Hi Jaden!

I can't say I'm cold all the time, but I've certainly noticed that I'm more sensitive to the cold now than when I was heavier. My thoughts on this are that my "feathers are thinner" so to speak. What I mean is that I have less insulation now than I did when it was cold before and I'm just feeling the effects of that.
You've lost almost 20% of your body weight and your body may simply not have adjusted to that yet.
