For the last two weeks, the temperature at home seems to be about 2 degrees Celsius warmer than what the thermometer says, I sweat more at martial arts, my feet seem warmer than usual, even a bit tingly.

I am 44, male, and been eating about 100g carbs/day since August. I consume a lot of olive oil and flax oil, a variety of meat, eggs, milk, and many different vegetables each day. My main activities are martial arts with a small amount of remedial (rotator cuff) weight training.

Anyone have any ideas on what's up here? Could my metabolism be going away up all of a sudden?
