Sorry if this is a stupid question. I have searched for this and have only found an opinion or two. I noticed that when I dropped 40 pounds that I got chilly easier but it also got colder. But I was taking a break from gym when the cold weather started. Started back up in gym about 2.5 weeks ago and Ive noticed I am warmer at the same climates. My question is does having more muscle mass keep you warmer? Does moderate exercise keep you warm during the day? Thanks in advance!!
