One degree

Hi Everyone,
I have been ?watching what I eat? (ie: restricting carbs and calories) for 20 years or so out of fear of gaining back the weight I lost in my early 20s but I am reading Matt’s books and I am going to give it a try because I am sick of being tired and in pain all the time. I have taken my temperature in the morning for the last few days and it has always been around 97.6 so I am wondering how much of a difference that 1 degree actually makes as my hands and feet do not feel particularly cold or anything.
