Questions about raising metabolism

Hi, everyone. New poster here…

I just recently read “Eat for Heat” and “Diet Recovery 2” and am intrigued by Matt Stone’s observations about health, diet, and metabolism. I have begun trying to eat much more food as I have a borderline low temperature and often have cold hands and feet, as well as other telling symptoms.

A little background: I’m not a huge dieter – and I think that currently my metabolism operating much better than it was several years ago – but I have recently been doing the 5:2 diet, a form of intermittent fasting.

I do have a few questions regarding RRARF…

First, do I need to increase my caloric intake to such a high degree if my temperature is borderline? My basal temperature (oral) this morning was 98.0, and yesterday morning it was 97.8. I am between ovulation and menstruation right now, so might that be about .5 degrees higher than normal? It seems strange to me that I exhibit so many symptoms (cold hands and feet, low energy, urinating at night, etc.) of a damaged metabolism when it doesn’t seem the thermometer reflects that.

Second, I’ve been trying to pay attention and eat sugar/starch/salt when I notice my hands and feet are cold. But I’ve also noticed that sometimes, after I eat, my hands seem to get even colder. Is this just a reaction of my body struggling to make a shift? My temperature actually did get up to 98.8 today 1/2 hour after 1 of my meals.

Third, I am REALLY thirsty. Is this normal? I am urinating as often as I should be, proper color, I think… Is this just another adjustment my body is going through? Trying not to drink too much…

And finally, besides a struggle to keep excess weight off (although never obese, just a little “chunky”) my main health complaint is sinus problems. I’ve had extensive allergy testing (all negative) and even sinus surgery (unsuccessful). It seems that my metabolism damage perhaps is not too severe…can I expect/hope that adopting this metabolism-enhancing lifestyle might help with my chronic congestion?

Thanks in advance for any advice/help you can offer,
Nancy
