I used to detest being even slightly warm, refused to have heating on even in winter! Lived in short sleeves and never ever wore a coat! Since losing weight I wear about three hundred and seventy two layers of clothing, I am permanently sat near a radiator or heater (even better if both!) and I own a coat for the first time in my adult life!!! Ketosis causes body temperature to drop plus there's also the obvious factor of less blubber as we lose weight LOL!! I love feeling cold, it shows I'm losing weight!!
