This assumes you have no circulation issues, etc, etc.
You are in a cut at the moment are you not? How long? Actually, your feeling of being cold once in a while, isn't all that surprising to me.
What I have found, is that I am generally more cold when calories are in a deficit, than I am when calories are in a surplus in a 24 hour period. What I eat nor how much I eat at one time doesn't make much of a difference. But the amount of calories consumed (whether deficit or surplus in a 24 hour period) seem to be the stronger element of influence.
Coming from a surplus to a deficit, it "generally" takes about a week or two, approximately, before I feel a difference. But its generally a feeling that comes and goes.
Personally, I feel that some of the temperature (or feeling of a temperature change if you will, while in a deficit in calories), stem from the body shutting down and/or slowing down some biologically expensive operations to conserve energy (which may be more applicable in a long diet trend of calorie and/or macro nutrient deficits and with a person low or very low in body fat). Leptin and variety of other biological processes seem to have a role in the body's (thermostat if you will) as it deals with energy shortages and trying to become more efficient, and it can effect feeling of body temp, and efficiency in other internal processes. This is a rather over simplified example of what "sort of" happens leading into a starvation response (--->or metabolic adaption biologically), and generally its a series of processes, and it does not normally occur overnight, but over some time.
