There is a condition termed Hyperthyroidism that you may want to
read up about... in this condition, the body's metabolism speed is
stirred up so much, that it is constantly burning fuel (food)
unnecessarily because of raised thyroid hormone secretions from the
overactive thyroid glands.
The most common cause is Grave's Disease which is an autoimmune
disorder that stimulate the gland to overproduce such hormones.
Thyroid hormones are involved in the millions of processes in the
cells. You will often find these people feeling hot in an extremely
cold weather, even though its 0 C, they will still say it's very
hot, and they will start sweating...
But for your condition above, I would say no, there wouldn't be a
difference in threshold of temperature differences related to the
diet or fluids you consume... Otherwise, you can start a statistic
to find out
