Yep.
D3/K2 helps some.
Mostly it's best to move around for me. I do my workout and I'm good for a bit.
It's just a hazard of eating less. The body adapts by conserving energy. Heat regulation is one of those that gets it. Also, hormone changes play a role in this.

I've talked to a lot of folks. Even those on higher carb diets. They all experience this. I have since I lost the weight. I just wear layers and flail around when I'm freezing. In the coldest days of winter, sometimes I grab my youngest's lap blanket and wrap up in it. Holding a hot cup of something helps.

In my fat ol' days, I was roasting to death all the time. So...funny turn of events.
