb intake and the temperature of one's extremities?
The other thing I've noticed is that I don't have such a problem in the evening at weekends. The only common factor I can think of is that these are the days when I have a couple (and normally it is only a couple) of drinks before and with dinner. Maybe the alcohol makes a difference? (The drinks are normally scotch and diet ginger, or red wine, so I don't think I am introducing stealth carbs thusly).
I'm no scientist and this is probably all high grade tosh, caused by the random correlation of unconnected events - after all, the incidence of piracy has gone up in line with increases in average atmospheric temperatures,
ergo piracy causes global warming
... But has anybody else noticed similar phenomena?
*(That's cool temperature, not "Hey maaaaannn..."
